Adequate nutrition can be easier said than done. Here’s how to up your intake.

As you ramp up run training in prep for marathon season, you may assume your appetite will follow a similar upward trajectory. But that’s not always the case. 

On the contrary: Intense or prolonged exercise can actually suppress hunger, quashing your desire to eat, Jordan Hill, RD, a Colorado-based registered dietitian and certified specialist in sports dietetics with Top Nutrition Coaching, tells Runner’s World. 

Combine that with other factors—including lack of awareness about what and how much your body needs to sustain training, not having enough time to meal prep, and fear of weight gain—and it’s no surprise that many endurance runners are under-fueled.

Research confirms the struggle: A 2021 study of 207 cross-country runners, for example, found that 79.5 percent of female athletes and and 54 percent of male athletes were at risk of low energy availability (not intaking enough calories to support their workouts and daily needs). 

That’s a problem, since subpar nutrition can trigger a cascade of issues that negatively affect your workouts—and overall health. 

Here, with the help of two registered dietitians, we explain why eating enough calories is crucial to both your run performance and day-to-day functioning, telltale signs you’re underfueling, and easy ways to rev your appetite to help meet your caloric needs. 

Why Adequate Calorie Intake is So Crucial for Runners

Calories are synonymous with energy, Hill explains, so not getting enough calories means you’re not getting enough energy for your body. That deficit can influence pretty much every bodily function including your immune system and metabolism, heart, hormones, GI system, and even mental health, she explains.

More specifically, not getting enough calories can decrease your performance in workouts, lead to excessive fatigue, increased your risk for injury and illness, cause nutritional deficiencies, decrease muscle mass, trigger hormonal imbalances, and cause negative psychological effects, such as mood swings, difficulty concentrating, and increased stress levels, says Hill. In other words, when you don’t fuel enough your body and mind take a serious hit.

Additionally, if you continually eat less than your body needs, you risk suppressing your appetite overall, Amity Lui, MS, RD, a New York City-based sports dietitian who works with runners, tells Runner’s World. “Not eating enough will actually impact your body’s metabolic rate and cause your body to kick into survival mode,” she adds. This means your body will require less calories over time and will shut down certain functions to save energy while increasing storage of body fat, according to Lui. 

In some cases, underfueling can lead to relative energy deficiency in sport (RED-S) syndrome–essentially, a chronic state of low energy availability, Lui explains. Unfortunately, RED-S can cause long-lasting, negative effects, including decreased bone density, chronic fatigue, poor recovery, and diminished enjoyment of running since “you literally have no energy for it,” says Lui.

On the flip side, amping up calorie intake to meet your needs “will reap almost immediate benefits,” says Lui. These include increased energy, mood, cognition, and run performance, she says. You’ll also benefit from enhanced recovery, a strengthened immune system, improved body composition and cardiovascular health, elevated psychological well being, reduced risk for nutritional deficiencies, and improved hormonal balance, says Hill.

Signs of Underfueling

There are a number of signs you’re not eating enough to support your training, and tuning into them can help you rev up your nutrition habits before longer-term problems arise. “If athletes cue into how they’re feeling and what their body is doing, they can usually pick up on not eating enough before RED-S would become an issue,” says Hill. 

Common signs of underfueling, according to Lui and Hill, include:

Decreased energy levels and feelings of abnormal fatigue—think: needing long naps every day, going to bed earlier than usual, or saying no to plans because of fatigue

Decreased performance in workouts—this could include being unable to complete your workouts, or consistently not reaching your target paces

Psychological and emotional changes—examples: mood swings, slowed cognition, irritability, lack of concentration, and generally feeling unmotivated

Prolonged muscle soreness and slow recovery

Getting sick or injured more often

Unintentional weight loss or difficulty maintaining your current weight

Hormonal disruptions, including loss of menstrual cycle

Changes in sleep patterns

Always feeling cold

Hair loss

12 Ways to Increase Appetite

A big reason runners struggle to get in all the calories they need is they simply don’t feel hungry. 

Now, there are a “bunch of ways that our body tells us we’re hungry,” says Hill. You may not always hear your stomach growl, but could instead experience hunger in the form of a headache or fatigue. “It’s important for each person to figure out what’s their individual cue for hunger to help them be aware of that,” says Hill. 

With that in mind, here are 12 expert-backed ways to kickstart your appetite and thus up your chances of eating enough calories. 

1. Eat breakfast

A lot of Lui’s clients report having just coffee as their breakfast, and that’s a no-no. Skipping meals can lead to prolonged hunger, which can suppress your appetite in the long-term. “It’s almost like ignoring your body’s hunger cues,” Lui explains. “If you keep ignoring something, your body will no longer register it as a sign that you need food.” 

Additionally, forgoing the first meal of the day may make it more difficult to achieve your overall calorie totals for the day. Plus, dodging a.m. fuel is associated with nutrient deficiencies and poor diet quality, according to other research. 

Not sure what to chow on? Check out these on-the-go breakfast ideas for runners, plan your breakfast in advance with some meal prepping, or whip up one of these recipes to fuel your morning runs. 

2. Consume smaller, more frequent meals

Instead of cramming all your calories into three big meals—which can be daunting if you’re just not feeling hungry—opt for smaller, more frequent feeding sessions. There’s no perfect cadence, but as a general rule of thumb, aim to nosh every two to three hours, suggests Hill. “It doesn’t have to be full-on meals,” she warns. Nutrient-dense snacks can fit the bill, too (more on that below). 

3. Reach for easy-to-digest fuel post workout

The most common time Hill sees athletes struggle with low appetite is right after a training session, since, like we mentioned, prolonged or intense training can suppress hunger. But getting fuel in anyways—ideally within 30 minutes of a workout—is an important part of the recovery process and can, in many cases, help kickstart your appetite, says Hill. 

Postrun, she recommends reaching for refreshing, easily digestible snacks, like a fruit smoothie, because they’ll be easier to stomach—literally. Lui, for her part, is a big fan of recovery shakes that have a three-to-one ratio of carbs to protein for optimal refueling. 

4. Opt for energy-dense bites

If you’re really struggling to feel hungry, but know it’s time to intake calories, pick higher-calorie, higher-nutrient snacks to maximize the fuel you’re consuming, says Hill. So instead of having just a plate of crackers, have crackers with cheese and deli meat or nut butter, she says. Or in lieu of popcorn alone, combine popcorn with jerky or popcorn and nuts. Other options include Greek yogurt with granola, fruit, chia, or flax seeds; toast with nut butter; or hummus and veggies. The goal, says Hill, is to pair more than one macronutrient together. 

5. Stay hydrated

Dehydration can screw with your appetite, says Hill, so it’s important to stay on top of your intake. Hydration needs vary and depend on factors including how much you exercise and sweat, your overall health, and the heat, humidity, and elevation of your environment, per the Mayo Clinic. As a general rule of thumb, you’re probably adequately hydrated if you don’t feel thirsty and your pee is light yellow or colorless.

6. Consider liquid calories

When hunger just isn’t there, it’s often easier to drink versus chew your calories. That’s where things like smoothies, shakes, juices, and soups can be helpful. “It is less taxing to sip on something versus having to prepare, reheat the food, cook it, and then chew it,” says Lui. To make your sippable meals as nutritious as possible, consider adding nutrient-dense extras like nut butters and seeds, she says. 

7. Find foods you actually enjoy

This may sound like a no-brainer but finding foods you actually enjoy eating—and not focusing so much on what you feel like you should be eating—can help combat a suppressed appetite, says Lui. After all, you’re much more likely to want to nibble when it’s something you genuinely like versus something you feel obligated to choke down. 

8. Reduce fiber intake

High-fiber foods can help keep you ~regular~ but they also keep you feeling full for longer, which may not be desired when you’re struggling with appetite. Fiber-rich meals, like large salads, “can result in bloating and delay gastric emptying, both of which can make you feel less hungry,” explains Lui. So, instead of opting for a kale salad at lunch, consider a grain bowl with quinoa, farro, rice, or barely; in lieu of a whole baked potato at dinner, have a bowl of pasta. 

9. Keep mealtime exciting

Hill explains it this way: “If you’re eating the same thing over and over, you’re already going to be disinterested, and then you throw no appetite on top of that, and it’s really going to make you not want to eat.” 

Beat the mealtime blahs by trying new-to-you flavors and textures. Make a reservation at that just-opened restaurant in town. Or, explore food blogs, watch cooking shows, and follow social media accounts that offer diverse and innovative recipes, suggests Hill. 

10. Pack snacks

To help with eating consistently, carry non-perishable snacks with you—like granola bars or trail mix—so that you’ll have something to nosh on during those times when you’re commuting and transportation gets held up or you end up having to run an extra errand. “I like to call them emergency snacks, even though sometimes I eat them not in an emergency,” says Lui. 

11. Cook with oils

Don’t be afraid to cook with oils, says Lui. This will allow you to get more calories in without having to eat a higher volume of grub. Plus, the fats in the oil enhance the absorption of fat-soluble vitamins, including vitamins A, D, E, and K, Lui adds. So instead of boiling or steaming your veggies, for example, coat them in oil and grill, stir fry, air fry, or sauté them. 

12. Tap an expert for help

Because dietary needs and the factors affecting your appetite can be so individualized, it never hurts to consult a registered sports dietitian for personalized advice. They can help you figure out where you can incorporate more nutrient- and energy-dense meals and snacks into your day, says Lui, as well as determine how you can best fuel for your training goals. 

Ethiopia delivered a remarkable double victory at the 2026 Bank of China Hong Kong-Zhuhai-Macao Bridge Half Marathon on Sunday, November 15, with Wede Kefale and Addisu Gobena emerging victorious in the women's and men's races respectively.

Staged along the spectacular Hong Kong-Zhuhai-Macao Bridge, the event brought together some of the finest distance runners from Ethiopia, Kenya, South Africa and other nations for a fiercely contested 21.097-kilometre challenge across one of the world's most recognisable sea-crossing structures.

The competition produced impressive performances, with Ethiopia showcasing its depth in distance running while Kenyan athletes also secured several places among the leading finishers.

In the women's contest, Kefale produced a composed and determined performance to secure the biggest prize of the day. She crossed the finish line in 1:09:01, holding off a strong challenge from South Africa's Glenrose Xaba, who finished second in 1:09:09. Ethiopia's Fantu Worku completed the podium in 1:09:14, making it an exceptionally close battle among the leading three women, who were separated by just 13 seconds.

The Ethiopian victory was particularly impressive given the quality of the field. Xaba, one of South Africa's leading distance runners, pushed hard throughout the contest but ultimately had to settle for second, while Worku demonstrated Ethiopia's remarkable strength by securing another podium position.

Kefale's victory was supported by an impressive Ethiopian presence throughout the top 10. Baraky Redae finished fourth in 1:09:51, followed by compatriot Asmarech Anley in fifth with 1:10:21. Kenya's Miriam Chebet was sixth in 1:11:05, ahead of Morocco's Fatima Ezzahra Birdaha, who clocked 1:11:23. Kazakhstan's Daisy Jepkemei placed eighth in 1:11:42, while Ethiopia's Zewudie Wudu finished ninth in 1:12:08. Kenya's Priscah Jepleting Cherono completed the top 10 in 1:12:29.

The men's race provided another memorable moment for Ethiopia as 22-year-old Addisu Gobena claimed the overall victory, He clocked 1:01:33 to finish ahead of compatriot Aliyi Kasim, who secured second place in 1:02:29.

Kenya's Alex Lenalepisho delivered a strong performance to take third in 1:02:47, preventing a complete Ethiopian sweep of the men's podium. Morocco's Othmane El Goumri finished fourth in 1:03:07, while Kenya's Abel Kiplimo followed in fifth with 1:03:33

Kenyan representation remained particularly strong throughout the men's top 10. Ezra Kipketer Tanui finished sixth in 1:05:32, followed by Ethiopia's Tafere Adisu in seventh with 1:05:35. Kenya's Meshack Kipchirchir placed eighth in 1:06:01, Benard Kipkorir was ninth in 1:06:15, and compatriot Sena Ledama completed the top 10 in 1:06:21.

Gobena's triumph adds another impressive achievement to Ethiopia's growing presence on the international road-running circuit, while the performances of Kasim and Lenalepisho underlined the competitive depth of the men's field.

The 2026 edition was also significant for the event itself, having earned World Athletics Platinum Label status, placing it among the highest-rated road-running competitions internationally. The bridge provided a spectacular setting for the contest, bringing together elite athletes from different countries for a memorable day of long-distance racing. 

Beyond the podium, the results highlighted the international character of the competition, with athletes from Ethiopia, Kenya, South Africa, Morocco and Kazakhstan featuring prominently in the leading positions.

Ethiopia therefore left Hong Kong with both overall titles, while Kenya had plenty of reasons to take encouragement from its strong representation across both races.

For the organisers, the successful staging of this Platinum Label competition represents another important milestone in the development of road running in Hong Kong. For the athletes, it was an opportunity to test themselves against international opposition on a distinctive course that offered a memorable backdrop to the racing.

American sprint sensation Noah Lyles could be preparing to chase one of the most extraordinary achievements in athletics history after dropping a tantalising hint about his ambitions for the 2027 World Athletics Championships in Beijing, China.

The four-time world 200m champion has sparked excitement among athletics fans after sharing a cryptic message on social media reading “4x ? 2027”, raising speculation that he could be targeting an unprecedented four gold medals when the global championships return to the iconic Bird’s Nest Stadium.

Although Lyles has yet to confirm exactly which events he intends to contest, the possibility of a four-event campaign has become particularly intriguing following World Athletics’ announcement that the mixed 4x100m relay will make its World Championships debut in Beijing.

Such an opportunity could open the door for the American superstar to compete for gold in the men's 100m, 200m, men's 4x100m relay and the newly introduced mixed 4x100m relay.

For Lyles, Beijing could represent much more than another opportunity to add to his impressive collection of championship medals. It could be the stage where he attempts to establish himself as the most successful male athlete in World Athletics Championships history.

The 100m would undoubtedly be one of his biggest attractions. Having claimed the world title in Budapest in 2023 before completing his remarkable rise to Olympic glory at the Paris 2024 Games, Lyles knows exactly what it takes to rule the world's premier sprinting stage. However, he will be eager to reclaim the global crown after settling for bronze behind compatriots in the 2025 World Championships in Tokyo.

The 200m, meanwhile, remains his strongest territory. Lyles has established an extraordinary legacy over the half-lap distance, winning four consecutive World Championships titles in 2019, 2022, 2023 and 2025. In Tokyo, he matched Usain Bolt's remarkable achievement of four successive world 200m crowns, further strengthening his reputation as one of the greatest performers the event has ever witnessed.

His ambitions would also extend to the relays, where he has repeatedly demonstrated his value to Team USA. Lyles has already collected four World Championships gold medals in the men's 4x100m relay, including victories in 2019, 2022, 2023 and 2025. Another successful campaign in Beijing would provide an opportunity to add to that impressive record.

The introduction of the mixed 4x100m relay could make the challenge even more fascinating. With the event officially scheduled to make its World Championships debut in Beijing, the competition will offer another opportunity for the world's leading sprinters to showcase their speed on the global stage.

Beyond the possibility of four gold medals, however, there is an even bigger historical prize waiting for Lyles.

The American currently boasts eight World Athletics Championships gold medals. Winning four more in Beijing would take his career tally to 12, moving him beyond Jamaican sprint legend Usain Bolt, whose 11 world titles remain the benchmark for male athletes in the competition's history.

That would be a remarkable achievement for an athlete who has never hidden his admiration for Bolt and his desire to reach the heights established by the Jamaican legend.

Interestingly, the Bird's Nest Stadium carries its own special place in sprinting history. It was at the same venue during the 2008 Beijing Olympic Games that Bolt announced himself to the world with his breathtaking performances in the 100m, 200m and 4x100m relay. Nearly two decades later, the iconic stadium could provide the setting for another extraordinary chapter in sprinting history.

For Lyles, the challenge will be enormous. Successfully navigating four demanding events, managing the competition schedule and delivering at the highest level across individual and relay races would require exceptional preparation, consistency and teamwork.

Nothing has yet been confirmed regarding his participation in all four disciplines, but his intriguing message has certainly given athletics followers something exciting to anticipate.

Could Beijing 2027 become the championship where Noah Lyles transforms an ambitious dream into an unforgettable reality?

Four events, four potential gold medals and the possibility of surpassing one of the greatest sprinting legends of all time. The countdown to Beijing promises to be fascinating.

What began as one of the most entertaining and talked-about stories of the 2026 New York City Marathon has taken an unexpected turn, with Houston-based lawyer Andrea Sager losing her official race result after a viral video showed her smoking marijuana during the event.

The 35-year-old mother of two attracted widespread attention on November 1 when she lined up for the iconic 26.2-mile race wearing a bright pink running vest carrying a humorous personal advertisement: “Andrea, 35, Single. Great Credit. Bad Judgment.” The unusual message quickly made her one of the most recognizable personalities among the thousands of participants, generating plenty of reactions from spectators and social media users.

However, it was another moment captured on camera that eventually landed her in trouble with race organizers. A video circulating online showed Sager accepting a puff of marijuana from a spectator while running along the marathon course, turning what had initially been a lighthearted appearance into a much bigger controversy.

Following the circulation of the footage, New York Road Runners (NYRR), the organization responsible for staging the marathon, removed Sager's finishing time of 5:54 from the official results after determining that she had violated its Code of Conduct. The regulations prohibit smoking, vaping and the use of tobacco or marijuana products in the starting corrals, along the course and within the designated race areas.

Despite the disqualification, Sager was allowed to retain her physical finisher's medal, meaning she still has a memento of completing the demanding journey through New York's five boroughs, even though her official finishing result no longer stands.

Sager has since offered an explanation for her decision, revealing that she was struggling physically as the race progressed. With considerable discomfort in her legs and the marathon becoming increasingly difficult, she said she accepted the offer from a spectator in an attempt to manage the pain and make the remaining miles more bearable.

Interestingly, the controversy has not entirely dampened her enthusiasm for the experience. Rather than retreating from the attention, Sager has embraced the unexpected publicity, revealing that the viral moment has brought considerable interest on social media and dating platforms.

Her distinctive pink running vest has also become a talking point beyond the marathon, with the attention opening up potential opportunities for merchandise and brand partnerships inspired by the memorable message.

Although she initially challenged the decision, Sager has acknowledged that the organizers were enforcing their regulations and appears to be taking the outcome with a sense of humour. She has also indicated that she could return to the marathon distance in the future, suggesting that her New York experience may not be her last.

For Sager, the 2026 New York City Marathon will undoubtedly be remembered for reasons far beyond the challenge of covering 26.2 miles. She arrived at the starting line hoping to enjoy her first marathon and perhaps attract a little attention with her unusual outfit. Instead, she left with a viral story, unexpected publicity and a disqualification that has made her one of the most talked-about recreational runners from this year's event.

Her finishing time may have disappeared from the official results, but her story has certainly found a place in the conversation surrounding this year's marathon.

After all, completing a marathon is an achievement in itself, but Andrea Sager's New York experience came with a twist that few runners could have anticipated!

World mile record holder Josh Kerr has sparked an interesting conversation among runners after questioning the growing popularity of hydration vests, suggesting that many athletes may be carrying more equipment than they actually need for their everyday training sessions.

The British distance-running star shared his thoughts during a Reddit Ask Me Anything session hosted by BBC Sport on Monday, where he responded to questions from fans about training, competition, rivalries and some of the lighter aspects of his life as an elite athlete.

Among the most relatable topics was the increasing use of hydration vests, a piece of equipment that has become increasingly common among recreational runners, particularly those who head out for regular training sessions.

Kerr offered a straightforward perspective, suggesting that runners covering distances of less than 12 miles (approximately 19 kilometres) generally do not need to carry water with them. He believes that some running trends are driven more by marketing than genuine necessity, using hydration vests as an example of equipment that has perhaps become more popular than it needs to be.

He further pointed out that runners training in urban environments can usually find somewhere to purchase a drink if they need one, rather than carrying additional equipment throughout their entire run.

However, his comments were not intended as a universal rule for every athlete. Hydration requirements differ depending on individual needs, weather conditions, training intensity and the distance being covered. Runners tackling longer distances, particularly in hot conditions or on remote trails, may still benefit considerably from carrying their own fluids.

Away from the equipment debate, Kerr also addressed questions about his relationship with Norwegian distance-running superstar Jakob Ingebrigtsen. Keeping his response brief and humorous, the Briton remarked, "I wouldn't say we're buddies!" However, he acknowledged that rivalries are an important part of athletics and can help make the sport more exciting for competitors and spectators alike.

The 2024 Paris Olympic Games also featured prominently in the discussion, particularly the men's 1500m final, where Kerr secured the silver medal in a British record of 3:27.79 behind American Cole Hocker.

Despite narrowly missing out on Olympic gold, Kerr insisted that he had no regrets about how he approached the race, reflecting the confidence and competitive mentality that have helped establish him among the leading middle-distance runners in the world.

The Scottish star also offered fans a glimpse into the demanding training sessions behind his remarkable mile world record, providing insight into the preparation required to compete at the highest level. He additionally touched on the possibility of eventually moving up to the marathon, a prospect that will undoubtedly attract considerable interest given his credentials over shorter distances.

Not every question, however, was about world records, Olympic medals or gruelling workouts. In one particularly amusing moment, Kerr was asked how far he thought he could run on just a single square sausage and a can of Irn-Bru, bringing a distinctly Scottish flavour to the conversation.

The exchange offered a refreshing look at the personality behind one of Britain's biggest athletics stars, showing that even athletes operating at the very highest level have plenty of opinions about everyday running habits.

For recreational runners, Kerr's message about hydration vests is certainly worth considering, although individual circumstances should always determine what equipment is necessary. His broader point was simple: runners should understand their actual training needs rather than automatically following every new trend in the running industry.

Kenyan marathon star John Korir is preparing to chase a remarkable piece of history at the 2026 Valencia Marathon, where victory could make him the first male athlete in more than two decades to successfully defend the prestigious title.

The 30-year-old, who will celebrate his birthday just four days before the December 6 race, returns to Spain with an opportunity to achieve something that has proved exceptionally difficult in the history of the competition. Having conquered the Valencia streets last year in an outstanding 2:02:24, Korir now has his sights firmly set on becoming a two-time consecutive champion.

A successful defence would place Korir in an exclusive group of athletes who have managed to win Valencia's men's marathon twice. The race's historical records identify only three previous multiple winners: Teodoro Pérez, Eduardo Alcaína and Samuel Tangus. Tangus remains the last man to achieve consecutive victories, having triumphed in 2002 and 2003.

Korir's opportunity has become even more promising following the withdrawal of Ethiopian star Yomif Kejelcha, who was ruled out of the December 6 contest because of an injury. Kejelcha had been among the biggest attractions in the anticipated showdown. His absence removes a major challenger and leaves Korir as one of the leading favourites heading into the race.

The Kenyan's recent performances explain why expectations are so high. He has established himself among the world's most formidable marathon runners, collecting major victories in Chicago in 2024, Boston in 2025, Valencia in December 2025 and Boston again in April 2026. His latest Boston triumph was particularly impressive, as he successfully defended his crown in a spectacular course-record time of 2:01:52.

However, Korir is not returning simply to defend his title. He has much bigger ambitions, with reports indicating that he is targeting a historic sub-two-hour performance on Valencia's famously fast course. To prepare for that challenge, the Kenyan has reportedly increased his training volume to between 250 and 270 kilometres per week, demonstrating the scale of preparation behind his ambitions.

Breaking the two-hour barrier would be an extraordinary achievement, particularly on a course where the current men's record stands at 2:01:48, set by Ethiopia's Sisay Lemma in 2023. Korir already knows what it takes to deliver a major performance in Valencia, having produced a commanding victory last year.

Turning 30 just days before the competition, Korir appears to be entering an exciting period of his marathon career. His combination of experience, consistency, confidence and remarkable endurance makes him a serious contender not only for another victory but also for a possible assault on the course record.

For Korir, December 6 represents an opportunity to go beyond another major marathon victory. He could end a 23-year wait for a consecutive men's champion in Valencia, join an exclusive group of multiple winners and potentially deliver one of the fastest marathon performances ever witnessed.

The challenge is now clear: defend his crown, make history and perhaps bring the world closer to another landmark moment in marathon running.
