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.

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. 

Melissa Jefferson-Wooden delivered a sensational performance in Budapest, storming to victory in the women’s 100m at the inaugural World Athletics Ultimate Championship in a breathtaking 10.62 seconds.

The American produced a superb display of acceleration and composure to claim the World Ultimate Championship title while recording the fastest women’s 100m time in the world this year. Her 10.62 mark underlined her exceptional form and placed her firmly at the top of the global sprinting hierarchy.

Jefferson-Wooden controlled the race through the decisive stages and maintained her form all the way to the finish to secure a statement victory against a field packed with championship pedigree. She crossed the line ahead of Olympic champion Julien Alfred, who clocked 10.74 seconds with a -0.2 m/s wind, while Sha’Carri Richardson took third in 10.76.

Women’s 100m Final

1. Melissa Jefferson-Wooden — 10.62

2. Julien Alfred — 10.74 (-0.2 m/s)

3. Sha’Carri Richardson — 10.76

The victory was especially significant given the quality of the opposition. Jefferson-Wooden held her nerve against Alfred and Richardson, two of the most accomplished sprinters of the current generation, to produce the fastest performance in the world this year when it mattered most.

Alfred once again demonstrated her consistency at the highest level by taking silver, while Richardson completed an all-star podium in a race that brought together three of the biggest names in women’s sprinting.

But beyond the time, the title and the celebration, one of the most touching moments came after the race when Jefferson-Wooden embraced her father, Melvin, in an emotional celebration.

Their moment carried a deeply personal meaning. When Melissa was just 17 years old, she donated her stem cells to help her father undergo a bone marrow transplant after he was diagnosed with myelodysplastic syndrome. Years later, the two shared an unforgettable embrace in Budapest after she had become the World Ultimate Champion.

For Jefferson-Wooden, however, the evening was about far more than a medal. It was the culmination of an extraordinary journey, now highlighted by a world-leading 10.62 seconds on one of the biggest stages in athletics.

With the Ultimate Championship title secured and her father by her side, Jefferson-Wooden leaves Budapest with more than being an ultimate champion. She leaves with momentum, confidence and a powerful statement of intent — turning a high-profile showdown into one of the defining sprint performances of her season.

Audrey Werro has added another major title to her extraordinary season, storming to victory in the women’s 800m at the inaugural World Athletics Ultimate Championships in Budapest.

The Swiss star delivered a commanding performance, taking control from the opening gun and refusing to surrender the lead as she powered through an absorbing battle against two of the biggest names in the event.

Werro stopped the clock at 1:55.88 to become the Ultimate Championships 800m champion, producing another statement performance on one of the sport’s newest and most prestigious stages.

Behind her, Great Britain’s Keely Hodgkinson fought her way to second in 1:56.26, while the Netherlands’ Femke Broeders-Bol completed the podium in 1:56.74.

The result once again brought together the same formidable trio that featured on the podium at the European Championships, but Werro again proved to be the athlete who could rise above the challenge when it mattered most.

Her Budapest triumph is the latest chapter in a season that has already included records, a successful Diamond League Trophy defence and European Championship gold. Now, she can add the Ultimate Championships crown to a growing list of accomplishments.

Werro’s consistency has been particularly impressive in an 800m event packed with elite talent. Rather than simply relying on a fast finish, the Swiss athlete showed her authority by taking the initiative from the beginning and maintaining enough strength and composure to hold off Hodgkinson and Broeders-Bol all the way to the line.

The victory also underlined the remarkable depth of the women’s 800m, with three athletes separated by less than a second at the finish. Hodgkinson’s 1:56.26 and Broeders-Bol’s 1:56.74 showed just how fiercely contested the race was, but Werro’s decision to dictate the pace ultimately gave her the decisive advantage.

For Werro, this was more than another medal. It was another opportunity to demonstrate that her rise is no passing moment. On a stage featuring established champions and elite rivals, she once again produced the performance required to claim the biggest prize.

For Hodgkinson, the silver medal adds another major podium finish, while Broeders-Bol once again demonstrated her ability to compete with the very best over two laps.

But the spotlight in Budapest belonged unmistakably to Werro.

With another championship crown secured, the Swiss star has strengthened her claim as the athlete setting the standard in women’s 800m running. This is Audrey Werro’s era — and the rest of the field is chasing.

Busang Collen Kebinatshipi has delivered another sensational performance, storming to victory in the men’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The reigning world champion stopped the clock at an astonishing 43.39 seconds, smashing his own Botswana national record and moving to fifth on the world all-time list.

Kebinatshipi produced a commanding finish to pull away from his rivals and secure the Ultimate Championship title. American star Rai Benjamin finished second in 44.15, while Jereem Richards of Trinidad and Tobago completed the podium in 44.23.

 Men’s 400m

1. Busang Collen Kebinatshipi — 43.39 NR

2. Rai Benjamin — 44.15

3. Jereem Richards — 44.23

The performance is even more remarkable considering that Kebinatshipi had already rewritten the Botswana record just one week ago in Brussels, where he ran 43.40. In Budapest, he lowered that mark by another 0.01 seconds to establish a new national record of 43.39.

That improvement has also propelled the 22-year-old into rare territory. His latest time now ranks him fifth fastest in history over 400m, placing him among an extraordinary group of athletes who have broken the 43.40 barrier.

Kebinatshipi's victory also caps an extraordinary season for the Botswana star. After establishing himself as a global champion, he has continued to demonstrate that he belongs among the very best one-lap runners in the world.

And there is a major reward for his historic night in Budapest: Kebinatshipi walks away as the Ultimate Champion and $150,000 richer.

From another national record to a place among the five fastest 400m runners ever, Kebinatshipi has turned an already remarkable season into something truly special.

Botswana has its latest sprinting superstar — and Kebinatshipi is showing that his ceiling may be even higher than anyone imagined. 

Marileidy Paulino once again proved why she is the undisputed queen of the one-lap event, powering to victory in the women’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The Dominican Republic superstar produced a sensational 49.07 seconds to claim gold, pulling decisively away in the final straight and holding off a fiercely competitive field to extend her remarkable unbeaten run.

Paulino delivered her trademark combination of controlled speed and devastating finishing strength. She remained firmly in contention through the opening stages before unleashing her decisive move down the home straight, where she quickly opened a gap on her closest challengers.

Norway’s Henriette Jæger mounted a strong challenge but could not match Paulino’s finishing speed, crossing the line second in an impressive 49.28. Jamaica’s Nickisha Pryce completed the podium after clocking 49.56, ensuring that three of the world’s leading 400m talents occupied the medals.

The result once again underlined Paulino’s extraordinary consistency at the highest level. She entered Budapest as the world leader after running 48.48 in Paris in June, a performance that also set a Diamond League record. She subsequently remained unbeaten throughout her Diamond League campaign, closing the circuit with a meeting-record 48.64 in Brussels.

Budapest has also become a special venue in Paulino’s career. Three years ago, at the same National Athletics Centre, she captured her first individual world title, marking the beginning of another dominant chapter in her career. She later added Olympic gold in Paris in 2024, further establishing herself among the defining 400m athletes of her generation.

The inaugural World Athletics Ultimate Championship has brought together the sport’s biggest stars in a new winner-takes-the-spotlight format, with Olympic and world champions, Diamond League winners and leading performers competing for ultimate honours.

For Paulino, the occasion once again ended with Ultimate Crown on her arms.

With 49.07 seconds, she did more than win another major 400m title. She delivered another statement of authority, powering through the final straight with the confidence and speed that have made her one of the most dominant figures in modern women’s athletics.

Marileidy Paulino remains unbeaten, remains relentless and, once again, remains the queen of the one lap.

Jakob Ingebrigtsen has made a major decision regarding the remainder of his World Athletics Ultimate Championship campaign, confirming that he will withdraw from the men’s 1500m in Budapest despite producing a sensational performance to win the 5,000m title.

The Norwegian superstar stormed to victory in the inaugural Ultimate Championship 5,000m on Friday night, clocking a season-best 12:59.24 and delivering a devastating finishing kick to defeat Olympic 5,000m champion Cole Hocker and American Parker Wolfe.

Ingebrigtsen’s final 100 metres was arguably the defining moment of the race. The Olympic champion produced a remarkable 12.60-second closing 100m, powering away from the field to secure the $150,000 winner’s prize and underline just how far his fitness has progressed since returning from Achilles surgery.

The victory was particularly significant after what has been an extremely difficult period for the 25-year-old. Earlier in the season, Ingebrigtsen faced serious uncertainty over whether he would even be able to compete at the highest level again. His return has gradually gathered momentum, and his performance in Budapest offered perhaps the clearest indication yet that the Norwegian is rediscovering his formidable racing ability.

But rather than risk pushing his recovering body further, Ingebrigtsen has now opted to step away from the 1500m.

The decision means the highly anticipated showdown with British rival Josh Kerr will not take place in Budapest after all. The two stars had been expected to renew one of the biggest rivalries in modern middle-distance running in the 1500m final.

Instead, Ingebrigtsen is looking beyond the immediate opportunity and towards the bigger picture.

“I’m thinking about 2027… Fitness cannot be faked,” the Norwegian said, signalling that protecting his long-term condition has become more important than chasing another major victory only days after his return to peak-level competition.

The decision comes just one week after an emotionally charged Diamond League Final in Brussels, where Ingebrigtsen finished fourth in the 1500m behind Australia’s Cameron Myers, Kenya’s Phanuel Kipkosgei Koech and American Ethan Strand.

After that race, Ingebrigtsen delivered a fiery assessment of his rivals and questioned the tactics surrounding the pacemaking, particularly involving Hocker. He later acknowledged that there had been “a little too much adrenaline and emotion” when microphones were placed in front of him immediately after the race.

Yet his latest decision shows that beneath the emotion and competitive intensity lies a longer-term strategy.

Ingebrigtsen has already demonstrated that he can compete at an elite level again. His 12:59.24 in Budapest was not simply a victory — it was a statement that the Norwegian remains capable of producing a world-class finish even after months of injury rehabilitation.

Now, however, he is choosing not to gamble with that progress.

For a runner who has spent much of the year fighting his way back from injury, another 1500m race could have offered enormous rewards but also carried unnecessary risk. By withdrawing, Ingebrigtsen is effectively prioritising longevity over one more opportunity for immediate glory.

His message is clear: the comeback is underway, but it will not be rushed.

The 5,000m victory has given Ingebrigtsen confidence, momentum and perhaps, most importantly, proof that his body can once again handle elite competition.

Now comes the harder part — knowing when to stop.

With 2027 already firmly in his sights, the Norwegian has chosen recovery over risk. And after everything he has endured, that could ultimately prove to be one of the most important decisions of his comeback.

Jakob Ingebrigtsen is not walking away from the sport. He is protecting his future in it.
