When approached realistically, running can be an excellent tool for weight loss and weight management, but don’t be fooled by the numerous myths surrounding them

People often start running to drop a few pounds. Hopefully, they fall in love with it, move beyond the number on the scale and continue running for its many other benefits; but for many people, it’s impossible to decouple running from the weight-loss goal. When done correctly, running can help people struggling with excess weight to shed pounds—and continuing to run can be effective way to keep them off. But the subject of running and weight loss is fraught with mythology. We delve into some of the problems with the weight-loss approach to running, including what actually works, what definitely doesn’t and how to keep running as part of your life, regardless of whether you lose weight.

Myth

You can run a marathon PB while dropping 10 pounds

You can do anything, but you can’t do everything. As a rule, you won’t boost performance at the same time that you’re purposely losing weight. Often, the opposite is true, says Kylee Van Horn, RD, owner of Flynutrition in Boulder, Colo. When you’re restricting your food intake, you’re unlikely to make performance gains, but unfortunately, we often equate being faster with being thinner.

“The first thing I tell a client with a weight-loss goal is that losing weight will not necessarily make you a faster runner,” adds Carla Rodriguez Dimitrescu, PhD, an Edmonton-based expert in nutrition and metabolism who works primarily as a running coach. It’s fine if weight loss is your goal—but don’t confuse it with performance, because the way that you’ll get faster isn’t necessarily the way that you’ll drop a pound a week (which should be the maximum weight you’re losing per week, unless advised otherwise by your doctor).

Myth

There is one “runner’s body”

Let’s be clear: there is no single body type that signifies “runner.” Often, people with weight-loss goals who run have a vision in their minds of the long, lanky phenotype often associated with marathoners. But runners come in all shapes and sizes—and if you run, you have a runner’s body, period.

Even in the professional sphere, there are different body types that excel at different types of running. “You would never tell a professional runner that he doesn’t look like an astrophysicist,” says Dimitrescu. “But for some reason, that astrophysicist is upset that he doesn’t look like a runner.” She adds that people have different somatotypes, which means that genetics and environment will both play a role in how running (or dieting, or strength training) changes your body. And if you really want to see how every body is a runner’s body, sign up for a local 5K race and look around you at the start.

Still, the “runner’s body” myth runs deep, and it can be hard to break free of the desire to be ultra-thin. That’s why Stevie Lyn Smith, RD, a board-certified sports dietitian based in Buffalo, N.Y., tries to focus her clients on health outcomes as well as esthetic goals. “We try to look at other goals, like running your personal best in a race,” she says. “Maybe you won’t achieve whatever physique is jammed in your mind as the ‘ideal,’ but you’re able to appreciate these non-body-focused victories.”

Myth

Lighter is healthier/faster

Here’s an oversimplified example: say you’ve had the stomach flu for a week. You’ve lost seven pounds during that time, thanks to days spent in agony. You head out for your first run since you got sick. How does it go? That’s right—dropping weight doesn’t always lead to speedy running, and while that’s an extreme example, it’s not much different from how you’d perform after a week of crash dieting.

“Slimmer is not necessarily better,” says Dimitrescu. “And too much weight loss or restriction can lead to issues like stress fractures, increased rates of illness and injury and chronic fatigue. That’s not going to make you healthier or faster.”

And unfortunately, Don Henley was right when he sang, ‘You can’t go back, you can never go back.’ If, at 46, you’re mourning your running prowess or body composition from when you were 17, you may need to come to terms with the fact that your body isn’t the same, and no amount of training or restricting will get you there. You need to find your new healthy, speedy body, says Van Horn.

Myth

Runners can lose weight faster by eliminating carbs

Skip any diet that eliminates entire macronutrient groups, says Dimitrescu. These fad diets come and go, and for someone who wants to be a healthy, optimized runner, they’re just not worth it. “I don’t like any restrictive diet that advocates for super low calories or eliminates a macronutrient,” she says.

“My priority is always that clients get plenty of protein—at least one gram per kilogram of body weight—and adequate carbohydrates. People have a fear of carbohydrates, but if you don’t eat enough carbs, you’re going to use the protein as your source of energy instead of using it to help build and repair muscle. You’re not doing any favours to your body if you don’t provide it with the energy it needs to do the work that you’re asking it to do.”

Myth

Running earns you calories

A common saying about running is that you run to eat. But really, you should be eating to run. “Don’t create a reward/punishment mentality around running and food,” says registered dietitian and runner Lindsey Elizabeth Cortes of San Antonio, Texas. “Try to focus on how you fuel and how you train as lifestyle choices and not things that need to be rewarded or punished.”

For example: it’s not, “I had a great run, so now I get to reward myself with nachos,” nor is it “I had a bad run, so now I can only eat a salad.” Instead, reframe to: “I ran, and now I’m craving nachos! Maybe I’ll have nachos with a salad.” Or, “I didn’t run, and I’m craving nachos. Maybe I’ll have nachos with a salad.”

Myth

Fasted running and intermittent fasting will speed up weight loss

Yes, fasted runs and intermittent fasting may potentially have some longevity and fitness-based benefits, but when it comes to weight loss, they’re not going to move the needle. In fact, they might be sabotaging your efforts. “For most people, things like fasted runs and intermittent fasting just equate to saving up their calories until the end of the day and then overdoing it in the evening, or using these so-called ‘healthy’ concepts to put a healthy spin on unhealthy, restrictive eating patterns,” says Van Horn. “But if you look into the research, there’s no benefit for doing fasted training for weight loss. In fact, we know that fasted running can raise cortisol levels, which can make weight loss harder.”

Intermittent fasting that takes place around your running window means that your runs aren’t being fuelled—which can both decrease your running performance and make it harder to lose weight, since you’re more likely to over-indulge later in the day. “At minimum, fuel around your workouts and during your training, so that you have enough calories on board to develop some adaptations and buffer the stress of the workout,” says Van Horn. She adds that if weight loss is the goal, you can reduce calories at meals that aren’t near your workout window. Calories should come out of meals that aren’t right before or after your runs. Lowering your portion of rice with dinner or cutting out dessert if you trained in the morning will give you greater results than skipping your post-run snack. (But keep your caloric deficit at a maximum of 500 calories per day.)

Things like fasting and fat adaptation (training your body to optimize fat over glycogen for fuel) may sound like they’re about weight loss, but the reality is that neither is likely to help you lose weight. Some research has found that when done under the right conditions, they might increase certain health markers or improve longevity, but they’re not the weight-shedding tools you may think they are.

Myth

The more you run, the more weight you lose

The natural inclination of someone who wants to lose weight by running is to run longer. Usually, the idea of training for a marathon or half-marathon gets floated around. But running shorter routes, with some harder efforts thrown in, will lead to better weight loss outcomes, because you’re able to get the benefits of the run cardio without as much stress on the body. And because the more you run, the more you need to fuel, chasing higher mileage is actually a bit of a fool’s errand, where weight loss is concerned.

“Endurance sport is not a weight management tool,” says Smith. “Volume-wise, if you’re running more than 10 hours a week while also working a normal job, spending time with family, dealing with all of those normal responsibilities, the long-term stress of that is not going to be conducive to weight loss. With a more appropriate training load for your current lifestyle, it’s easier for you to manage stress, and you’ll see better results.”

Myth

The number on the scale is the only number that matters

Rather than focusing on your weight in pounds, look at different metrics. “I like a combination of measurements with a soft tape measure, how a certain item of clothing fits, and scale weight done once a month,” says Van Horn. While body composition-measuring tools like a DEXA scan are often considered the gold standard, they are expensive and often difficult to access, so rather than spending time and money on that, focus instead on simple measurements that are replicable.

Daily weigh-ins are also a mistake, says Van Horn. Our bodies fluctuate from day to day, so scale weight on a daily basis can be disheartening. Instead, shift to weekly or monthly and look for a general trend rather than placing any importance on half a pound.

Finally, it’s not all about your body weight or size. Dimitrescu recommends looking at fitness and health markers, such as your resting heart rate, blood glucose levels, and HDL and LDL cholesterol. Often, these markers will improve quickly once you adopt a running habit and focus on healthy eating, and can help you see that even if the number on the scale isn’t changing, your body is.

In fact, research has shown that a focus on getting into the habit of running regularly actually is more effective for long term weight loss than focusing on the number on the scale—so it may be worth shifting your focus to the number of times per week you’re physically active, or minutes spent moving.

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

The men's 100 metres at the 2026 Rome Diamond League is shaping up to be one of the most anticipated sprint races of the season, with an exceptional field featuring some of the fastest men in the world.

Scheduled for Thursday, June 4, at the iconic Stadio Olimpico in Rome, the race will bring together reigning stars, established champions and emerging talents in a contest that promises fireworks from the moment the gun goes off.

Kenya's Ferdinand Omanyala headlines a world-class lineup that includes American sprint sensation Noah Lyles, Botswana's Olympic champion Letsile Tebogo, Jamaica's explosive Ackeem Blake, South Africa's ever-consistent Akani Simbine and Italy's hometown hero Lamont Marcell Jacobs. With personal bests ranging from 9.77 to 9.97 seconds, the field is packed with athletes capable of producing something special on the Diamond League stage.

Omanyala, the African record holder with a blistering personal best of 9.77 seconds, arrives in Rome eager to continue his strong early-season form and prove he can challenge the very best on the global circuit. The Kenyan star has built a reputation as one of the fastest starters in world sprinting and will be looking to make a statement against an elite field.

Standing in his way is world champion Noah Lyles, whose personal best of 9.79 seconds places him among the fastest athletes in history. The American remains one of the sport's biggest attractions and will be determined to add another Diamond League victory to his impressive résumé.

The race also marks a major test for Olympic champion Letsile Tebogo. The Botswanan star has rapidly become one of athletics' most exciting talents, while Ackeem Blake continues to establish himself as a serious contender on the international sprint scene.

Adding further intrigue is the presence of Italy's Lamont Marcell Jacobs. Competing on home soil, the Tokyo Olympic champion will enjoy passionate local support as he seeks to deliver a memorable performance in front of the Roman crowd.

South Africa's Akani Simbine, Cameroon's Emmanuel Eseme, Great Britain's Jeremiah Azu and rising American talent Jordan Anthony complete a field that boasts remarkable depth and quality.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
