“I can’t lose weight like I used to. I must be eating too many carbs”

“Do you think a keto diet is a good way to drop a few pounds?”

Judging by the phone calls I get from potential clients, an increasing number of runners of all ages are complaining, “Why can’t I do something as simple as shed a few pounds???” They are frustrated and at a loss about what to do to lose undesired body fat.

  Speaking at the annual meeting of the American College of Sports Medicine (June 2021; www.acsm.org), Kevin Hall PhD explained that fat loss is far from simple. Dr. Hall works at the National Institutes of Health. His laboratory investigates how metabolism and the brain respond to a variety of changes in diet and exercise. His research has helped identify the complex mechanisms that regulate weight.

Weight loss is not simple

  You’ve likely heard, “A pound of fat equates to 3,500 stored calories. To lose one pound of body fat a week, you can simply knock off 500 calories a day—or burn off 500 calories more than usual, or some combination of the two.” Hall explained the “simple” approach to weight loss just doesn’t hold true. Runners who are chronic dieters would have shriveled up and disappeared by now. Not the case.

     Weight loss is not simple because our bodies adapt to “famines” by conserving energy. When food is scarce, be it a famine or a diet, the body conserves energy (metabolism slows, spontaneous movement lessens) and simultaneously appetite increases. Hence, eating less (dieting) takes persistent effort. The greater the energy deficit and the greater the weight loss, the greater the increase in appetite. Losing weight becomes more and more challenging. Hence, most runners end up unwilling or unable to sustain for a long time a diet with a calorie reduction of 25%. For a typical female runner who maintains weight at about 2,400 calories, that’s an 1,800-calorie reducing diet. Based on my experience, runners inevitably self-imposed a 1,200 – 1,500 calorie reducing plan. No wonder their diets fail! The stricter the diet, the hungrier the dieter, the bigger the backlash. The runner ends up devouring way too much ice cream, too many cookies, chips…

The bottom line: Runners who diet commonly end up heavier. You want to learn how to eat competently by working with a registered dietitian (RD) who specializes in sports nutrition (CSSD).

Is keto the answer?

     So often I hear frustrated runners ask, “What if I just do keto (or Paleo or another trendy diet) for a bit and then go back to eating “normally?” Ha! When runners have managed to successfully lose weight, they can’t go back to eating like they used to eat. These dieters need fewer calories to support their lighter body. For each kilogram (2.2 lb) of weight lost, a dieter requires about 25 fewer calories/kg per day. Hence, runners who lose 10 kg. (22 lbs.) need about 250 fewer calories per day to maintain their new reduced weight. Unfortunately, appetite-regulating hormones nudge them to want to eat more than that. This gets to be a tiring fight, and most folks lose the battle of the bulge.

The bottom line: Preventing weight gain in the first place might be simpler than trying to reclaim a former physique!

Are carbs the problem?

   What if you could lose weight by cutting carbohydrates but not calories? Diet gurus have promised this for years, as do today’s keto supporters. Anti-carbers claim high-carb diets lead to excess insulin secretion, hunger, excessive eating, and fat gain. Low-carb/keto diets are touted to reduce insulin, hunger—and promote easy fat loss.

      Not so simple. Despite popular belief, simply knocking off starches (bread, pasta, grains) and sugary foods does not guarantee fat loss—unless it creates an energy deficit. That is, eliminating a serving of rice from dinner can knock off 200 calories. But does the hungry dieter then indulge in a pint of sugar-free ice cream or a keto-bomb? The carb-free = calorie-free attitude can easily wipe out the deficit created by cutting out carbs.

    Hall’s research does not support the carb-insulin theory that carbs are fattening. He closely monitored subjects in a metabolic ward who ate as much as they desired of high (75%) carb/high-glycemic diet designed to spike blood glucose and trigger high levels of insulin. The subjects did not gain body fat. In fact, every single subject eating the high carb/high insulin/low fat diet ate, on average, about 700 fewer calories/day less than  when they ate the high fat/low carb/low insulin keto diet.  

The bottom line: Carbs are NOT inherently fattening. (If carbs were fattening, then people in Asian countries who eat bowlfuls of rice would be obese. Not the case.)

If carbs aren’t fattening, what is?

      The increase in obesity in the US correlates well with the increased intake of ultra-processed foods. Hall is pointing his finger at foods such as Oreos, soda, instant ramen noodles, chicken nuggets, etc. He has researched the impact of two weeks of an ultra-processed convenience food diet vs. two weeks of a homemade, natural foods diet. The menus were very carefully designed to be equally tasty. The subjects reported no differences in pleasantness between the two diets. They ate as much as desired.

     With the ultra-processed diet, the subjects consumed about 500 more calories a day compared to the unprocessed diet. They gained weight during those two weeks—and lost weight (without trying to do so) with the unprocessed diet. Because both diets offered the same amount of sugar, carbs, and fat, those nutrients did not drive the weight change.

     What’s going on? Hall is currently looking at why ultra-processed foods easily lead to weight gain.

The bottom line: Until we know more, your best bet is to limit ultra-processed foods. Fret less about sugar/carbs, and more about the processing. Somehow, find time to prepare meals. As a parent, please teach your kids to cook. Hopefully you’ll all enjoy the eat-well, stay lean diet!

Most Olympic marathoners spend their youth focused on running. They join track clubs, compete in national championships, and pursue the sport from an early age.

Julia Mayer’s journey was very different.

Today, Mayer is Austria’s marathon record holder, a multiple national record holder on the roads, and an Olympian. Yet for much of her athletic life, running was not her primary sport.

For 16 years, she played soccer.

Then she discovered something that would change her life.

“I noticed that I was really fast in the fun runs and that it was really, really fun,” Mayer said when reflecting on her transition from soccer to distance running.

What began as curiosity quickly became a passion. She eventually made the bold decision to leave soccer behind and focus entirely on running. It was a move that surprised many people around her, but Mayer believed she had found her true athletic calling.

The decision proved to be the right one.

Within a few years, Mayer developed into one of Europe’s top marathon runners. Her steady improvement carried her from local races to the international stage, where she began rewriting Austria’s record books.

She now holds Austrian records in the marathon, half marathon, and road 10K. Her marathon best of 2:26:08 established her as the fastest female marathoner in Austrian history. Her performances in the half marathon and 10K have further cemented her place among the country’s all-time great distance runners.

Her rise culminated with qualification for the 2024 Olympic Games in Paris.

Competing in the Olympic marathon represented the realization of a dream. On one of the most challenging marathon courses ever used for the Olympics, Mayer ran courageously against the strongest field in the world and finished 55th in her Olympic debut.

Behind the scenes, success has come through extraordinary dedication. During marathon preparation, Mayer trains twice a day and covers approximately 200 kilometers, or 124 miles, each week. The workload demands discipline, patience, and a deep commitment to continuous improvement. 

What makes her story especially inspiring is not simply the records or the Olympic appearance.

It is the fact that she found her greatest talent later than many elite runners.

In a sport where athletes are often identified at a young age, Mayer’s journey serves as a reminder that potential does not always reveal itself early. Sometimes it takes years of experience, a willingness to try something new, and the courage to follow a different path. 

The former soccer player who once chased a ball across a field is now chasing history on the roads of Europe.

And according to those closest to her, her best performances may still be ahead.

For runners of every age and ability, Julia Mayer’s story delivers a powerful lesson: it is never too late to discover what you are capable of.

From soccer player to Olympian, her journey proves that remarkable achievements can begin when least expected.

Megan Keith produced the performance of her career in Oslo on Thursday night, shattering one of Scotland’s longest-standing distance running records and cementing her place among Britain’s greatest female 3000m runners.

The 24-year-old clocked a sensational 8:28.35 over 3000m, breaking the Scottish outdoor record that had stood for nearly four decades. In doing so, Keith eclipsed the previous mark of 8:29.02, set by Scottish legend Yvonne Murray back in 1988, ending a record reign that had lasted 38 years.

Keith’s breakthrough run was more than just a national record. The performance also propelled her to third on the UK outdoor all-time list, placing her behind only two of Britain’s most celebrated distance runners — Paula Radcliffe, who leads the rankings with 8:22.20, and Laura Weightman, whose 8:26.07 remains the second-fastest outdoor mark by a British woman.

The significance of Keith’s achievement is amplified by the calibre of athletes she now joins in the record books. For decades, Murray’s mark stood as one of Scottish athletics’ most untouchable records, surviving generations of elite competitors. Keith has now succeeded where many outstanding runners have fallen short, announcing herself as one of the leading distance talents in British athletics.

Her time also compares favourably with the best performances produced indoors. Olympic medallist Laura Muir ran 8:26.41 indoors in Karlsruhe in 2017, underlining just how exceptional Keith’s outdoor effort in Oslo truly was.

The run continues a remarkable rise for the Scottish star, whose progression over recent seasons has transformed her from a promising prospect into a genuine force on the international stage. Running with confidence and composure against elite competition, Keith demonstrated both the speed and endurance required to challenge the very best in Europe and beyond.

With the World Championship season gathering momentum, Keith’s record-breaking display sends a powerful message. Not only has she etched her name into Scottish athletics history, but she has also established herself as a serious contender in one of the sport’s most competitive events.

In Oslo, Megan Keith did far more than break a record. She ended a 38-year wait, climbed into the upper echelon of British distance running, and delivered a performance that may prove to be a defining moment in her career.

British middle-distance talent Phoebe Gill took another significant step forward in her return to top form, producing a determined victory over 800 metres at the Meeting de Marseille in France on Wednesday.

Competing in challenging, wind-affected conditions, the 19-year-old demonstrated both resilience and composure as she held off a late charge from Switzerland's Veronica Vancardo to secure the win in 2:00.81. Vancardo finished just three hundredths of a second behind in 2:00.84, underlining the fiercely contested nature of the race.

While the margin of victory was narrow, the result represented another encouraging milestone for Gill as she continues to rebuild momentum following her injury setback. The young Briton showed impressive race awareness and strength in the closing stages, maintaining her advantage despite the difficult conditions that made fast running a challenge throughout the evening.

The Marseille triumph adds to a growing body of evidence that Gill is steadily progressing toward her best form. Earlier in her comeback campaign, she clocked 2:01.50 for 800m in Bydgoszcz before demonstrating her versatility with a strong 4:05.53 performance over 1500 metres at the BMC Grand Prix meeting in Trafford.

Those performances have highlighted not only her improving fitness but also her ability to compete across multiple distances as she carefully builds her season. The Marseille victory now provides further confirmation that the European junior star is moving in the right direction.

Gill emerged as one of Britain's most exciting middle-distance prospects through a series of breakthrough performances as a teenager, earning widespread recognition for her fearless racing style and remarkable maturity. Injury temporarily interrupted that upward trajectory, but her recent results suggest she is steadily rediscovering the form that made her one of the sport's brightest young talents.

With each race, the signs of progress become increasingly evident. Winning in difficult conditions and under pressure from a quality field is often a stronger indicator than a fast time alone, and Gill's latest success demonstrated exactly those qualities.

As the summer season gathers pace, the Marseille victory offers another confidence boost for the British teenager, whose return continues to gain momentum. If her recent progression is any indication, Gill could soon find herself back among the leading names on the European middle-distance circuit. 

The NCAA Track and Field Championships delivered a moment few could have predicted as Ja’Kobe Tharp produced one of the most astonishing performances in the history of sprint hurdling, rewriting the record books in spectacular fashion.

Competing in the opening round of the men’s 110-meter hurdles, the Auburn star stunned the athletics world by clocking an incredible 12.75 seconds, becoming the first athlete ever to break the 12.80-second barrier. In doing so, he eclipsed the long-standing world record of 12.80 set by Aries Merritt in 2012, a mark that had stood as one of the sport’s most revered achievements for more than a decade.

What makes Tharp’s breakthrough even more remarkable is the scale of his improvement. Entering the championships, the defending NCAA and U.S. champion had recorded a season-best of 13.05 seconds. Yet under the brightest spotlight, he unleashed a performance that exceeded every expectation, slicing an extraordinary 0.26 seconds from his personal best in a race that instantly became one of the greatest ever run.

The achievement sent shockwaves throughout the track and field community. While Tharp arrived in Eugene as one of the leading contenders for the NCAA title, few envisioned a performance capable of redefining the limits of the event. Instead, the American hurdler delivered a race for the ages, combining flawless technique, explosive speed, and impeccable rhythm from the first hurdle to the finish line.

The historic run not only secured his place in athletics history but also transformed the outlook of the championship. With the world record now in his possession, Tharp advances to the final as the overwhelming favorite, carrying momentum that could make an already unforgettable weekend even more extraordinary.

For years, the 12.80 barrier appeared untouchable. On a stunning day at the NCAA Championships, Ja’Kobe Tharp proved otherwise, producing the kind of performance that reminds fans why sport remains so unpredictable. In a matter of seconds, he turned a routine qualifying round into a landmark moment that will be remembered for generations.

The world record no one saw coming is now a reality—and Ja’Kobe Tharp is the man who changed history.

A new chapter in middle-distance running may have begun in Oslo after American teenager Cooper Lutkenhaus produced one of the most remarkable performances of the season, narrowly defeating reigning Olympic champion Emmanuel Wanyonyi in a thrilling men's 800m contest at the Diamond League meeting.

The 17-year-old sensation shocked a world-class field by crossing the finish line first in a race that came down to the smallest of margins. After an intense battle over the final metres, Lutkenhaus held off Wanyonyi by just one hundredth of a second, producing a dramatic finish that left the packed stadium in disbelief.

From the opening lap, the pace was relentless as the leading contenders positioned themselves for a fierce showdown. As the athletes entered the home straight, Wanyonyi appeared poised to unleash his trademark finishing kick. However, Lutkenhaus refused to be intimidated, matching the Olympic champion stride for stride before producing a perfectly timed lean at the line to secure a historic victory.

The result marks a breakthrough moment for the young American, who continues to establish himself as one of the brightest talents in global athletics. Defeating an Olympic champion at a Diamond League event is a feat many athletes spend entire careers pursuing, yet Lutkenhaus achieved it before reaching adulthood.

For Wanyonyi, the narrow defeat does little to diminish his status as one of the world's premier 800m runners. The Kenyan once again demonstrated his exceptional class and competitiveness, pushing the race to a world-class standard and forcing his young rival to deliver the performance of a lifetime.

Beyond the result itself, the race offered a glimpse into what could become one of the sport's most exciting rivalries in the years ahead. With established stars and emerging talents now pushing each other to new heights, the men's 800m continues to evolve into one of athletics' most captivating events.

On a memorable night in Oslo, the spotlight belonged to Cooper Lutkenhaus. At just 17 years old, he stood toe-to-toe with an Olympic champion and emerged victorious, announcing himself to the athletics world in spectacular fashion.
