If elite male cyclists eat a super high-fat diet for six days and then carb-load for one day, they’ll perform worse in sprints—even though they don’t feel more tired, their heart rate doesn’t change,...
If male cyclists eat a super high-fat diet for six days, their body's 'fight or flight' system might get a bit more active — and that change doesn’t go away right after they start eating carbs again.
If a male cyclist eats a super high-fat diet for 6 days and then loads up on carbs for 1 day, it won’t slow them down in a 100-km race compared to eating lots of carbs all along.
If elite male cyclists eat a super high-fat diet for six days, their bodies get better at burning fat for fuel — even when they switch back to eating lots of carbs for a day.
If elite male cyclists eat a super high-fat diet for 6 days before carb-loading for a day, they’ll feel just as fast over a long 100-km ride — but they’ll have less power for short, intense sprints...
Elite race walkers who follow a keto diet for 3 weeks start burning fat for fuel during intense exercise, and their bodies show signs of ketosis — like having 1 mmol/L of ketones in the blood — even...
Elite race walkers who eat lots of carbs or time their carb intake during intense training get about 5-6% faster in a 10 km race, but those on a keto diet don’t get any faster.
Even if elite race walkers don't change their diet, their stamina can still improve after a few weeks of intense training, as long as they're eating enough calories.
Even though elite race walkers get better at using oxygen overall on a keto diet, the diet makes their bodies use more oxygen during race pace, so their performance doesn’t actually improve after 3...
Elite race walkers who eat a super low-carb, high-fat diet for 3 weeks start burning fat like crazy when they exercise — one of the highest fat-burning rates ever seen in top athletes.
If untrained guys eat a high-fat diet for 7 weeks, their muscles use less stored sugar during medium-intensity exercise compared to eating a high-carb diet — it’s like saving their fuel — but their...
If untrained guys eat a high-fat diet for 7 weeks, they burn more fat during exercise than if they eat a high-carb diet.
If untrained guys eat a high-fat diet for 7 weeks, their bodies get better at burning fat from the blood during exercise compared to eating a high-carb diet.
For endurance athletes, switching to a high-fat diet for six days and then loading up on carbs doesn’t seem to boost performance in a one-hour cycling test compared to sticking with a high-carb diet.
Even after endurance athletes eat lots of carbs for a day, their bodies still burn more fat than usual if they recently spent a week on a high-fat diet.
When endurance athletes eat a high-fat diet for 6 days, their bodies burn less carbs during a long bike ride compared to when they eat a high-carb diet — showing their metabolism switches to using...
If endurance athletes eat a high-fat, low-carb diet for just 6 days, their bodies burn way more fat during a long bike ride — about 50 grams more over 4 hours — compared to when they eat lots of...
When these lab mice are exposed to a chemical called BDE-47, it might slow down their liver's ability to burn fat, leading to fat buildup that could cause a type of liver disease.
In these lab mice, a chemical called BDE-47 turns up a protein that pulls more fat into the liver, which can lead to fatty liver disease.
In mice, being exposed to a chemical called BDE-47 might cause their livers to store more fat and not burn it properly, leading to fatty liver and signs of liver damage — a possible early sign of a...
Probiotics might help with weight loss by changing how your body burns energy, turning certain genes on or off, and shifting the balance of gut bacteria—like boosting good bacteria (Bacteroidetes)...
Taking a mix of good bacteria and fiber every day for three months might help obese women eat less and feel better about their bodies, leading to weight loss.
Taking a probiotic called Bifidobacterium breve B-3 daily for three months might help reduce body fat and improve cholesterol levels in people who are slightly overweight.
Taking a mix of good bacteria for six weeks might help lower bad cholesterol and inflammation while improving good cholesterol and blood sugar control, especially if also taking fish oil.
