After weight training, young women had a slightly higher resting calorie burn, but this was entirely due to gaining muscle — the training itself didn’t make their metabolism more efficient. This...
After six months of either cardio or weight training, young women did not burn more calories per day overall — the extra calories burned during workouts were not offset by higher resting or daily...
After six months of weight training, young women gained about 1.3 kg of muscle and became stronger, but their total daily calorie burn did not increase. This finding is from the abstract summary -...
After six months of regular aerobic exercise like running or cycling, young women who were not overweight became significantly better at using oxygen during exercise, but their body fat and muscle...
Doing a moderate amount of aerobic exercise—enough to burn about 8 calories per kilogram of body weight each week—doesn’t cause weight loss or noticeable changes in how many calories the body burns...
When obese adults do a lot of aerobic exercise, they don’t eat significantly more food, so the reason they lose less weight than expected is likely because their bodies burn fewer calories during...
When obese adults do a lot of aerobic exercise, they move less while confined in a lab chamber, but their everyday movement—like walking around the house or standing—doesn’t change, meaning the lab...
Humans evolved to be active throughout life, and being inactive now causes our bodies to age faster and become more prone to disease because the systems that repair damage only turn on when we move...
The idea that your body lowers its resting metabolism to compensate for exercise is not backed by solid science — most evidence for it comes from flawed statistical methods, not real biological...
Exercise helps prevent disease not just by burning calories, but by shifting the body’s energy use away from processes like hormone production that can increase cancer risk, and toward repairing...
Humans burn more energy at rest and during activity than other mammals of similar size, not because we move more, but because our bodies are built to invest more energy in keeping ourselves healthy...
People who are more physically active burn more total energy each day, and their bodies do not lower their resting energy use to compensate — meaning activity directly adds to overall energy...
Athletes move for about 13 hours a day outside of training and sleep—160 minutes less than non-athletes—but they move more intensely during that time, burning more total energy despite less total...
For male college athletes, everyday movements like walking to class or standing during lectures burn nearly as much energy as their actual sports training, meaning their total calorie needs are much...
Even though athletes and non-athletes burn about the same amount of energy per kilogram of body weight over a full day, athletes pack that energy use into fewer hours, meaning they move more...
College athletes spend less time sitting or doing light tasks like browsing phones, and more time doing brisk walking or other vigorous movements during their free time, making their daily movement...
Male college athletes burn more total energy through everyday movements like walking and standing than non-athlete students, but when adjusted for body size, their activity levels per kilogram of...
Losing weight through diet or exercise for 12 weeks did not cause measurable changes in hunger hormones or how much people ate when given free access to food, indicating that the body doesn’t...
After losing weight through diet or exercise, the body’s resting energy use doesn’t drop more than expected based on how much fat and muscle were lost, meaning the body doesn’t significantly slow...
People who lose weight by eating less tend to feel less hungry over time, while those who lose weight by exercising tend to eat less impulsively, but these changes were not significantly different...
When adults with obesity lose weight, those who exercise regularly tend to keep more muscle than those who only reduce calories, though the difference in muscle loss between the two groups was not...
For adults with obesity, losing weight through 12 weeks of regular exercise or reducing calorie intake led to about the same amount of weight and fat loss, indicating that the method of creating a...
When obese adults do a lot of aerobic exercise, their overall activity level goes up, and they burn more calories during exercise—but their resting metabolism, sleep energy use, and digestion-related...
When obese adults do a lot of aerobic exercise, they don’t eat significantly more—even though they’re burning more calories and losing weight—so overeating isn’t the main reason they lose less weight...
