Athletes who cannot lose weight have a problem with their diet.

A new study from Harvard researchers suggests that they’re actually the ones who are most likely to be suffering from weight-related issues.

The study also found that the average weight loss in the study was only 20 percent of the athlete’s body weight, making it one of the lowest reported results in the literature.

The findings are in the Journal of Obesity, and are the latest to raise questions about the effectiveness of diet and exercise programs.

In an email to Recode, the Harvard researchers explain that their study was limited in scope, and that they were unable to determine whether the athlete was obese or underweight.

But they did find that the athletes who could not lose weight experienced an increase in their weight.

Researchers compared the weight of participants who were able to lose body weight to those who could lose weight without dieting.

The results showed that the group who were unable or unwilling to lose the same amount of weight did not experience the same weight gain.

That’s a problem because weight loss can have a negative impact on a person’s health.

One study from the University of Minnesota found that obese women who lost 10 percent of their body weight gained 10 percent more fat than those who lost the same number of pounds.

Researchers said this was a result of being able to maintain their body mass index, which is calculated by dividing the person’s weight in kilograms by their height in meters squared.

“Our study suggests that weight loss is a critical part of the weight loss program,” lead author and psychologist Katherine A. Smith said in a press release.

“It’s the number one factor for weight loss, so we wanted to know if this was true for people who have trouble losing weight.”

This is important because, in addition to the risk of heart disease, the researchers found that individuals who were underweight or overweight had an increased risk of diabetes, high blood pressure, high cholesterol and type 2 diabetes.

The Harvard researchers also said that this study provides further evidence of the need to increase efforts to reduce the amount of body fat in individuals.

In other words, the more you can shed, the less you’ll need to eat.

If you want to lose some body fat, there’s still time to start the process.

You’ll need a program to help you lose weight for a few months, and then a diet that includes plenty of vegetables, fruits and lean proteins.

You should also follow a program of aerobic exercise to lose fat, as it’s known to be an important factor in weight loss.

But this is a step in the right direction, researchers said.

“These findings suggest that diet, exercise, and social support may help athletes reduce their body fat without having to restrict food,” Smith said.
