The Claim

Among obese adults in a behavioral weight loss program, there is no significant difference in energy intake between individuals who lost less than 5% of their body weight and those who lost 10% or more, and differences in physical activity levels explain the variation in weight loss outcomes.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In obese adults undergoing behavioral weight loss, those who lost more weight did not eat significantly different amounts than those who lost less weight; the difference in weight loss was explained by differences in physical activity levels.

See the scientific wording

Among obese adults in a behavioral weight loss program, energy intake did not differ significantly between those who lost less than 5% and those who lost 10% or more of their body weight, suggesting that differences in physical activity, not diet, explain the variation in weight loss outcomes.

Why this might work

People who lose more weight move more throughout the day, especially with brisk walking, which burns more calories and forces the body to break down fat for fuel, even when they eat the same amount as those who lose less weight.

  1. Study: Pattern of Daily Steps is Associated with Weight Loss: Secondary Analysis from the Step-Up Randomized Trial

    People who lost the most weight walked a lot more each day, especially in longer, brisk walks, even though everyone ate about the same amount. So it wasn’t what they ate—it was how much they moved—that made the difference.
