The Claim
In adults with obesity and abnormal glucose metabolism, a standardized low-fat diet results in a significantly greater reduction in resting energy expenditure over six months compared to a personalized glycemic-targeted diet, with a mean difference of 92.3 kcal/day (95% CI 0.9–183.8, P=0.05).
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.
Among adults with obesity and impaired glucose metabolism, a standardized low-fat diet causes a larger decrease in resting energy expenditure after six months than a personalized diet targeting blood sugar levels, with a measured difference of 92.3 kcal per day.
See the scientific wording
In adults with obesity and abnormal glucose metabolism, a standardized low-fat diet leads to a significantly greater reduction in resting energy expenditure over six months compared to a personalized glycemic-targeted diet (difference 92.3 kcal/day, 95% CI 0.9–183.8, P=0.05), suggesting that metabolic adaptation may differ between dietary approaches despite similar weight loss.
Eating a low-fat diet for months lowers the body's ability to burn calories at rest because it reduces the activity of fat-burning pathways in muscle and liver, and decreases the signals that tell the body to generate heat, even when weight loss is the same as with other diets.
What the research says
1 studyPeople on a standard low-fat diet burned slightly fewer calories at rest after six months than those on a personalized diet, even though both lost similar amounts of weight. This suggests the low-fat diet may slow down metabolism more.
