Weighty issue: Stress and high-fat meals combine to slow metabolism in women

A new study in women suggests that experiencing one or more stressful events the day before eating a single high-fat meal can slow the body’s metabolism, potentially contributing to weight gain.

Researchers questioned study participants about the previous day’s stressors before giving them a meal consisting of 930 calories and 60 grams of fat. The scientists then measured their metabolic rate — how long it took the women to burn calories and fat — and took measures of blood sugar, triglycerides, insulin and the stress hormone cortisol.

On average, the women in the study who reported one or more stressors during the previous 24 hours burned 104 fewer calories than nonstressed women in the seven hours after eating the high-fat meal — a difference that could result in weight gain of almost 11 pounds in one year.
