Stress and High-Fat Meals Can Slow Down Metabolism in Women

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

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. The stressed women also had higher levels of insulin, which contributes to the storage of fat, and less fat oxidation — the conversion of large fat molecules into smaller molecules that can be used as fuel. Fat that is not burned is stored.
