Burn more than you eat and your weight will drop. “However, this equation can be deceptively simple because it doesn’t take into account the multitude of factors that affect what we eat, how much we exercise, and how our bodies process all this energy,” say experts from the TH Chan School at the University of Harvard. of Public Health. “The causes of obesity are as varied as the people they affect,” they write, noting that “inheritance is not destiny” when it comes to weight and health.

The study analyzed data collected from 16 subjects with a BMI considered overweight or obesity while following a couple of strictly scheduled meal plans. Although the diets in these two meal plans were identical in nutritional content, participants were first instructed to eat one hour earlier and then instructed to eat four hours after that initial time.

The participants self-reported their changes in appetite, and the researchers collected blood samples, measured their energy expenditure, took their body temperature, and collected samples of fat tissue to compare any changes in gene expression from one eating plan to the next. “The order of the protocols was randomized and the visits were separated by a washout period of three to 12 weeks,” the study explains.
