Cutting calories by 40% did not stop mice from running every day. According to the authors of the publication in the journal, this means that for humans, diet is not a reason to give up sports and daily activity Physiology and Behavior.
In the first week of the experiment, scientists gave the mice a normal amount of food, in the second week the amount of calories was reduced by 20%, and in the third week by 40%. The study included normal mice and mice that love to run. The animals did not reduce their daily distance on the running wheel in either the first or second week.
“We don’t want dieters to stop exercising because they don’t feel they have enough energy. That would be counterproductive, and we now know it doesn’t have to be that way,” the scientists said.
Mice surprised scientists by losing just 4% of their body weight despite a 40% calorie restriction. A similar phenomenon has been seen in humans. Now scientists plan to find out exactly what prevents you from losing weight on a strict diet. It likely involves the same compensatory mechanism that allows mice to stay active when calories are restricted.
“Like our mice, humans typically lose about 4% of their body weight when they diet. If you reduce your food intake by 40% and your weight doesn’t fall less than expected, there must be some compensation. This could be a decrease in activity or an increase in metabolic efficiency,” the authors explained.
