The Claim
In aging mice undergoing ad libitum refeeding after caloric restriction, total energy intake is strongly correlated with weight regain (r = 0.95, p < 0.001), and caloric consumption is the primary driver of body mass increase, independent of macronutrient composition.
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.
In older mice that are allowed to eat freely after a period of reduced calories, the amount of food they consume directly determines how much weight they regain, more than the types of nutrients in their diet.
See the scientific wording
During ad libitum refeeding after caloric restriction in aging mice, energy intake is strongly correlated with weight regain (r = 0.95, p < 0.001), indicating that total caloric consumption, rather than macronutrient composition alone, is the primary driver of body mass increase.
When food becomes freely available after a period of eating less, the body takes in far more calories than it needs. The extra calories, especially from fat, trigger the brain to keep eating even when the body has enough energy stored. This causes fat cells to grow larger and multiply, and the body stores the surplus as fat instead of burning it off, leading to rapid weight gain.
What the research says
1 studyWhen older mice ate less and then got to eat as much as they wanted, the ones that ate the most calories gained the most weight back—no matter if those calories came from fat, carbs, or protein. The more they ate, the more weight they regained.
