Surprising Findings
Benefits faded over time despite continued restriction
It contradicts the common belief that sustained dieting leads to lasting health improvements—here, the body adapts and reverts.
Practical Takeaways
Consider moderate caloric restriction (e.g., 15% reduction) for short-term metabolic and reproductive health boosts, but don't expect it to last indefinitely.

Researchers found that when they put middle-aged male rats on a diet with 15% or 35% fewer calories, it helped their reproductive health at first. But after a year on the diet, these benefits went away, and only one-third of the dieting rats still showed normal mating behavior compared to all of them at six months.
Eating less food for six months helped older male rats have better sex lives by making them mount and mate faster and ejaculate more often, compared to rats that could eat as much as they wanted.
When rats eat less food for several months, their testosterone levels go up compared to rats that eat normally.
When older male rats eat less food for several months, their bodies process sugar better and have healthier hormone levels.
When male rats ate less food for several months, their testicles showed fewer signs of cell death compared to rats that ate normally. This was measured using a special light test that detects dying cells.
