There are studies show a calorie-restricted diet may slow aging in healthy adults. But can we simply and safely say eat less, live longer? I believe there is distance away. However, in general, that’s the case (for most people living in the developed countries).
This study is based on 220 adults some cutting as much as 25% or 500 calories of 2,000 calories daily diet and some don’t over 24 weeks. By measuring certain DNA biomarkers in the blood over time, the researchers can measure the rate of aging. The researchers found that people who cut their calories slowed the pace of their aging by 2% to 3%, compared to people who were on a normal diet.
One may
argue if a person cannot fully enjoy the life and live happy, what’s the point
of living longer. However, that is not the point of the study. Over the course,
human have studied the aging and are able to accelerate the process in lab mice, even have some success in reversing the aging. To be ale to apply on human, that could be another decade
away. For now, it is clear over-eating is as bad as over-drinking alcohol.
Another arguable aspect is the calorie. This is not a good indicator for nuitrition intake. But that should be another blog or blogs to elabrate that. Before than, you may want to read Gary's book below. Enjoy!
