Dietary restriction

- Caloric restriction
- Intermittent fasting
- Time-restricted feeding
- Fasting-mimicking diet
- Periodic fasting
- Protein restriction
- Methionine restriction
Human trials show dietary restriction regimens reduce body weight and fat mass, but one trial reports induced respiratory sarcopenia. In mice, caloric restriction lowers blood glucose but increases cholesterol and atherosclerosis in ApoE-deficient models.
