Is calorie restriction good for longevity?
Restricting calories but making food available around the clock extended their lives only 10% to 875 days despite restricting calories by 30-40%. Restricting this reduced-calorie diet to the inactive period of the circadian cycle boosted lifespan by nearly 20% to an average of 959 days.

A starvation diet doesn’t promote weight loss because your metabolism slows down in response to low caloric intake.
Does eating less make you live longer?
Eating fewer calories may slow down aging and increase longevity. Eating less may lengthen your life. Researchers have increased life-spans in yeast and mice by having them consume fewer calories per day, and ongoing studies suggest that a strict low-calorie diet may slow aging in primates, too.

Do slow eaters live longer?
Those who take their time over meals i.e. eat more slowly have a higher life expectancy.
Does a slow metabolism make you live longer?
That is, metabolic rate is thought to be inversely proportional to maximum lifespan, which means that species that live fast will die young while those that have a slower metabolic rate live slower and longer.
What kind of fasting is best for longevity?
Researchers analyzed hundreds of studies to identify a diet that optimizes human health and longevity. They found that diets low in animal protein and high in complex carbohydrates that include periods of fasting are most beneficial for long-term health and life span.
Does fasting increase your lifespan?
Among the four eating schedules, only iTRF significantly extended the lifespan—18% for females and 13% for males. And the timing of the 20-hour fast was critical: Lifespan increased only for flies that fasted at night and broke their fast around lunchtime.
