Here is very useful data as to food consumption patterns. Nowadays we ruin our body with unnatural eating cycles.
Basically fasting for around 16 hours a day is good for health. From the evolutionary perspective--that invested in a human body 200K years--the way we eat today is broken. And our body can't adapt to a new pattern--evolution is a slow process that requires many thousands of years. Not to mention like adapting to changes in a food consumption we see in the last 50 years. A human body during 200K years of evolution was not prepared to eating a lot. Viceversa--it was build to eat less. It needs to store energy and to use stored energy and only after that to store again. That's a natural cycle and functions that our body needs to execute. Nowadays we just store energy 24/7:
"Emerging findings from studies of animal models and human subjects suggest that intermittent energy restriction periods of as little as 16 h can improve health indicators and counteract disease processes. The mechanisms involve a metabolic shift to fat metabolism and ketone production, and stimulation of adaptive cellular stress responses that prevent and repair molecular damage."

Here are also interesting patterns of daily and weekly food consumption from this research including the common eating pattern of food consumption upon which the epidemic of obesity, diabetes, and associated chronic diseases has emerged.
