I have heard here and there that instead of consuming 3 largish meals (the traditional 3 meals a day), that consuming several smaller meals throughout the day is beneficial for health (and weight loss).
How true is this statement? What are the biological advantages, if any, of such a diet?
One rationale is that smaller meals will cause less insulin secretion compared to a larger meal. With less circulating insulin over the time, insulin will be under the threshold required to activate the adipogenic program in the white adipose tissue. So, you will burn ingested carbohydrates instead of converting them in fat despite the same caloric intake. See for instance Munster and Saris, Plos One 2012.
