The notion of eating “three square meals” a day is old school. The fundamental problem with this concept is that too much time elapses between feedings. This means that our metabolism (the rate and efficacy in which we utilize calories) is not optimized, and also that we tend to eat more than we can optimally digest at one sitting because we allow ourselves to get too hungry.
The Rock-Solid way to optimizing our food intake is to eat smaller, plant-based meals or snacks, at least five or six times day. One of the common mental barriers to this idea of eating so often lies with those folks who are either trying to lose weight or are afraid of gaining weight. This is one of the great paradoxes of weight loss.
When you go too long between eating, and/or you don’t get enough calories each day, your body can kick into a sort of trauma mode and actually hang on to your existing fat reserves. Why? Because as it recognizes that there is not an optimal amount of fuel coming in from the outside, it attempts to conserve all of the stored fuel (fat) from the inside. So not only does this multiple meals and snacks concept increase your metabolism, but it also creates a more secure environment for your body to let go of the fat, provided, of course, that your total daily caloric intake does not exceed the amount that you burn.
