It is a well-established fact that calories control everyone's bodyweight. No matter how many meals a day you have, it is
calorie balance in end of day that matters. If you eat fewer calories than you are burning, you will lose weight. It won't matter if these calories come from chocolate, bagels, meat, eggs, fruit or whatever else.
Calories control bodyweight.
What about body composition? The two major components of body composition are lean body mass and fat mass. Suppose you just lost 10 pounds of bodyweight. Does it matter how many of those 10 pounds were fat and how many muscle? Sure, it DOES matter. While calorie balance controls bodyweight, other important factors influence proportions of fat and muscle that you gain or lose! These factors may improve or make worse way you look naked.
One of those factors is calorie distribution (or calorie fragmentation). Bodybuilders, as group of people most concerned with their body composition, have been spreading their calorie intake into smaller and more frequent meals for decades. Originally they believed that doing so "raises one's metabolism". Science has never proved this belief. Recent findings reveal that there is no metabolic advantage of eating smaller and more frequent meals.
However recent research has uncovered that spreading your calorie intake into smaller and more frequent meals improves body composition! More calories end up building muscles, and less calories go to your fat deposits. The calorie balance equation still rules, but more calories end up building muscles! That, my friend, means that you will look better!
