A person who skips breakfast puts their body in starvation mode so that any excess food that you eat later in the day instantly becomes fat as the body scrambles to keep any sugar available in the body after being told its starving when breakfast is skipped. However, if you skip breakfast, and then take in small amounts of food for lunch and dinner, lower amounts of calories than is needed for a full day, you WILL BURN FAT to make up for energy that you dont have coming in from food. So skipping breakfast, during a lower calorie intake period, allows you to burn excess fat.
