So skipping breakfast, during a lower calorie intake period, allows you to burn excess fat. Its the way God designed us. When we were huntergatherers and we roamed the earth for the next food supply as nomads, there would be times where the winter would come in and the food supply would drop, or there would be times of famine where there just wasnt a food supply. God was smart enough to design us with a source of sugar during these times of need for food. All mammals have this food storage system called fat. When you see those commercials asking to aid children starving in other countries, those children are relying on these fat stores to survive their lack of adequate nutrients. God and evolution also designed us to HEALTHILY use up this fat store when we dont have enough food. Fasting is how we were designed to use up our fat, so anyone who tells you weight loss through fasting is unhealthy has an argument with the Big Guy who designed this survival system. Through time the human body has adapted to using fat for food storage to allow survival through times of famine or starvation. If it was unhealthy, the system wouldnt exist as it came to be through evolution and nature. The fittest survive, and those with fat storage systems survived longer when there is no food. Well here is how this system got bastardized. After we went through the ice age and became agrarian in our economy, an abundant food supply existed. We didnt starve anymore, and we dont starve anymore because right now we have plenty of farms and excess food stores to supply us with nourishment.
