In accordance with the metabolic needs of our body and, as well as for the proper secretion of hormones and the stimulation of the enzyme for the breaking down fat, breakfast must not be skipped .Best time for breakfast is between 8 and 9 o’clock in the morning. In this way, the body begins proper consumption of fat reserves in the body, and with this morning stimulation spending of fat in the body takes place throughout the day. If you skip breakfast or the first meal postpone until the afternoon hours, the body creates a defense mechanism, and then the fat, instead of being exploited as a major source of energy for all organs (heart, lungs, brain, muscles …), deposit, settle and preserve for „a rainy day“. The body is in „fear“ of running out of food, and instead breaking down fat begins to break down the proteins. In a restrictive diets for a „quick“ weight loss, diets to reduce the number of meals and amount of food, weight loss is only illusion. Therefore, with the termination of the diet and re-entering food in the same amount and composition as before diet, weight is quickly gaining back, which is known as the Yo-Yo effect. Breakfast has to be balanced. It should contain enough calories to meet the needs of the organism.
