Probably. For four to six hours after you finish eating a meal, your body produces a lot of energy to help digest, absorb and process the food. This extra energy produces heat and uses up extra calories that otherwise may have ended up stored in your body as fat. When you exercise, your body produces extra heat because more than 70 percent of the energy use to power your muscles is lost as heat. Your temperature continues to stay elevated and you to burn more calories for several hours after you finish excising.
If you are active after you eat, your body burns more calories than if you are inactive after you eat, so most people are far more active after they eat breakfast than after eating supper and therefore the food that you eat in the morning is less fattening than what you eat in the evening
