yep this is true, but it is much better to eat 5 small meals than 1 massive one.
When you stuff yourself with too much food in one sitting then it takes a lot more energy for your body to digest the food. This saps the energy and all we feel like doing is going and sleeping.
Also eating foods that are easier to consume again will keep energy levels up.
My current diet regime and philosophy....
Eat a healthy diet. A tuna salad takes less energy to digest than a steak.
Have more energy, eat right. Drink more water. Water increases energy, flushes toxins and controls metabolism to help lose weight. 10-20 minute run/sprint every day.
