If you are trying to gain weight, try not to skip meals. You can still gain weight by simply eating more calories than you burn for the entire day.
On the other hand if you are attempting weight loss or simply desire to maintain your weight, many health professionals believe skipping meals regularly gives you the opposite effect - you have a greater chance of gaining weight. While this may be true for some, it may not be for others but consistency is the key when it comes to weight control whether you are trying to lose or gain weight. The key to success in both areas is to know the total daily calories that allow you to reach your goal. Divide them into 4-5 small meals and spread your meals evenly throughout the day to keep your energy levels high and stave off hunger. To make sure you stay on goal, use the dotFIT program. You can set your goals and create the ideal program including individualized menus, proper calorie and protein requirements, meal timing, exercises that you choose to perform, and coaching/feedback all the way till you reach your goal.
