Energy Input = Energy Output

Consuming more energy than the amount of energy you use will result in weight gain.

Energy input should approximately equal energy output.

One of the best ways to maintain a healthy and balanced diet is to match the amount of energy gained from food consumed to the amount of energy that your body will use up. If energy input is greater than energy output, it will result in weight gain. However, if energy output is greater than energy input, it will result in weight loss. Balancing energy input and energy output will help you maintain the perfect body weight.
