There are charts to look up you ideal weight, but you can calculate your ideal body weight using the body mass index. Body mass index is calculated from height and weight. If you meet the BMI guidelines you are at your ideal body weight. BMI should be about 23. To find your ideal weight, use a BMI of 23.
Variation occurs in the ideal weight based on body build.
Maintaining an ideal body weight by moderation in total food intake, while following the recommended balance of food components, is still the best and safest means of achieving a healthy life style for diving. When you perform a greater amount of work, you can compensate by increasing food intake to obtain additional energy. To be ready for the demands of diving, you should add an exercise program to your nutritional program. A rough rule of thumb is that a mile traveled on foot consumes about 100 calories of energy regardless of the time it takes. So a two-mile walk will account for most of the calories in your breakfast.
