A carefully selected diet is important to successfully manage excessive weight. A diet low in animal fat will help.
The diet should be modified to maintain appropriate nutrition while decreasing calorie intake. A daily multiple vitamin and mineral supplement is recommended. Design a weight-reduction diet such as the following:
― Determine the estimated number of calories estimated to be needed to maintain weight based on gender, age, height, weight, and activity level.
― Choose an intake of 500-1000 calories LESS than the one estimated to maintain your current weight (but not less than a total of 1000 calories per day).
― Use your chosen daily calorie intake to determine the servings in each food group.
― Distribute these servings over 5 to 6 meals throughout waking hours.
Use low-calorie snacks to stave off hunger, such as yogurt (80-100 calories) plus a glass of water.
Strictly maintain the size and number of servings each day. Consider and treat edema and hormonal imbalances, if present. These are uncommon and most persons with excess weight can benefit from calorie management.
