Heavier people can lose larger amounts of weight in the same amount of time while staying healthy. Reducing salt intake can result in a larger initial loss due to a loss of water weight. Limiting starch intake also helps lessen fluid retention. Together, limiting these two things can result in up to 5 pounds of lost weight.

To create this deficit, a person must eat fewer calories than his maintenance level while retaining the same amount of physical activity, or eat at maintenance levels while increasing physical activity. For example, a 200-pound person can burn over 500 calories in an hour by bicycling at 12 miles per hour.

Alternatively, mix and match by consuming fewer calories and exercising more to get the benefits of both styles of weight loss. Increased water and vegetable intake help a person feel full, which makes it easier to create a calorie deficit without feeling hungry.
