The Mayo Clinic advises a person trying to lose weight quickly to follow a diet and exercise program where he aims to lose 1 to 2 pounds per week by burning 500 calories more per day than he consumes. Such a diet involves replacing high-calorie food with lower-calorie alternatives and increasing daily activity.
As WebMD explains, rapid weight loss plans emphasize lean meats, vegetables and fish over saturated fats, sugars and starch. WebMD also encourages dieters to remain hydrated. Reducing salt intake reduces water weight temporarily although it does not decrease body fat.
Instead of embarking on a full diet plan, Health.com suggests small tweaks to daily activity that can help people lose weight quickly. The advice includes eating a full breakfast, adding in a few minutes of isometric exercises when possible, throwing away unhealthy foods, listening to more energetic music while exercising, trying new exercises like Zumba or yoga and ordering smaller portions when eating out.
WebMD suggests dieters maintain a food diary to keep track of food and exercise while also recording what circumstances and emotions increase or decrease unhealthy behaviors. According to the Mayo Clinic, losing any more than 1 to 2 pounds per week is dangerous and discouraged unless specifically prescribed by a physician.
