Surgical processes such as a gastric bypass allows a team of trained professionals to shrink the overall size of the stomach. This provides people with the sensation of being full much quicker than normal due to the smaller stomach size. Overall, this process can lead to very fast weight loss but also involves surgery and the possible complications any surgery can present. Without the proper nutrition following the surgery through a nutritionally dense diet, one may become deficient in several valuable vitamins and minerals. Due to the lack of food entering the body, the food sources must contain the proper amounts of the necessities that the body needs to function. Other surgical processes involve the removal of fatty tissue. In extreme cases, people who are morbidly obese may endure very fast weight loss, losing 200 to 300 pounds during a surgery. For those seeking simple, quick fast loss of a mere 20 to 30 pounds, surgical processes are usually not the best option.

A low calorie diet paired with exercise, including cardiovascular and anaerobic types,  can provide weight loss results in a matter of weeks. This method provides a healthy and natural alternative to surgery. By losing or burning calories through exercise, the body first sheds its fatty tissue. Building lean muscle while incorporating weight loss exercises will result in a toned slender core. Another method that could be paired with this natural process is the use of supplements. The healthy and fitness industry continues to invent new products targeted directly at fast weight loss, due to the high demand by people everywhere. These supplements often target fatty tissue by means of burning calories while the body is sedentary, though most work far better with the implementation of steady exercise and a healthy diet. One should always consult with their doctor before partaking in the use of any supplements and/or exercise program.
