Keeping your skin tight during weight loss can be accomplished by taking your time to lose the weight and exercising. A complete weight-loss program includes a healthy diet and a full-body strength-training workout regimen. Providing your body with nutrients, vitamins and water can also help maintain your skin's elasticity as the weight comes off, while exercise increases muscle tone.
Lose weight slowly. Losing a lot of weight in a short period of time does not give the skin enough time to shrink. The American College of Sports Medicine recommends losing no more than 2 pounds per week.
Maintain the elasticity of your skin during weight loss. Vitamin A, which is found in green leafy vegetables, whole milk and liver, can help maintain and repair skin. Fill your diet with plenty of vegetables and fruits to maximize your intake of vitamins and minerals.
Drink plenty of water to stay hydrated. The hydration level of the skin is one of the most important factors that influences skin elasticity.
Perform strength and resistance exercises. Using either body-weight, free-weight or equipment assisted exercises, give your body a full workout three times a week, on non-consecutive days to build muscle and give definition to your body as you lose the fat.
Avoid smoking and drinking. Cigarette smoking causes biochemical changes in the body that accelerate aging, and as you age, your skin loses elasticity, according to Aging Skin Net.
