Exercise as a predictor

Exercise is the best predictor of long-term weight maintenance in the post-surgical patient. Once cleared by your surgeon, it is imperative that you begin a comprehensive exercise program immediately. During the period of rapid weight loss directly following your surgery, you will lose a considerable amount of muscle mass if you are not exercising. This muscle loss negatively affects your metabolism, impeding further weight loss, and maintenance of your current weight.

Your body weight should begin to stabilize within 18-24 months post surgery, as your body reaches homeostasis. This is when the patient is at risk of regaining weight. The stomach is becoming more tolerant of certain foods and can handle a larger capacity; physical activity is essential for further weight loss. With bariatric surgery comes the responsibility of embracing a new way of eating, a new physically active lifestyle, and most importantly a new you!

A comprehensive exercise program includes cardiovascular exercise, resistance training and stretching - each with their own objectives and benefits for the body.

  • Cardiovascular Exercise: any activity that requires an increased use of oxygen by the body. It necessitates the use of large muscles at a moderate level of intensity for an extended amount of time. Examples include walking/running, biking, swimming, etc. The purpose of cardiovascular exercise is to increase strength and functioning of the heart and lungs, thus improving circulation and aerobic capacity. It is also the most efficient form of exercise for depleting fat stores.
  • Resistance Training: contracting a muscle against external resistance (ex. dumbbell, circuit machines, body weight). The purpose of resistance training is to increase muscle mass, strength and endurance and to improve bone density. Post-operatively, resistance training is extremely important in maintaining your muscle mass and metabolism.
  • Stretching: deliberately elongating a muscle to its fullest length. The purpose of this type of exercise is to improve elasticity of the muscle and to increase flexibility and range of motion of the joint.


To make the most of your exercise efforts you must consume an adequate amount of protein, approximately 60 grams a day. Protein is the structural basis of many tissues in the body, most importantly muscle. Without appropriate amounts of protein, the body lacks the tools it needs to repair and build muscle fibers. Protein intake is your No. 1 priority. Consult with your surgeon or a nutritionist on the best way to ensure appropriate levels of protein in your diet.

The biggest challenge in beginning an exercise program is consistency. You must make physical activity a habit, a part of your daily life. You are doing this for you. Not because your husband or wife wants you to, or your doctor is instructing you to. This is a decision you have to make for yourself. You must find activities or classes that you enjoy and will not dread. Find a workout partner or join a gym with like-minded members to keep you motivated. The physical and mental benefits of exercise are endless and well worth the effort.
