Step 1

Follow a reduced calorie diet. "Handbook of Obesity Treatment" suggests meeting with a registered dietitian to learn how many calories you should be eating daily for optimal weight loss. However, if you are unable to meet with a dietitian, the general rule of thumb is that men should consume 1,800 calories per day for weight loss and women should consume 1,200 calories per day for weight loss, according to "Foundations of Nursing."

Step 2

Perform cardiovascular exercise, such as walking, swimming or biking, for at least 20 minutes at least three days per week. According to "Handbook of Obesity Treatment," cardiovascular activity is key to initial weight loss because it increases immediate calorie expenditure.

Step 3

Perform strength training exercise for at least 20 minutes at least three days per week. Strength training exercises include using weight machines, performing calisthenic exercises and using dumbbells. According to "Handbook of Obesity Treatment," strength training is an essential part of maximizing weight loss because it builds muscle mass, which naturally increases your basal metabolic rate and leads to greater calorie expenditure while resting.
