Zone

• The Zone diet works because it involves fueling your body with the nutrients it needs to be in the weight loss "zone." The diet provides scientific facts that prove that subtle changes in your diet affect hormonal communication. This communication must be re-established for weight loss to occur. This is accomplished by eating protein at every meal, monitoring carbohydrate intake and dramatically reducing consumption of Omega-6 fatty acids. Protein at every meal will keep you feeling full all day, which will limit cheating and splurging. Carbohydrates are still necessary but should be monitored to ensure that your insulin levels are not too high nor too low. Limiting fatty acid intake will reduce inflammation. These three steps combined make up the Zone diet.
  
  

Jenny Craig

• The Jenny Craig Weight Loss Program will design a personalized program around your eating style, weight loss mind-set and activity level. You will work one on one with a consultant, either in person or over the phone if participating in the Jenny Craig at home program. You will meet with your consultant every week to help keep you motivated and to provide you with support and successful strategies. Jenny Craig meals and snacks help get you started eating right. Halfway through the program, you will learn how to prepare your own healthy meals. This transition from Jenny Craig prepared food to food that you make at home is slow, to help ensure that you maintain your weight loss and are able to make a lasting lifestyle change.

Atkins

• The theory behind the Atkins diet is that if you limit your carbohydrate intake, your body will be forced to burn fat for energy. Carbohydrates are converted to blood glucose once ingested. A rise in blood glucose triggers your body to release insulin, which regulates your blood sugar levels. The glucose is released into your cells and used for energy. If your blood sugar is regulated, and insulin release is not triggered, then your body will turn to stored fat for energy. Atkins promotes a diet primarily made up of protein, fat and fiber which will maintain your blood sugar levels and boost your energy.
