Average Reviews:
(More customer reviews)Like many of you, I found myself wondering what the differences were between the various diet programs. What I discovered is that all of the major diet books are well written and share many similarities. None of them offered an "silver bullet" to weight loss - it primarily comes down to keeping your calories burned greater than your calories eaten. There are theories presented about glycemic index, good vs. bad carbs, etc., but at the end of the day it's about calories and exercise.
In this review, I've summarized Consumer Reports evaluations to offer brief summaries of each diet book/program in hopes that it might help you pick out the one that would work best for you. Don't pay too much attention to the number of stars, as it's my own subjective rating based on effectiveness, ease of use, and ability to stick with the diet. Instead, try to discern which diet might fit your lifestyle better.
The Abs Diet, ****
This book is written by David Zinczenko, the editor of Men's Health Magazine. The diet likes the number 6 - promising "6 pack abs in 6 weeks," by eating 6 meals a day. Each meal is built around the "power 12" foods. There is a strong emphasis on whey supplements. The fitness program was easy to follow but perhaps too strenuous for beginners and seemed better suited to men. Strong points are excellent nutritional content and strong exercise. Weak points are questionable claims about rapid weight loss and "6 pack" abs, and mediocre meal plans. Average recommended daily calories are 1,890, with 7 fruits and vegetable servings.
The South Beach Diet ****
The SB Diet is a slightly more permissive version of the Atkins low-carb diet. It is based on the premise that eating low-glycemic foods (foods that raise blood sugar) decreases cravings for sugar and refined carbs. Like many of the diets, there are two phases. In the first phase, fruits, sugar, and grains are banned outright. Phase 2 allows some fruit, high-fiber grains, and dark chocolate. The simplicity of the diet might appeal to many busy dieters. However the emphasis on the glycemic index and insufficient exercise sections are a drawback. Recipes are easy to prepare, but some called for unusual ingredients (a clever cook could make substitutions). Average recommended daily calories are a mere 1,340, with 13 fruits and vegetable servings (mostly veggies).
The Sonoma Diet ****
The Sonoma Diet is an updated low-carb diet with a Mediterranean theme. Again, it is broken into two phases, called "waves." In "Wave 1," the dieter is banned from eating most sweet or refined foods. The much longer "Wave 2" permits fruits and wine. It has a unique method of calculating portions by filling sectors of small plates with specified food categories. The diet is healthy but complex. It is also very restrictive, which makes it more difficult to stay on. Also, the book doesn't offer enough on exercise. The recipes were tasty but elaborate to prepare. Average recommended daily calories are a mere 1,390, with 10 fruits and vegetable servings.
Ultra-Metabolism ***
The Ultra-Metabolism Diet is designed around the assertion that people get fat because their body's systems become toxic, inflamed, and imbalanced. Again, this is a two phase diet. Phase 1 is an initial "detox" period. The longer Phase 2 is a "rebalancing" period. Overall, the dieter must eliminate white rice, refined grains, most red meats, and caffeinated beverages. The theory of your body requiring detoxification goes beyond any scientific evidence and rings a bit of late night television "miracle detox bowel-cleansing pills." The diet is fairly restrictive and complicated. The exercise section was brief but practical. Average recommended daily calories are 1,660, with 12 fruits and vegetable servings.
Volumetrics, ****
The Volumetrics Diet is based on Penn State research. It aims to maximize the amount of food you can eat for a given caloric intake. This is done primarily by eating reduced-fat products, adding in lots of vegetables, and using low-fat cooking techniques. It encourages eating a first course of broth-based soup or low-calorie salad (not heavily laden with dressing, cheese or bacon) to take the edge off your appetite. Recent clinical studies have shown this diet to be very effective. The recipes are appetizing but time consuming. Average recommended daily calories are 1,500, with 14 fruits and vegetable servings.
The Zone Diet, ****
The Zone Diet was designed to keep your blood sugar and hormones at optimal levels so that you can better fight obesity and diseases. It requires that each meal consist of 30% protein, 30% fat, and 40% carbs (based on calories). The diet allows many fruits, but almost no grains except oatmeal. The meals are simple to prepare and nutritionally balanced. But having to keep to the 30/30/40 balance is very tedious and requires lots of preplanning. Recent studies showed that the overall weight loss was below average. Average recommended daily calories are 1,660, with 17 fruits and vegetable servings.
Eat More, Weigh Less, ***
The Eat More, Weigh Less (Ornish) Diet is a low-fat vegetarian diet that bans all meat, fish, oils, alcohol, sugar, and white flour. Their clinical studies suggest that strictly following the diet can prevent or reverse some diseases. Ornish argues that it is easier to make drastic changes to diet rather than small ones. The diet offers the most food per calorie of any of the diets. It is actually lower in fat than current USDA guidelines recommend. Studies have shown good long term weight loss, but a relatively high drop-out rate. Average recommended daily calories are 1,520, with 17 fruits and vegetable servings.
Dr. Atkins New Diet Revolution, ***
The Atkins Diet is the grand daddy of them all. As with many of the other diets, it is divided into two phases. The first phase is a two week induction period that bans nearly all carbs. The second phase is only slightly less restrictive, but does slowly add more vegetables, fruit, and wine. Research has suggested that Atkins' dieters are less hungry than on many other diets. But the diet is difficult to adhere to and has a high drop-out rate. Long term weight loss has been shown to be average. The single most glaring concern with the Atkins diet is that the nutritional profile is far outside conventional dietary guidelines. (We've all known people eating handfuls of bacon, eggs, and cheese for breakfast, claiming they were on a diet). Average recommended daily calories are 1,520, with 6 fruits and vegetable servings.
Again, please don't worry too much about my ranking of the diet books - it's completely subjective. My suggestion is to simply find a program that seems to fit your lifestyle best.
Please be kind enough to indicate if reviews are helpful.
