In the end this diet plan didn't help me lose any weight. But it was tasty, if a little overpriced for 2 boxes or two weeks of bread and 14 days of omega 3 pills and Polyphenols.
The Debate on the Zone Diet
The Zone Diet has neither been rejected nor endorsed by health organisations. Some health experts see some elements of the Zone Diet as favourable, especially the low-fat content. The ADA (American Dietetic Association) sees the Zone Diet as just another fad diet. Some health experts argue that there are safer diets such as the ‘5 A Day’ program (which encourage people to consume five servings of fruits and vegetables a day).

| The Basic Calories are distributed as 40% carbohydrate, 30% fat, and 30% protein at every meal and snack. In contrast, most "healthy diets" recommend calories be distributed as 55-60% carbohydrate, 12-20% protein and 20-30% fat. How A Person Can Lose Weight On This Diet Calories eaten must be below calories needed to maintain weight (i.e., low calorie). This is a low calorie diet. The higher protein level of the Zone Diet can also provide more satiety with meals and snacks. High carbohydrate food portions and sweets are restricted, so blood sugar surges after a high carbohydrate meal or sweet do not occur. This also helps control appetite. Meal Plans Protein needs are based on your lean muscle mass and physical activity level. Then you divide your protein into blocks, each block of protein equals 7 grams of protein. Once you know the required number of protein blocks you give yourself one carbohydrate and fat block for each protein block. Each meal has the same number of blocks for carbohydrate, protein, and fat. For example, lunch may include 3 blocks of protein, carbohydrates, and fat. You must keep this ratio for all meals and snacks. One block of carbohydrates is equal to 7 grams of carbohydrates while one block of fat is 1-½ grams. Special Concerns People who engage in endurance exercise are at risk for poor energy levels and muscular fatigue due to an inadequate carbohydrate intake. Alcohol The Zone recommends that alcohol may be good for you if taken in moderation (~1 drink per day) preferably red wine. Claims

What You Can Eat on The Zone Diet
The Zone diet does not recommend that you eat fewer calories than you're currently consuming, just different ones. Although the book has a more complicated and exacting measurement of what to eat, it can be simplified as:
- A small amount of protein at every meal (approximately the size of your palm or one small chicken breast) and at every snack (one in the late afternoon, one in the late evening)
- "Favorable" carbohydrates twice the size of the protein portion -- these include most vegetables and lentils, beans, whole grains, and most fruits
- A smaller amount of carbohydrates if you have chosen "unfavorable" ones -- these include brown rice, pasta, papaya, mango, banana, dry breakfast cereal, bread, bagel, tortilla, carrots, and all fruit juices.
Dairy products are not verboten, but The Zone diet devotes little time to them, except to explain how quickly they release glucose. Sears prefers egg whites and egg substitutes to whole eggs, and low-fat or no-fat cheeses and milk.
The Zone diet keeps saturated fats to a minimum but includes olive, canola, macadamia nuts, and avocados. Certain unfavorable carbohydrates are restricted because they release glucose quickly: grains, breads, pasta, rice, and other similar starches, a deviation from conventional definitions of a good diet. Overall, the diet is higher in protein and fat than traditional diets, which would have us eat nearly three-quarters of all calories as carbohydrates.
Happily for those of us who would be depressed at the thought of forgoing desserts for the rest of our lives, his list of allowable foods includes, among others, high-fat ice cream. Why high-fat? Because the fat retards the rate of absorption of carbohydrate into the body, according to Sears. Alas, the recommended portion is a mere half-cup.
Food For Thought
The 40-30-30 ratio of The Zone diet applies to all meals all the time, and a broad range of foods are allowed, so there are no confusing schedules or conditions that need to be memorized. Though dieters should find it easy to follow, nutritionists give The Zone diet mixed reviews.
Pros: great idea for healthy bodies. Cons: Nothing everyone shouldn't already know. The Zone Diet is pretty muck just a book that will tell you what you should already know. Eat right and exercise. |
