No food is completely banned, but if you’re a carb-lover, you may find getting used to the Zone plan challenging. It encourages you to think of bread, pasta, grains, and other starches as condiments rather than as main or even side dishes.
Veggies and fruits that are relatively high in sugar -- like corn, carrots, bananas, and raisins -- are on the “unfavorable” list. Fatty red meat and egg yolks fall into the Zone’s “bad fats” column.
The Zone Diet sets a realistic and healthy weight loss goal of 1 to 1.5 pounds a week. Most health experts also recommend this proven strategy for a sure and steady weight loss. The National Institutes of Health (NIH) in their guidelines recommend that a good weight loss program should aim for a loss of 1 to 2 pounds each week.
Many people experience quick weight loss when starting the Zone diet. This is often seen as affirmation. What they don't realize is that diets like this one that are low in carbohydrates result in a large amount of fluid loss. Carbohydrates hold fluids and when we reduce the amount we consume, we also reduce our capacity for those fluids. Don't mistake this initial loss of water weight as true weight loss.
There is no scientific evidence to back up the truth of the zone diet, but there are technically no known side effects.
This diet is good for people who just need to lose a little bit of weight. Maybe for a better beach body or to fit into some old clothes. I would not recommend this diet if you are trying to lose a lot of weight and look a lot better. There are better diets that go along with workouts that may be more beneficial.
