There are so many weight loss diets being promoted by different gurus everywhere. In the midst of all the noise and confusion it is often so hard to know distinguish fact from fiction. But we will attempt to do just that… Here’s a description of some of the popular weight loss diets.

The South Beach Diet

The South Beach Diet is a phased approach to weight loss and nutrition. In the three major phases dieters will eat selected foods and avoid others, in order to balance the glycemic index to lose weight and achieve optimal metabolism. Click here to read more about south beach diets.

The Zone Diet

The Zone Diet is similar to the South Beach diet in some ways. But here the emphasis is less on adjusting the Glycemic Index by adjusting the types of carbohydrates and fats consumed and more on the proper ratio of these with proteins. Click here to read more about the zone diet.

Low Fat Diets

This diet emphasizes decreased fat consumption over all other things. Click here to read more about low fat diets.

Low Carbohydrate Diets

Low carbohydrate diets help lower the one thing that all good diets aim at: reduced calories. There’s no getting around the fact that more calories consumed than used leads to weight gain. Reducing carbs the right way can ‘cut to the chase’, nutritionally speaking. Click here to learn more about low carb diets.

The Zone Diet

The basic idea of the Zone Diet is to adjust the ratio of carbohydrates: proteins: fats to 40:30:30. This means that 40% of calories consumed should be in the form of carbs, 30% from proteins and 30% as fats. Some studies suggest that 30% of proteins is far higher than is healthy for some individuals, particularly those with kidney ailments. The American Heart Association recommends about 10%.

Like the South Beach Diet, one important goal is to adjust insulin levels. But it goes beyond this in attempting to achieve a well-balanced hormone system in general.

One reason is the view that excess insulin production tends to cause the body to convert carbs to stored fat, contrary to most dieter’s goals. By contrast, proteins help stimulate the release of glucagon, which stimulates the liver to shed stored carbs. That in turn leads to a feeling of satiation and a person naturally stops eating, according to the theory.

Unlike South Beach, however, there is a strict emphasis on calorie counting. No more than 500 calories should be consumed during any meal, and no snack with more than 100 calories should be eaten between meals. Balancing carb intake with 3-4 ounces of proteins helps achieve that desired glucagon-insulin balance.

The Zone Diet emphasizes eating fresh vegetables and fruits throughout the dieting period. Nuts, leafy greens and mono-unsaturated fats are preferred. Meals are consumed on a regular schedule, with breakfast consumed within an hour of waking. Carbs from fruits and vegetables are preferred over those from starchy foods like potatoes and pasta.

Alcohol is allowed, but it’s recognized as high glycemic, high-sugar carbohydrates. So, a 4-oz glass of wine would require a trade-off for a ‘block’ of food carbs (36-40 grams). Coffee is discouraged, since it is a stimulant that causes insulin resistance. Water is the beverage of choice in the Zone Diet.

Still, no specific food or drink is expressly forbidden. The idea is to achieve a balance in order to regulate hormone levels. Like any diet, it will need to be adjusted to a particular individual’s circumstances and needs.

The net result of following the diet, according to practitioners, is the desired weight loss while maintaining healthy nutrition. Many report that any cravings disappear in a couple of days. It’s often recommended for those with diabetes by some nutritionists, since it works to adjust insulin levels.

As with any new diet, seeking the advice of your physician is wise. He or she can help you tailor the Zone Diet to your specific situation.

The Glycemic Index

The GI is a measure of the relative amount of blood sugar created in response to consuming carbohydrates. Different carbs metabolize at different rates and slowing the absorption of sugars is one way to shift insulin levels, which play a role in storing excess calories as fat, according to South Beach Diet inventor Dr. Agatston, a Florida cardiologist.

The basic equation – more calories used than consumed leads to weight loss – still holds. But this approach to dieting and weight loss attempts to shift how those calories are used.

Phase 1

In Phase 1 of the South Beach diet, which lasts exactly two weeks, the focus is on shifting from high fat carbs to low fat carbs, such as from fatty cuts of beef to boiled ham. It also attempts to reduce starches such as bread and potatoes, moving instead to foods such as pinto beans and black eyed peas. Sugary soft drinks are eliminated completely. No beer or wine is allowed during this period.

The idea is to adjust the body’s cravings away from high sugar-content, high-fat content foods. This, according to the theory, helps flip the body’s ’switch’ that causes us to store fat. When the switch is on we may crave certain foods, but after ‘retraining’ those cravings disappear gradually.

Portions remain at normal sizes however, and there’s no concentration on counting calories. That makes it simple to develop lists of allowed and forbidden foods to eat during these two weeks.

Phase 2

In Phase 2 some of the rules are relaxed a little. Certain formerly forbidden foods may be consumed. Pasta and bread, in moderate quantities, are back on the ‘Allowed’ list. Dieters can choose from a wide range of foods, such as rice, cereal, fruit and more. The allowed foods to emphasize should be those with a low-GI index. Red wine is re-introduced, again in moderation.

This period lasts as long as needed to achieve the individual dieter’s weight loss goal. For some that may be only a few weeks. For others, it may require several months or more.

Phase 3

Once the weight loss goal is achieved, it’s important to be able to keep those pounds off. Many dieters become frustrated because they see hard-to-lose pounds come sliding back on over time. Phase 3 represents a lifelong commitment to a change in eating habits that will help retain that hard-won goal.

The emphasis is on ‘good’ carbs versus ‘bad’ carbs, as well as choosing ‘good’ over ‘bad’ fats. Good, here, means low GI, bad is high-GI. High fat meats are still discouraged, except as an occasional indulgence. Refined sugars are a no-no. Fiber, to slow digestion of carbs, is considered good, as is eating foods with ample Omega-3 fatty acids, such as fish.

Summary

The South Beach Diet can be put in the category of ‘low carb’ but the emphasis is more on the type of carbohydrates than the amount contained. As with any major diet change considered, consulting your physician before starting is always wise.
