The Zone Diet

Zone diet program scrn

Written by US biochemist Barry Sears, the Zone Diet is one of the most well known low carb high protein diets. To enter The Zone 40 percent of your daily calories must come from carbohydrates, 30 percent from fat and 30 percent from protein. According to Sears, such a diet produces optimum fat-burning and weight loss.

Some Expert Views on Atkins Diet

Dr. Foster, one of the researchers involved in studying the Atkins Diet, acknowledged the possible health dangers of the Atkins diet and stated a longer five-year study was planned.

This larger study of 360 participants will help us more fully assess the benefits and risks of low-carbohydrate diets on bone mass, kidney function, arterial function and exercise tolerance, he said.

Im very, very concerned that people will get the message from these studies that the Atkins diet is safe and effective, but I dont believe we know that yet.

Brigid McKevith, a nutrition scientist at the British Nutrition Foundation (BNF), said.

We welcome the fact that the Atkins diet is being studied scientifically and that randomised controlled studies have been carried out, because its very popular with the public. however There are several potential problems with the Atkins diet. These include long term bone health, as with a very high protein intake the excretions of calcium increase, so there could be implications for the health of bones, she explained.

There could be difficulties for people who have an underlying problem with their kidneys or liver, because it would be putting more strain on those organs, and problems in terms of heart disease too, as its a diet very low in fruits and vegetables. Also, its very low in fiber, so in terms of digestive health, its not in keeping with our fibre and complex carbohydrate recommendations.

Belinda Linden, head of medical information at the British Heart Foundation, holds similar views.

The new studies do not indicate a dramatic weight loss for excessively obese people, she said. Previous studies have shown that weight loss from the Atkins Diet may involve muscle loss rather than body fat. Another potential problem is that it is so far unclear from studies whether weight loss is sustained over a longer period than six months. One of the studies shows no significant difference at 12 months.

She added that.

With minimal fruit and vegetables included in the diet, it holds serious implications for coronary heart disease and cancer. Diets need to be varied to protect against these conditions - and this one isnt. This diet requires further long term and larger studies before its effectiveness can be confirmed.

Susan Barr, registered dietitian in New York City, says.

There have been reports in the medical literature that say that this low-carb diet may not be as bad as we thought. That makes people interested again in this diet, but until there is more research on what stresses the diet places on the body, there is no way to know what it might be doing besides providing short-term weight loss.

Volumetrics author Barbara Rolls, PhD, who holds the Guthrie Chair in Nutrition at Penn State University, offers a very simple explanation as to why people lose weight on Atkins diet.

Theyre cutting calories, even if they dont realize it. No one has shown, in any studies, that anything magical is going on with Atkins other than calorie restriction. The diet is very prescriptive, very restrictive, and limits half of the foods we normally eat. In the end its not fat, its not protein, its not carbs - its calories. You can lose weight on anything that helps you to eat less, but that doesnt mean its good for you.

Neal Barnard, MD, president of the Physicians Commission for Responsible Medicine, a non-profit research group based in Washington, says.

Low-carb diets have been linked to increased frequency of colon cancer, formation of kidney stones, kidney disease, and even osteoporosis... The reason for the health worries is in large part due to red meat. People who eat meat every day have three times greater risk of developing colon cancer. And then there is the problem of the kidneys. They arent designed to work on an oil slick of fat.

The Atkins Diet Controversy Continues

Atkins Diet supporters claim it offers faster weight loss and a relatively user-friendly eating plan. Sceptics, including dietitians and nutritionists, maintain that Atkins Diet weight loss is both short-term and possibly a health risk, even though the weight loss itself may have the beneficial effect of lowering cholesterol.

South Beach Diet

The South Beach Diet is a doctor-designed low-carb weight loss plan. Even though the initial stage of this diet is high protein, low-carb, it is less stringent than other well known high protein diets, like Dr Atkins Diet.

Phases of South Beach

The diet is split into 3 phases. The first phase is most restricted and involves eating three normal-sized meals made up of a limited number of foods - lean meats, vegetables, nuts, cheese, and eggs. Beef, ham, milk, yogurt, all carbs with the exception of some vegetables and alcohol are excluded.

Phase 2 introduces some of these banned foods back into the diet, while Phase 3 is designed to include foods from all the food groups and lasts for life.

Possible Weight Loss on South Beach Diet

The projected weight loss during the initial phase of the diet (which lasts 14 days) is 8-13 pounds, but like all low-carb, high protein diets, a good proportion of this is water loss rather than fat loss.

Phase 2, which lasts until you get to your goal weight, promises a weight loss of 1-2 pounds per week. This is the average weight loss recommended by health experts, so weight loss on the South Beach Diet is no faster or slower than most weight loss plans on the market.

The final phase of the diet gives sound advice on long term healthy, balanced eating and if followed, like any healthy eating plan will help maintain good health and weight for life.

A Low-Carbohydrate as Compared with a Low-Fat Diet in Severe Obesity

ABSTRACT

Background

The effects of a carbohydrate-restricted diet on weight loss and risk factors for atherosclerosis have been incompletely assessed.

Methods

We randomly assigned 132 severely obese subjects (including 77 blacks and 23 women) with a mean body-mass index of 43 and a high prevalence of diabetes (39 percent) or the metabolic syndrome (43 percent) to a carbohydrate-restricted (low-carbohydrate) diet or a calorie- and fat-restricted (low-fat) diet.

Results

Seventy-nine subjects completed the six-month study. An analysis including all subjects, with the last observation carried forward for those who dropped out, showed that subjects on the low-carbohydrate diet lost more weight than those on the low-fat diet (mean SD, 5.88.6 kg vs. 1.94.2 kg. P=0.002) and had greater decreases in triglyceride levels (mean, 2043 percent vs. 431 percent. P=0.001), irrespective of the use or nonuse of hypoglycemic or lipid-lowering medications. Insulin sensitivity, measured only in subjects without diabetes, also improved more among subjects on the low-carbohydrate diet (69 percent vs. 38 percent, P=0.01). The amount of weight lost (P

Conclusions

Severely obese subjects with a high prevalence of diabetes or the metabolic syndrome lost more weight during six months on a carbohydrate-restricted diet than on a calorie- and fat-restricted diet, with a relative improvement in insulin sensitivity and triglyceride levels, even after adjustment for the amount of weight lost. This finding should be interpreted with caution, given the small magnitude of overall and between-group differences in weight loss in these markedly obese subjects and the short duration of the study. Future studies evaluating long-term cardiovascular outcomes are needed before a carbohydrate-restricted diet can be endorsed.

Zone Diet Eating Plan

Sears advises you to follow the Zone diet calculation exactly, which can be a little complicated, although since the Zone diet program came out, some people have simplified the Zone calculation. You should eat a small amount of protein at every meal and at every snack (one in the late afternoon, one in the late evening). Favorable carbohydrates include most vegetables and lentils, beans, whole grains, and most fruits. Eat a smaller amount of carbs if you have chosen unfavorable carbs like brown rice, pasta, papaya, mango, banana, dry breakfast cereal, bread, bagel, tortilla, carrots, and all fruit juices.

How The Zone Diet Helps You Lose Weight

For most dieters, entering the Zone necessitates a significant reduction in calories and it is this calorie reduction which is the cause of any weight loss, not the 40.30.30 nutrient split.
