Fad Diets by: Kirsten Hawkins

High-Fat, Low-Carbohydrate Diets - Millions of Americans have joined the low-carb craze and started high-fat, low-carb diets such as the Atkins Diet, and the Zone Diet. They are made up of about 60% fat, 10% carbohydrate, and 30% protein. These diets say you can eat high amounts of fat and protein while getting very low amounts of carbohydrates in the form of vegetables. The main premise of the low-carb diet is that a diet low in carbohydrates leads to a reduction in bodyÕs production of insulin. The end result is that fat and protein stores will be used for energy. So you stuff yourself full of unlimited amounts of meat, cheese, and butter, and only eat a small portion of carbohydrates.

People who start the diet usually lose a great amount of weight, but itÕs not permanent weight loss. Instead of burning fat, the lose water and precious muscle tissue. Furthermore, these diets are low in several nutrients and contain excess amounts of cholesterol and saturated fats, substances that increase the risk of heart disease. Plus, regardless of what they claim, the enormous amounts of protein put a strain on your kidneys.

Moderate Fat Diets - Next, there are the moderate fat diets. Moderate fat diets include diets like Weight Watchers, the USDA Food Guide Pyramid, and Jenny Craig. These diets are made up of about 25% fat, 60% carbohydrate, and 15% protein. They encourage the intake of whole grains, fruits, vegetables, and essential fatty acids found in foods like olive oil and salmon. These diets are usually nutritionally balanced if the dieter eats a variety of foods from all categories. For example, Weight Watchers operates on a point system where foods get a number of points based on calorie, fiber, and fat content. Dieters get a specific amount of points they can use for the day. While itÕs not encouraged, they may choose to spend most of their points on carbohydrates instead of balancing it out. This could lead to deficiencies in nutrients such as calcium, iron, and zinc. However, if followed properly, these diets are probably the most successful for losing weight and keeping it off.

Low and Very Low-Fat Diets - Finally, you have your low-fat and very low-fat diets. Diets in this category include the Dr. Dean OrnishÕs Diet and the Pritkin Plan, among others. They are made up of about 13% fat, 70% carbohydrates, and 16% protein. These diets are mostly vegetarian diets and donÕt recommend eating a lot of meat. Like the low-carb diets, you can eat unlimited amounts of certain foods. Because you canÕt eat a lot of meat, these diets are deficient in zinc, vitamin B12, and essential fatty acids. Also, it is so restrictive that people find a hard time staying on it for life and end up gaining their weight back.

The South Beach Diet by: Charlene J. Nuble

Among the most popular forms of dieting is the South Beach diet, developed by cardiologist Arthur Agatston of Miami, Florida.

The South Beach diet is always confused with Atkins Diet, which is a low-carbohydrate diet. The South Beach diet highlights the consumption of “good carbohydrates” (high in fiber) and low in glycemic index. The South Beach diet was developed for patients with heart problems to lose weight without risking ketosis. The weight loss was a side effect which turned out to be beneficial and this encouraged many people to try South Beach diet.

According to the South Beach diet theory, highly processed carbohydrates are quickly digested which makes insulin level to shoot up. Once the carbohydrates are all used up, your high insulin level makes you crave more for carb-filled foods.

The South Beach diet is based on the observation that Americans are carb crazy, which is also the reason for the induction phase. In the first two weeks, dieters attempt to eliminate bad carb such as grains or fruits. After this phase, grain-based foods and fruits are returned to the diet with the concentration on foods with low glycemic index.

The South Beach diet also emphasizes the difference between good and bad carbohydrates, and good and bad fats. Good carbohydrates have low glycemic index which means that they are slowly digested and absorbed. The South Beach diet bans unhealthy fats such as saturated fat.

Finally, the South Beach diet stresses a permanent change in one’s way of eating. The South Beach diet suggests whole grains along with large amounts of vegetables, with sufficient amounts of monounsaturated and polyunsaturated fats, plus Omega-3 oils. The South Beach diet discourages eating of overly refined foods such as flour and sugar.

According to experts, the South Beach diet met the criteria of healthy diet which is a good thing. The bad thing is the induction phase wherein dieters lose weight due to loss of water. Losing a large amount of water can disturb one’s electrolyte so if you’re following the South Beach diet, it would be better if you work closely with a doctor.

According to Dr. Agatston, South Beach diet is neither a low carb nor low fat diet but the restrictions placed in the induction phase cut big time the carbohydrate and fat intake of dieters. The good thing about the South Beach diet is that it teaches people on the right foods to eat to cut the risk of heart problems and high cholesterol as well as help them lose weight. The South Beach diet is a long, tedious journey towards perhaps a drop dead gorgeous body. But more than phases of losing weight, the South Beach diet is a way of life.
