Discover All About The Atkins Diet – Also Know As The Low Carb Diet

Sunday, August 23rd, 2009

Nearly everyone has heard of the Atkins Diet by now, even if not necessarily clear on what it is. Some may even know it as the source of “low-carb” diet craze in the country, but don’t know much about it beyond that. Considered as controversial as it is revolutionary, the Atkins Diet has worked successfully for a tremendous number of people, and not so successfully for a good amount of others. This article aims to place a neutral and objective eye on this popular weight loss program.

Re-introduced in the 1990’s (after an initial period of popularity in the 1970’s), the Atkins Diet is the brainchild of Dr. Robert Atkins.

The diet works in several phases, the first – or the “induction period” – lasting only 2 weeks. In this phase, dieters are not to eat any more than 20 grams of carbohydrates of any form each day. The bulk of a person’s diet during this period, then, is fats and proteins. Usually, a dieter will reach their 20 gram limit on carbohydrates simply from the small amounts in foods like salad dressing, cheese, sauces, condiments, and vegetables.

Forbidden from a participant’s diet during this 2 week induction period are fruits, grains, breads, cereal, milk, and vegetables with a high-glycemic index (a measure of the effect a food has on the body’s blood sugar).

During this period, the body enters a state called “ketosis”, where it begins burning its own residual deposits of fat in order to produce the energy for which it previously had been relying on your regular consumption of carbohydrates.

Atkins also asserts that the source of most weight problems people experience is an “insulin-resistance” that causes overweight bodies to have difficulty converting carbohydrates into glucose (or sugar) which becomes energy. In this state of ketosis induced by the induction phase of the Atkins Diet, the insulin function of the body is affected in such a way that impedes the production of more fat.

After the two week induction period ends, dieters are then permitted to increase their carbohydrate allowance by 5 grams each week. In other words: they’re allowed 25 grams of carbs per day throughout week 3, 30 grams of carbs per day throughout week 4, 35 g in week 5, etc.

Depending on the person’s body type and weight objectives, this gradual increase in carbs should level off somewhere between 40 g and 90 g per day. At this point, the dieter is considered to have entered the “maintenance” phase of the diet, where they ought to remain for the rest of their lives. Although counting calories is not a part of the Atkins Diet, studies by the North American Association for the Study of Obesity found that adhering to the restrictions imposed by the Atkins Diet led to a decrease of 1,000 calories from participant’s daily caloric intake.

A quick perusal of the recommendations published by most traditional health experts and health organizations will reveal that 40-90 grams of carbs per day is still a miniscule amount compared to that of what they consider a “standard” healthy diet.

The Atkins Diet also contradicts authorities (US FDA and the American Cancer Society included) that extol the virtues of eating fruits, vegetables, and whole grain breads and cereals. According to Atkins, even “healthy” carbohydrates are harmful in large quantities.

Studies by the Annals of Internal Medicine and the New England Journal of Medicine have actually found that participants on the Atkins Diet experienced an improvement in heart disease indicators.

Like the 80’s and 90’s were to “low-fat” and “fat-free”, Dr. Atkins has helped make the early 21st century “low-carb”. Whether that’s for better or worse is up to you.

Is Low Carbohydrate Diets Safe For Everyone?

Sunday, August 2nd, 2009

Unless you are a hermit and living without the news, you must have heard of low carb diets like Atkins diet or South Beach dieting plans. The underlying principle is that it is the excess carbohydrates and not the fats that cause weight gain.

Low carbohydrate diets advocates that we restrict the carbohydrate intake to as little as 20 grams a day or less if better depending on the program. However the Food and Nutrition Board of the Institute of Medicine of the academies of Science recommended that the daily allowance of carbohydrates for young adults should not fall below the minimum of 100 grams.

As early as 2004, both the Atkins Nutritionals and Dr. Barry Sears, creator of “The Zone”, stated that they do not recommended their products for these people and only market their dieting programs to older adults only. Dr. Arthur Agatston, the author of the South Beach Diet does recommend his plan for young adults, but they have to omit the first phase of his two weeks introductory program.

Drs. Michael and Mary Dan Eades, creator of Protein Power, says that their programs can be used on these young people so long as they start in phase two. SugarBusters, which is less restrictive in terms of carbohydrate allowances, has a separate plan for these young people.

The carbohydrates that you consume in food are the main source for cellular energy and central nervous systems functioning. Carbohydrates convert to glucose and the pranceas pumps out insulin that unlocks cells and allows the glucose energy inside. Low carb advocates says that consuming too much carbohydrate overload this finely balanced system and triggers the release of too much insulin which eventually will be stored as fats. Too much circulating insulin is also associated with insulin resistance and raises heart diseases risk.

Many low carbohydrate diets replace sugar and starches with protein rich food such as red meat and eggs. Critics of carbohydrate reduction say that the high levels of artery clogging fats and cholesterols from such foods are a one way ticket to heart diseases.

However some studies have found that after six to twelve months, many people on a reduced carbohydrate diet have actually improved their blood cholesterol level. But there are no studies longer than a year that measure the impact of these low carbohydrate and high protein diets on the cardiovascular system. Until now, we still do not have enough evidence and the jury is still out.
