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.

Low Carb Diet – Weight Loss Benefits

Sunday, August 9th, 2009

A low carb diet, as the name implies, is a diet that is low in carbohydrates (bread, rice, sugar, especially the refined variety) and high (or rather adequate) in fats and proteins (meat, eggs, cheese, butter, nuts, etc.). A number of variations of the diet exist (most well known, Dr. Atkins Diet), but the one thing that is common to all is the drastic cutback on the intake of carbohydrates in the diet plan.

Most of these plans substitute the outgoing carbohydrates with fats and proteins. Although different types of these diets may vary in the recommended intake of carbohydrates, fats and proteins, as a general rule a low carb diet is tantamount to a high-fat and moderate protein diet.

In a low carb diet at least 60 to 70% of the daily calorie intake must come from fats, contrary to a normal diet where a major portion of the calories comes from carbohydrates. The carbohydrate calories should not constitute more than 5 to 10% of the daily calorie intake. The remaining 20 to 30% calories can come from proteins.

Why a low carb diet?

How often have you come across overweight people feeling frustrated at not being able to lose an inch of the stubborn abdominal fat in spite of exercising and in spite of being on the traditionally recommended low fat, high carb diet for months? Too often to even remember! The reason, obviously, has to lie in the wrong approach to attack the problem underlying excess weight and excess inches.

Scientific research has shown that dietary fat is not necessarily converted into body fat, whereas carbohydrates readily convert into fat by the action of insulin, a hormone produced by pancreas in response to elevated sugar levels in the blood (as caused by carbohydrates) to allow blood sugar to be used by cells.

However, insulin also aids in fat deposition and stimulates the brain to produce hunger pangs. The vicious cycle of more carbohydrates, more and more insulin repeats, resulting in cells becoming insulin resistant with time. Consequently, excess sugar either stays in the blood (causing diabetes) or starts converting to fat (causing obesity) instead of being used up by cells to produce energy, leading to obesity, fatigue and lethargy.

Benefits of a low carb diet

A low carb diet helps prevent hyperinsulinemia (i.e., elevated insulin levels in the blood) and increases the level of glucagon, a pancreatic hormone that reverses the action of insulin, stabilizes blood sugar levels, and helps burn fat to energy and remove cholesterol deposits from arteries.

And because the body gets into the fat-burning mode, sustained weight and inch loss occurs, accompanied by lowered blood pressure, better lipid profile and raised energy levels.

Due to the consumption of fats and oils, the appetite and hunger pangs stay in control, because fatty foods are more satisfying and take longer to digest. And since limited amounts of complex carbohydrates do accompany the fats (obviously, the healthy types), the body metabolism does not switch to starvation mode. A vitamin/mineral supplement and a fiber supplement may be added if necessary.

Once the body chemistry is back to normal and the excess weight knocked off, complex carbohydrates and some vegetables/fruits can be added to the diet. But if one does not want to go back to the earlier state, one has to kiss goodbye the white bread, pastries, cakes, ice creams and things like that, except for an occasional binge.
