In an attempt to prevent his death from a heart ailment as some family members had, Dr. Barry Sears utilized his biochemistry knowledge to create the Zone diet. The Zone diet is made up of a carb, protein and fat ratio that is to be strictly observed each day. By eating a consistent diet of 30 percent fats, 40 percent carbs and 30 percent protein, the ideal Zone nutritional ratio is consumed. Keeping the ratio intact during the Zone diet is important for keeping the hormone levels and blood sugar steady throughout the day. Weight loss also occurs as a result of this diet.

Doctors know now that eating a very low level of fat is not an effective weight loss plan. With low fat comes more insulin, which leads to more fat rather than less. This causes the failure of many diets that strictly limit fat. Another reason for its failure is that a diet low in fat is unsatisfying, leading to a larger appetite and more calories being eaten. Monounsaturated fats are an important part of staying on the Zone diet. Burning the fat that results in weight loss is helped buy taking in these fats. Without it, insulin levels may be too high to burn off the extra fat for energy.

A few simple measurements are provided to decide how much of each nutritional item is enough. Protein the size of the palm is one serving. When you’ve eaten enough healthy fats, you will no longer be hungry. Carbohydrates should be eaten in an amount that will keep the mind working clearly. Eating more than those amounts each day are oversized portions that will not aid in weight loss. Any amount of starchy vegetables can be added to the diet, without restraint.

Besides eating the correct ratios, the diet also requires eating omega fatty acids. The right combination of omega-3 and omega-6 acids is important for a healthy heart as well as a healthy mind. The diet requires some supplements of fish oil or other omega acids. Dr Sears originated the capsules, which he developed to be a healthy ratio of both omega fatty acids.

The Zone has been studied many times, and it has been found to be a sound diet that results in weight loss. The period of adjustment for new Zone dieters is shorter than the adjustment experienced with different diets. The side effects are few, including temporary fatigue, and last no more than the first few days of the diet. Once the correct food ratio has been reached, and is maintained long term, the body becomes more efficient in many ways. Keeping the insulin levels steady also keeps energy and moods steady. This furthermore improves mental agility. Staying with the diet keeps the body in the perfect insulin zone, which is where the diet’s name came from.

The Atkins Diet started in the 60s when Dr. Robert Atkins uncovered an alternative way to deal with his own problem with being overweight. Finding it successful, he promptly began treating his patients with the same diet. In 1972 he released Dr. Atkins’ Diet Revolution, which rapidly became popular diet. He later updated the book with new guidelines in 1998. This sparked new interest in the Atkins diet, and an whole new industry began, dealing in packaged foods that fit the diet.

The essential principle of the Atkins Diet is to take in a diet which is low carb and high protein. To get to the point of utmost weight loss, there are four phases that the Atkins Diet embodies. The four parts of the Atrkins Diet were classified to commence body’s weight loss and also to sustain the ideal weight for the rest of the dieter’s life.

The beginning step of the Atkins Diet, induction, is the diet’s most difficult phase for many dieters. Induction has the dieter eating a very low quantity of carbohydrates- 20 grams or less per day. At least 12 of the carbohydrate grams have to come from vegetables. The amount of fat that the dieter eats is not factored into the diet- only the amount of carbs. A multivitamin supplement is to be taken to ensure that no vitamins or minerals are left out of the diet.

The second phase, called ongoing weight loss, allows the dieter to eat more carbohydrates. Every week the quantity of grams increases by two, as long as the dieter is still losing weight. Dieters stay within the ongoing weight loss phase until they get close to their original weight goal. To make certain that the dieter is still losing weight, many people on the Atkins Diet make use of ketosis sticks. These small pieces of paper are placed into the urine and quickly change colors to tell the dieter whether weight is being lost.

The third step, pre-maintenance, allows the Atkins dieter another raise in carbohydrate grams. Dieters eat an extra 10 grams of carbohydrates every week, unless weight gain results. The main idea of pre-maintenance is to identify the maximum number of carbohydrate grams that can be eaten without gaining any weight. Once this level has been reached, the dieter is set to begin the final step to stay at that weight forever.

Lifetime maintenance is the step in which the dieter decides to keep the carb number at a level that keeps the dieter from gaining weight. The Atkins Diet recommends eating natral, foods that have not been processed as often as possible during the lifetime maintenance phase. If the dieter starts to gain weight, the other phases should be gone through again until the weight is brought back down.

The grams of carbs that are kept track of during each step of the diet are the “net carbs”. This number of carbs is the number of carbohydrates that have been eaten, with the total number of glycerin, fiber and sugar alcohol grams removed from the equation. Those substances limit the effect of carbs on the body, and each gram cancels out one carb gram. Most of the products made specifically for the Atkins Diet, which are sold by Atkins Nutritionals, are items with higher carb counts, but that are made with sugar alcohol and fiber to drive the amount of carbs to be counted lower.
