Truth About Diets

Twin brothers Bill and Jim Germanakos are the creators of and the Rapid Action Metabolism Fat Loss System.

Bill was one of the contestants on the television program ‘The Biggest Loser’ where he lost 164 pounds and was the winner of that season. Jim simultaneously competed in a local competition where he lost 186 pounds and was also declared the winner.

In the Rapid Action Metabolism Fat Loss System they share the insights they have learned on their journey and promise dieters that total body transformation becomes easy when you have the right knowledge.

Truth About Diets Basics

Bill and Jim say that the most important thing you need to lose weight is education about proper diet and exercise. They state that one of the main things they learned was how to achieve a faster metabolism and this is the foundation of their system.

The basic structure of the Truth about diets involves eating 40% protein, 40% carbohydrate and 20% fat. In addition dieters are instructed to follow some basic rules that will help to increase metabolism. These include never skipping breakfast, always eating protein at breakfast, eating frequent small meals, getting enough sleep and drinking lots of water.

They also highlight that it is important to make a lifestyle change rather than adopting a diet as a short-term approach to weight loss. Otherwise when you return to your old habits you will regain the weight you have lost.

A great deal of emphasis is placed on emotional factors that may influence weight gain. They say that the most important thing that happened to them on ‘The Biggest Loser’ was discovering the emotional reasons why they were overeating.

The program also includes a 4-Week Diet and Exercise Blueprint, which includes a specific strategy that will enable you to lose up to 20 pounds in one month.
