The Atkins diet is utter bollocks.

Pound for pound, fat contains twice the calories of proteins or carbohydrates. FACT

The body converts energy it cannot use immediately as body fat. FACT

Therefore, consume more calories than the body uses and your body fat volume will increase. FACT

If you want to make your body use more energy, turn your heating system down. About 90% of the energy a mammal consumes is used to maintain a stable body temperature. That's the main reason why we're more obese as a nation now than fifty years ago - fifty years ago many people didn't have central heating or double glazing. Turn your heating down and make your body work harder to maintain that temperature. Use energy without effort!

Atkins is not only substantiated as extremely unhealthy but it gives false positives. The reason that you lose a lot of weight initially is becaus your body loses it`s ability for water retention and what you lose is all your excess water.
It`s dangerous and people should not be allowed public sector healthcare if they continue to abuse their bodies in this manner. There is no substitute for a balanced diet and a bit of hard work. Atkins is for lazy people who want a quick fix, but after the first two weeks when the water has gone then the weight stabilizes and the body then starts to digest muscle due to having no carbohydrate to feed on.
I love these people who say 'read the book, it`s amazing' well duh! It`s bound to be as it`s a commercial venture. Read the bible, that`s also amazing, but it`s full of unsubstantiated bollocks.
