what about him?
he's the so called pioneed of low carb diets (although low carb diets are what primative man were on anyway)
Atkins states that if once watches carb intake they can get into the "Metabolic Advantage" which means they no longer need to worry about calories, only carbohydrate grams and still lose weight by "Pissing fat cells out in ketones"
This is a load of hogwash. Whilst a low carb lifestyle has it's benefits and certainly leads to weight loss, the metabolic advantage goes against the laws of thermodynamics and does not exist.
However, eating a diet rich in protein and fats leads to more satiety than a diet high in carbohydrates which means you will probably eat less calories over all on a low carb diet meaning you lose weight. Low carb diets also mean less insulin spikes since carbohydrates are responsible for insulin spikes and it's insulin which is highly anabolic to fat especially thngs like refined carbs, and fructose, found in fruit which fills liver glycogen and liver glycogen easy converts to fat in adipose tissue, a process known as lipogenesis denovo.
Whilst fat is the body's preferred source of energy since it is so concentrated, it can take many months to fully fat adapt so that one uses fat efficiently as energy. If you're looking for fat loss then controling carbs is important but ultimately it's calories that are important. Carbohydrates should be consumed after working out though, preferably in the form of Liquid high Glycemic carbs such as glucos, mixed with protein this will shuttle nutrients to the body and thus aid the recovery process
