I do not disagree with the metabolic advantage theory put forth by ketosis diets at all!
You can't use basic thermodynamics when it comes to our bodies because different macronutrients do different things within the
body, so while a CALORIE is just a CALORIE, how that macronutrient is metabolized can be very different.
The real reason ketosis diets are more effective at weight-loss in the short term is due to the HIGH protein content of those diets. Protein turn around is beneficial for weight-loss, which is why you find Steve recommending to a lot of people getting in 1 gram per
pound (TBW or LM); basically if you have more protein floating in your blood stream at all times, it won't go for the muscle stored in your
body, so it then turns to the
fat stores first. Also, ketosis diets are usually in a caloric deficeit as well, the trade off being refined carbs (snacks, pizzas) being eliminated and being replaced with vegetables (low in carbohydrates). Still, the negative effects of those plans (hypertension, and cholesterol and triglycerides levels to name a few) are much risker than the weight-loss benefits (which could have been achieved via LCDs).
Further more, it's rare for you to find someone who has sustained a weight-loss of 30
pounds or more for six years within the National Weight-loss Registry that was on a ketosis
diet. There just isn't a sensible way to maintain and stay healthy on those plans.
So someone who is on
Atkins, vs a LCD, will actually lose weight quicker... in the same amount of time (for the same amount of
calories). But then go look at those two people a year later and see where they are at...
