Doctor Atkins ...
Well ... where do I start?
I HATE this guy. No, I mean I really - quite literally - white-hot despise this guy. In fact I'm glad he's dead, and I don't give a damn what anyone thinks about me saying that. I say this in the interests of full disclosure, (and more importantly to vent my spleen).
I tremble at the idea of running opposite iron man, before whom I kneel and say, he rules this forum. However, Atkins, while a huckster, is not IMO, simply a quack.
I will say from the start that i am speaking from personal experience, always a risk, but so did Iron man. I lost 40 pounds with ultra low carb (did not ever really finish the atkins book, as it was more salesmanship than diet book). I have kept this weight off for 3.5 years and am in fact a participant in the Brown long term weight loss study. (they hate me, because i am the outlier in almost all their studies). Full disclosure: i lost the weight on atkins (not exactly atkins, but no other diet describes what i did better than atkins) but i also exercised quite a bit, and still do, which is a lot easier to do when you are 40 pounds lighter. Very very clearly, ultra low carb is an effective way to lose weight, and very very clearly, it is not a long term strategy (I have added back a limited amount of whole grains, but abhor sugar and potatoes.)
Skeptics need to apply a lot of skepticism to diets in general and the whole low fat dogma that has ruled the dietary chain for a long time, despite very limited evidence. Indeed, the history of the low fat mantra is more political than scientific, and this most recent diet points out what was true for me: low fat is the most difficult way to lose weight.
low carb is at least a valid diet strategy, and in my opinion, unjustly maligned.
Forgive me Iron Man....
