Over a four months period, after starting Paleo I lost some twenty pounds, and got to optimal weight that I have effortless kept since then. Last week I was talking to a friend of mine, who is a doctor and eats decently well (though not paleo) and he insisted that my weight loss should have come from caloric restriction: he claims that by adopting paleo I was eating much less calories, since I dropped wheat, pasta, pizza, bread, sugar, etc. My question (beyond this anecdote) is the following "do we have evidence that in fact paleo is better in terms of weight loss than a diet perhaps similar in calories (though not as healthy) " Please do not tell me that "paleo is much more healthy" since I know that, and I practice it, searching for optimal health, not just as a weight loss method! anyway I am curious to know how to answer my friend´s view: that my weight loss was the result of eating LESS calories not necessarily of eating Paleo.
