I don't have any professional expertise to dispute these references (so I won't), but my own experience is that, in excess, food of any category (and I eat, or have eaten most of them in my time) will cause me to gain weight. This is a complex area, and it can get very confusing when the myriad physiological and psychological aspects of seeking or shunning particular foods get mixed together. I would only remark that it seems on the face of it a very difficult proposition to carry out a rigorously controlled experiment capable, at the same time, of discriminating the specific effect of limiting specific food types (e.g. carbohydrates) from the overall energy economy (including, of course, output). It is also a common-sense observation that people worldwide and throughout history have been capable both of sustaining life and health, and controlling body composition (or not) with an almost inconceivably wide variety of food sources. In view of these aspects I personally find it more reliable and effective to focus on overall energy balance as a first priority and select food types to choice and taste as a secondary, albeit important, one. I should emphasise that I intend these comments to apply only to the question of weight control, and not to other health issues where choice of food types may have specific relevance.
And those of us in the Low Insulin school, don't follow Calorie In Calorie Out.
The Body doesn't boil down to a simple Physics problem of fueling a furnace. The Hormone Insulin enters the picture, and affects Fat loss.
Fasting places the body in a low insulin state.
Low Carb diets work for the same reason.
