I agree that HFCS is a bad thing. It's concentrated and devoid of fiber (and plant protein). The fiber is the magic that hinders absorption. That's why I recommend blenders over juicers, as the latter strip out most of the fiber. The juicer camp will argue that the fiber also hinders absorption of nutrients contained in fruit, but I don't really see the need for ultra concentrated nutrients, especially since our bodies are adapted to eating fruit in its natural state :-).
I know there is a lot of interest in low carb diets these days (an obvious backlash to three decades of low fat dieting), but there are body types which are well adapted to a high carb diet. Dr. Mark Liponis has a great book on this subject (https://www.amazon.com/dp/1401935540). In my case, I'm clearly a "farmer" and lose weight on a high carb diet, while my wife is exactly the opposite and gains weight on a high carb diet. It all depends on how your body reacts to carbs, and it can actually be tested via reaction to consumption of sugar water.
i agree and have read lots of research about eating high carb diets, specifically, high fruit diets.
but a lot of the people ive talked to in that catagory burn lots of calories also.
I can see a scenario of someone who does not burn a lot of calories
and eats a high carb diet not doing well.
Especially with some of the super-high brix fruits.
But looking at it from another perspective
taking away "empty" / low-fiber carbs like white bread and pasta
and eating fruit instead i think is a win-win.
