Low carbs special effect?

Although you might see the weight come off initially, once you start eating carbs again you'll gain it all back. And you will eventually start eating carbs again because a low-carb/carb-free diet isn't sustainable at all.

can you explain this further?
I'm not crossing my set calorie intake at all. Will something go wrong if I start eating carbs again yet I'm still under my calorie goal?

Oh and my weight is 205-210, 5'8 height, 19 yo.

If you're not doing some form of moderately intense exercise and are instead cutting carbs to lose weight, then once you reintroduce carbs into your diet you'll gain the weight back. Carbs are stored as fat when they're not used as energy, so if your body is not expending them as energy to fuel workouts then they'll be stored as fat.

What is Glycogenesis and what is DNL?

From what I understand about carbs from a nutrition course I had to take is that there are two kinds: refined (things like white bread and pasta) and complex (whole grains, wheat ect)

Ask for your money back. Simple carbs are small molecules like sugars, complex carbs are large ones like starch.

"Refined" is an ill defined weasel word that may mean the fibre or other impurities have been separated out.

Does anyone actually eat whole grains ?

I'm going to have to disagree that the low-carb is over-hyped. Or shall I say, low-grain. There's a lot of research out there that points to otherwise. If you look at all your fit Hollywood people, they all generally say the same thing: they follow a protein-rich, vegetable-rich, low to no grain diet.

I have never been an over-eater per se. But keeping grains to a minimum (i.e. one meal a day) helped me get 20 pounds off and maintain that weight for five years. If I "screw up", I see it on the scale, and I also feel lethargic. Some say 1200 calories is 1200 calories. But you can eat a lot more food @ 1200 calories if you're eating clean and unprocessed foods.

I wouldn't say that "fit Hollywood people" counts as "a lot of research".
