Another low carber here - I have lost two stone slowly and gradually over 4 years ( plateaued a couple of years ago, and not gained since then) .
The real culprit is sugar, and all carbs turn to sugar in your blood, excess turns to fat ( and diabetes for some).
Once adapted ( after a week or so) you lose all your sugar cravings, so perfect for those who can't leave the bikkies alone, you will feel more energised, and mentally awake. Some people claim their arthritis improves, because sugar causes inflammation in the body, and arthritis is basically inflammation of the joints.
It does take a bit of determination to begin with, and you might suffer temporarily from 'carb flu', but that will pass.
I don't find it difficult to do, as my digestive system doesn't seem to like high carb foods much, and I don't really miss those foods any more.
