Not contradicting, but your brain is reprogrammable. If you cut things a bit, you won't feel the need to be satisfied. The amount of sugar we eat in modern societies is mostly useless. Now I was "lucky", I fell ill, so I just couldn't eat sugar, now I don't eat pastry, or carbs (maybe 3 times a month at worst). Veggies, tea, meat, fish, nuts, yogurt, can give you a lot.
