Carbohydrate and sugars are not our friends when it comes to weight control. There are lots of people who say the obesity epidemic we are witnessing now is due to the high sugar and carbohydrate diets that have become mainstay of western diets over the last 50 years. Have a read of "Sweet Poison".
I have been on a high Protein (about 100g / day) and low sugar diet for the last 7 months. I have lost 41 kilo. Whatever sugar that is in the protein rich foods I eat that is what I consume. My Protein shakes have about 10 g of sugar, the Protein Bars have about 4 grams. Whisky has some sugar as well. I keep my calories below 1000 per day - I usually like to keep them around 800-900 per day. Ice-cream = no way, chocolates = no way, sugary drinks = no way, chips = no way.
