OK, when you store fat, your body converts glucose, to triglyceride, to glycerol, to FAT! Glycerol and glycerine are interchangable words, they are a sugar alcohol and don't raise insulin level, but are one metabolite away from fat. Glycerine is used to sweeten and moisten bars, and does not have to be included in the carb count, but it does have to be in the calorie count!
So take your bar, (the new WWS Lemon is really bad, so are Biochem bars!) add up the P, C, And F at 4, 4, and 9 calories respectively. You will be left with 40-75 calories of glycerine. Divide that by 4.3 and you get grams of glycerine, usually 10-18!
Anyone on a cut will become leaner within days of giving up bars! I have done and seen this many times, especially watching guys "BLOW UP" post contest!
