Just to add, the list of ingredients is provided in compliance with law. The rest of the label, is marketing. 'no added cane sugar' can mean 'we use different sugar'. Sugar is also:
Molasses
Golden Syrup
Honey
Maple Syrup
Corn Syrup
High Fructose Corn Syrup
Fructose
Natural Cane Juice
Cane extract
to name just a few ways that the hide it. The list of sugars in the ingredients panel are your best bet. Your other best bet is, if it's 'weight watchers' or 'low fat' or highly processed, you need to double read it to make sure, it probably has sugar.
Dextrose is NOT a low calorie food. It's the glucose half of sugar. So, while it's not addictive, and your appetite control should still work to help you not eat too much, if you want to lose weight, you're better off not eating a lot of it. Sweets are for special treats, not every day. Having said that, the book says that dextrose does not help if you choose to 'wean' off sugar, but if you're going cold turkey, the book says you'll be fine to use it right away. I suspect it might be easier if you don't ( I didn't, nor did I drink diet drinks or eat other artificial sweeteners and had no withdrawal ), but really you can choose your own path, it's not a 'diet' in the sense of a list of rules, there's one rule. Don't eat sugar. Your body will tell you the rest, in terms of not eating too much or too little. I am never hungry, any more. I used to be hungry all the time. I was 102 kg and am now close to 86. It's amazing that getting this result was actually super easy, easier than going the way I was.
Good luck, and keep asking/posting here. You'll have plenty of friends telling you that 'a balanced diet is all you need' ( if 'balanced' includes foods your body does not know how to process, why doesn't it also include eating rubber, or marijuana perhaps ? ). Or 'everything in moderation', which is amusing, seeing as most people who eat sugar, don't do it in moderation, and no-one says to do other addictive substances 'in moderation'. Just stick to it, no matter if you lose weight quickly like I did, or not ( which is common for ladies, who tend to have been trying to eat to lose weight already, and thus tend to not have been eating to excess as I was ), you will feel better, very quickly. People wave chocolates under my nose to 'tempt' me. I can't convince them, I just don't want them any more.
