Types Of Artificial Sweeteners

Or is there not much difference between them?

And I heard that artificial sweeteners may inhibit weight loss, does anyone know if there is some truth in all this?

Strangely your body can react the same way to artificial sweeteners as they are real sugar. I do not think so, but some of my friends with diabetes have confirmed that they had to pay close attention to diet pop as their blood sugar spikes in the same way he did if it had been normal . Does that further weight gain as well, not quite.

The longer you keep indulging in sweet things, the more you'll want them well. I know this is not what you wanted to hear, but the best thing for weight loss is to avoid sugar all together. Drink water or tea instead of juice or soda (diet or regular) and you'll be much further. Since I stopped drinking soda (from 2 to 1 a day every few weeks as a treatment), I have less cravings for sweet foods - both real sugar or diet. If you want something sweet, eat fruit. This is a big adjustment, but becomes much easier as time passes.

Artificial Sweeteners: sugar-free but not without risk

Well the most commonly used artificial sweeteners are aspartame, saccharin, sucralose and neotame. People take them to the place of sugar for weight loss or because they are diabetic. They have no nutritional value and they have by-products of harmful toxic side effects. These artificial sweeteners contain chemicals that have potentially harmful long-term consequences.

I do not know about the issue of weight loss. Have you tried Stevia? It's supposed to be a natural sweetener.
