Anything sweet tasting stimulates the release of insulin. Insulin stops fat burning and promotes fat storage. Artificial sweeteners can be worse than sugar in the way that they trick your body into thinking certain minerals are coming (the only sweet things going waaaaay back would of been fruit) this can then lead on to over-eating and likely cravings...for more sweet stuff.
How do sweetners make you fat? I'm diabetic, don't have sugar, only sweetners, I have no problems with them.
and no, grains are NOT healthy. They are not what they were just 100 years ago.
No one said anything about starving yourself my friend. In the absence of sugars...in their forms, fruit included!!! You can eat as mych as your body asks for. Tons of fat, moderate amount of protein is all you need. So many people are still under the illusion that weight loss, toning up is by restricting calories. This is not so, long term. Its about hormone control. Specifically insulin. Keep insulin low and you cannot store fat. Raise insulin...and sugars do this better than anything and your body goes into fat storage mode. Don't starve yourself, eat until you are wonderfully satisfied, without guilt..but of the right foods. Exclude sugars, FRUIT, grains, starches and sweeteners (everything that provokes an insulin response) and fill your boots with everything else. Tis life changing, body and mind. P.s self control in regards to diet is near impossible for those who eat refined sugars due to the sugar rollercoaster and moods/cravings it brings. Walking will not reveal your 6 pack...although...for those who cannot perform hiit or resistance training will help, lowering cortisol the stress hormone that also keeps people fat.
