*Disclaimer* I only have a High school education

I hope I'm correct in my understanding that different "sweets" effect our brains in a different manner. If "we [our brains] want sugar" we need to give it sugar. Giving it a sweetener [sugar substitute] doesn't let our brain know we've had 'sugar' and it still wants sugar because the fake sugar impacts a different part of the brain then real sugar does..

Clear as mud.....yes?..... but perhaps I've had too much sugar.
