When I was doing my "Nazi anti-sugar", I made peanut butter balls using stevia. They came out tasting okay, but the sweetener didn't react the same as refined sugar, so the peanut butter mix was too soft. My solution; I added flour. That turned out to be a big mistake. After eating a couple I had bad stomach pains. After some research I found out it's not safe to eat raw flour. It's supposed to be cooked in something.
Being stubborn, and in love with peanut butter balls, I restricted myself to one per sitting. It still caused a slight discomfort in my belly, but I ate them all. Haha
Point is, although I drank my coffee black, I used stevia a lot and did not get the aches and pains caused by sugar and carbs. I'd actually make Kool-Aid using the non-sweetened pouches and 8 teaspoons of stevia rather than drink ultra-sweet apple juice, cranberry juice, grape juice, etc..
Quick tip: Your body burns fat and glucose for energy. Glucose is MUCH easier for your body to burn. When you eat carbs, your body converts that to glucose (at about a 1:1 ratio I believe, not 100% sure). That's why carbs are bad. We all have excess fat on our bodies because when we eat, we take in sugar, fat, and carbs. The body burns the sugar, then the carbs as glucose, and stores the fat for later use. "Later use" never comes because we eat more sugar and/or carbs, and store more fat. See the trend?
When you go a length of time without eating, let's say over night, you feel hungry. This hunger is the body telling you to eat sugar or carbs so it can get easy energy rather than burn fat. If you ignore this for 15 minutes, it goes away, because your body has now switched to burning fat. About an hour later your body will try again to get you to eat. Ignore it and it'll go back to burning fat. This is what happens when you fast, and why you drop weight so much faster when fasting. It's not just calorie restriction, it's forcing your body to burn fat.
The keto diet (which I don't do, too picky) uses a similar effect. Cut sugar and carbs so even when not fasting your body only has fat to burn. Your body becomes a fat burning machine, which they call ketosis.
*Not mentioned is the burning of protein. My research never reached that point, but I believe a small amount of protein is used in burning the fat or glucose, and it can be burn if fat or carbs are not available. Not sure.
Based on this info, imagine how bad ice cream. And my favourite desert is a root beer float! lol
