@lucifargundam I started overhauling my diet in May of 2019 (I was also pre diabetic). I chose to go the keto route. The withdrawal from carbs wasn't fun, but I've felt better ever since.
Tips to prevent snacking:
1) drink plenty of water
2) if your hungry eat an actual meal
3) keep your blood sugar steady
The last one is key, and the hardest to do. If you choose foods that burn/store quickly the resulting blood sugar crash will leave you hungry. Does that make sense?
@lucifargundam I have one and did use it a lot at first. Now I use it occasionally if I'm curious. I also used a macro tracker at first to make sure I was keeping my carbs low. I'm still 0 sugar. We now use a natural sugar substitute for special occasions. You will have insulin rise every time you eat. However, have that daily chart look like waves not mountains, it is what worked best for me. I also didn't go on a diet. I decided on life long food changes.
