It's not easy but you have to be almost militant like
-cut off all sugar, no exception.
* I use stevia sweetener as a replacement for my coffee
-intermittent fasting.
* I stopped eating 7/8pm and I don't eat for 16 hours straight.
-low carb lifestyle
* white rice, bread, pasta, potatoes are the worst!, if you must eat, make sure it's in small portions.
* vegetables like broccoli, cabbage, mushrooms etc should make up big portion of your plate
there's also so many low carb products like keto breads, atkins snacks (they have goat chocolate bars), frozen dinner, etc, doesn't hurt to stack them up.
last but not least (exercise), I'm horrible at this but it's the best medicine in keeping a good blood sugar level, specially if you just ate high carb foods and you want to avoid spikes.
it's not easy but all it takes is 3 months of dedication and everything I stated will become 2nd nature.
