Interesting, a few years ago I was needing to lose another 10- 15 lbs and my brother who is 2 years older was diagnosed type 2 like both my parents and he was maybe 10 -15lbs overweight. By eating better and lifting some weights but no cardio to get to that 10-15 lbs needed when I looked into intermittent fasting and 6 to 8 weeks later I lost that 10lbs. I didn’t always eat as good as I should've either. Decreasing your insulin resistance is key and the 16 to 18 hrs of not eating helps that even if you don't eat great. Having said that carbs, grains, starches, fried foods/seed oils all increase insulin resistance. I have cheat days but eat good most days. Supplement with vitamins/minerals to fill the holes in the diet. Drinking, taking drugs/medications, eating processed foods which is like 80% of food in stores all deplete these in the body. The soil the real food is grown in also has been depleted so it is hard to get the needed amounts. Then you have the synthetic vitamins that are used in supplements so it isn't easy to get everything needed. Nice talking to you
