If you are insulin resistant, it isn't from carbs - it is from caloric overload. For all they hype on the internet that keto is good for insulin resistance - high fat diets are NOT good for insulin resistance.
Mowglisml had a gentle way of putting it. I'm not gentle. If you are not losing weight then you are either not weighing and tracking your food - or you are weighing and tracking and you know exactly why you are not losing weight.
As complicated as we all want to make dieting, losing weight boils down to two factors that determine 95% or more of the results - caloric intake and protein intake. If you are weighing and tracking then you know where you stand and can adjust. If you aren't weighing and tracking, when you don't get results you don't know why. When we THINK we are trying, but not getting results and have no idea why, I know that frustrates the heck out of me and makes me look for answers anywhere I think I can find them and then when those "answers" are wrong I just quit. I mean, that's human nature. If you do something and it doesn't work, why would you keep trying?
Here is what works. Weigh your food. Log it. This is THE basic skill set for dieting. If you are not willing to commit to this, you are not committed.
Also, as much as everyone says "it's insulin resistance", "It's low thyroid", "it's low testosterone" - I am gonna call BS in 98% of the cases out there. Sure, get tested - it can't hurt to have information. But if I have to put $5 on it right now - the smart money is going to say it's not your hormones because it's not in 98% of the cases. It's simple lack of the basic dieting skills above.
If you weigh and log, and you don't lose weight, you can come back and say, "Hmmm, I didn't realize I was eating 2,800 calories a day. I thought I was at 2,500." Or you will realize, "I'm eating 2,500 calories/day and my weight is not going down! I didn't realize I only need 2,000/day to lose weight." Or, even better, "I didn't realize that I'm eating 2,000 calories/day 6 days of the week - but every Saturday I go out with my buddy and we eat a pizza and appetizers and beer and I didn't realize that meal had 3,000 calories in it and wiped out an entire week's worth of dieting!!"
99% of the time, one of those 3 scenarios come up and a log that is as accurate as possible will help you learn and find it and adjust. Without it, you are floating in the ocean without a map.
