In my late teens and early twenties I was on a high carb/very low fat diet. I thought I felt pretty good, lost weight, but I also never lost the fat around my midsection. I ate an incredible amount of food and I always felt like I was starving. I'd get sick if I didn't eat by mealtime.
A decade later when I tried lower carb (most carbs coming from veggies and fruits) and didn't worry so much about healthy fats, my middle shrank
dramatically. All that fat that was packed around my internal organs was gone. I also realized how important good fats were *for me* and my emotional well being and cognition. Plus I didn't feel like I was starving all day anymore and I could wait a half hour for my dinner without nausea, sweats and the extreme irritability my Dh came to understand as a sign I needed food.
I don't have insulin resistance, but I do feel I need to be careful as diabetes is prevalent in my family and I have experienced issues with hypoglycemia while eating carbs. Having had the experience I've had, I will never go back to a high carb diet again.
That's just the way my body works. It's way too individual to say one way is the answer for everyone.
