low carb?

Hello!

So this is my third time trying losing weight, although I lose successfully 30lbs 3 years ago but gained it back plus more after two years of mental health issues. I'm pass that time in my life and I want my body to match. When I lost the weight the first time I just didn't eat over my allowance but ate whatever. I feel as though thats the reason I was 30 lbs lighter but still have a huge stomach. I carry a lot of weight around my stomach and face and I'm already pre diabetic so its literally now or never and I'm very motivated.

I heard that low-carb diets helped with burning fat and I just wanted to know if anyone knew if this was true? I cannot afford a nutritionist so online is my only resource at the moment. I tried eating low carb anyways but I find it so hard. What foods have low carbs? I find myself going over even when I try to eat the cleanest and adding more produce than other food items.

Thanks!
