LCHF for ke memas low carb, healthy fats.
Eg olive oil, avocado, eggs, the fat that comes in meat rather than around it, full fat dairy (ie not low fat versions).
Making sure you have enough healthy fats stops you feeling hungry for carbs
LCHF for us means low carbohydrate high fat, and this diet replaces higher volumes of carbohydrates with more fat for energy/fuel, since it's the carbs which tend to be the major issue in raising glucose levels for many T2 diabetics.
I'd agree with @MrsA2 that the high fat means healthy fat, which for me is normal full fat food instead of the reduced/low/lite fat offerings with their natural fatty goodness removed - but it doesn't actually require me to stuff my face full of lumps of lard, etc...
would you please tell me which diet or meal plan i should follow like carnivore or keto im kinda the same im fit aswell but been in prediabetic range any advice to stop myself from getting worse would be nice
