I started eating Keto 14 months ago. I’m back to size 12 having crept up to almost 16 and have far more energy and hardly any aches and pains.
I find Keto easy to do and not expensive as I’m not eating as much! A mug of fresh coffee with MCT oil and cream first thing, one main meal a day of meat, fish or eggs with veg or salads, maybe berries and cream after, a snack meal of egg, cheese or a Keto mug cake with cream, a few nuts and 85% chocolate. Quite cheap really as those foods are filling so I don’t crave more.
