Yes I agree, you should check out full keto or LCHF. Most of the stuff in those delicious images up there is pure keto, most of the best tasting items anyway. :) So just skip the french fries, rice, pasta and dessert. Eat more fat. At least read up on it, lots of material on the internet.

But as you read, bear in mind to be suspicious of fanatic vegans claiming keto is the worst thing ever. Why? Because they want ALL meat eating to stop. :)

But keto isn't the exact opposite of veganism, it's entirely possible to eat SOME veggies on keto, just not too much of the sweeter ones, like carrots, tomatoes and corn. And it's possible to get by without eating a ton of meat too, I use low-carb protein powder mixed with heavy cream... tastes like dessert. :)
Oh and also check out IF or Intermittent Fasting.
