About two years back a friend of mine got me into Keto diets. (See /v/keto ). I'm 160cm and went from 72kg all the way down to 59kg. I'm at about 61kg right now and have stabled out at that for over two years. I eats tons of cheese, fat, meat, veggies -- just little to no bread, pasta, fruits, juice, etc. It's been life changing.
