7 years ago I discovered keto and I lost 20kg in a year. The great thing is you can always eat as much as you want and you still lose weight if you stick to extreme low carb even without any exercise at all.
I do not live alone and the others are not on my diet, so there's always temptations around. Chocolate, Nutella, cookies, cake ... and I had gained 10kg on these temptations but with discipline I'm currently at -15kg.
