A couple a years ago I did keto for 8 months. During that time I lost 31 kg. While this diet was amazing for losing weight it really affected my concentration negatively, to the point where I was forced to drop the diet because it was simply interfering with my performance at work. It's a real shame though, as I've never been able to find a diet as easy and effective since.
