and i know what a Keto diet is and i dont recommend it, seems to me you're looking for changes over night with as little work as possible and that wont happen, you wanna avoid losing the muscle that you have right now. So i recommend about 1.5 - 2.0g of protein per pound or per every 1/2 a kilo of body weight. Then you wanna have just a little under that in carbs, and i like saying under 70g of fat. It's the way i've been doing it and ive dropped some weight in the past month.
