Bro... you jumpstart keto!! What I did is waterfast for 24hours (wich isn't as hard as it sounds) then start keto, just try to stay under 20-30gr carbs a day. You'll lose waaaaay more than that in 2 weeks.

Couple of things to be mindful of 1. There's somethinh called the keto-flu. Flu-like symptoms when you first enter ketosis. It's an electrolyte and hydration issue. There's a bunch of water bonded to carbs in your body (not exactly right but righ enough to explain) you'll burn the carbs and lose the water. So make sure to dri k way more than you normally do and because your waterintake goes up you'll need electrolytes to keep them in ypur body.

Then just eat however kcal you'd eat to meet your weightloss goal. Just eat them in mostly fat, some proteine and almost no sugar or carbs.

There's a keto subreddit with a lot of tips, tricks, other beginners, with recipes, with motivation! Just try it you won't be disapointed.

I do the keto diet for medical reasons (refractory epilepsy) and I weighed 106kg, went down to 86kg with no effort whatsoever. Trust mw try it, you'll feel better too, more energy, less inflammation, mental stability etc. 

You got this!
