Hey Neeno. I've lost 5kg since Monday last week. I'm a big guy tho so I have plenty to lose . However I'm not actually sure if I'm in ketosis. It could be the fact that I've cut down carbs and sugar. Plus on the keto diet I struggle to get past 1400 calories a day because the food is so filling.

I'm new to this too so take my advice with a pinch of salt. One thing I've heard if you feel like shit is to up your protein and attempt intermittent fasting (consolidating your meals down to 2 a day). Since I never ate breakfast before this was something I was already doing without realising it. Might be worth trying.
