have some suggestions...  I  started Keto Jan 1st... (started 37 BMI)... lost 10 lb first 2 weeks... then Plateaued losing only 2 lbs next 5 weeks.... researched online and 2 suggestions helped me start losing another 8 lbs in the next week and a half.  I also was fasting, and so much, I started the OMAD routine (One Meal A Day) this didn't help, but what did... 1) started doing more of a carnivore diet.   2) Had my doctor change medication I was on that was know for weight gain and keeping me from loosing weight.   I got this information from Dr Berry, ( a Keto Diet enthusiast) and real MD.  I will attach a youtube link to a video that he tells of the meds you should not be taking if trying to lose wieght.

How long have you been on the diet?
