Hello I’m 28 so recently went to the doctor I weight 190 and 5’5 tall I was told I need to loose weight he said “I would honestly like you to get down to 135-140 reason being I was born with one kidney and my weight is effecting how well my kidney is functioning

Honestly idk how I’m gaining weight I really only have time to eat once a day in the morning I’m rushing to work never grab breakfast and after work I’m so tired from standing all day I just want to shower and go to be so I’m literally just eating lunch

Any advice?! I’m willing to try just about anything to avoid being on dialysis
