I get this all the time. I was about 50lbs over weight and got complimented all the time. After some major events I lost those 50 lbs. I'm currently 5 foot and 107. I'm well within my healthy weight, but now friends and family are expressing concern that I'm anorexic, I get daily phone calls just to inquire whether I've eaten and what exactly I've eaten. The only time I get positive feedback is if I happen to eat a sweet or splurged on a huge meal, otherwise it's a lecture about starving myself. Health issues have kept me out of the gym so diet is very important to me, I just eat very clean and most of the time I'm eating very keto, I think that observation is what confuses most people. The way I live is how most people crash diet.
