<human>: Can you provide a brief rundown of the text in within 3 sentences?

My mom [5'2", 132lbs+] is trying to sabotage my [5', 91.7lbs, NOT  underweight by my Asian country's standards] attempts at healthy eating and getting fit. I count my calories, and try to stay under 1400/1500 calories just in case I underestimate.

So I've been working out and lifting weights, and unintentionally lost a bit of weight (11lbs) in the process. She thinks I'm deliberately trying to lose weight. 

Her comments are insensitive and uncalled for, and she does it every. single. day. To my boyfriend as well, who works out regularly and is lighter than her at 5'6.5".

* "Your face is so sharp and ugly now, and your collarbones are protuding. You need to gain weight." Says the person who told me to lose weight at 105lbs. 
* "Your skin is so yellow and you look so sick, you need to gain weight." Didn't know my mom was a doctor.

I've been going to the gym, and she keeps telling me it's a "waste of time" and I should be studying. How funny, she doesn't tell that to my brothers who gym more frequently.

My father is on her side as well (overweight, high cholesterol). Apparently, I can't have foods I dislike or not feel hungry when they're hungry. She thinks she knows what's healthy and what's not LOL what a joke. The funny thing is that she's overweight (plus sedentary) and blames it on her geneticks while my brothers and I are all on the lower side of the normal BMI range. 

I think she's insecure and trying to sabotage my efforts just because she won't move her ass and lose some weight herself (she has mentioned she wants to lose weight many times, but "loves food too much"). I used to be the fatter one. She sabotaged my dad's attempts at losing weight as well. She gets so defensive when I call her out on her excuses.

How do I get her to stop being so insensitive, assuming shit and sabotaging people's attempts at getting healthier??? 
Thanks.
<bot>: Overweight mom is trying to sabotage my efforts at eating healthy and getting fit, hurling insensitive and unnecessary remarks, probably because she's insecure herself.
