Is 745 calories a day sustainable?

[Anonymous]

I was able to drop my bmi from 21 to 19. I’m tryong to get under 18 so I downloaded this app yada yada and it said to lose the weight I want I’d have to eat 745 ish calories a day. Will that harm me or can I make it work?

You’re going to have no energy and be malnourished at 745 calories a day.


It sounds like your metabolism is seriously slow.


I’d suggest taking a break from dieting and spending a year or two repairing your metabolism first.


Once your metabolism is healthy, then it’s safe to systemically go into a caloric deficit to drop body fat.


You should check out this resource from a certified personal trainer and dietitian on reverse dieting:

No. You need 10 calories per lb. Of weight generally just to live and breathe each day. And if you do anything to burn any calories, if you get out of bed, you're going to need MORE!

So unless you're telling us you weigh about 75lbs. That's not enough.

i will not be giving advice to an underage girl who is clearly showing signs of anorexia (getting under a bmi of 18 is underweight).

you clearly know it's not sustainable. you will either ruin your body (malnutrition, getting sick when introducing foods again) or gain all of the weight back because you're starving.

as a healthcare worker, that is not sustainable or healthy. in effect restricting calories can cause you to gain weight. it will cause more harm then good

It’s fine, if you are fasting. Yet, you shouldn’t do too much exercising, but some small stuff, like planking seems to be fine. Little energy is spent by holding a plank, although lots of force in the abdominal muscles.

Way too low. Even a baby cannot live on that. Eat some 400 cal below your BMR x activity level.
