How to lose 7 pounds by today?

I weigh 50.7 kg now and I want to be 50 kg so I want to lose 7 pound by today and keep the weight off as well

Where yuu dont eat anything and yuu drink water

Honestly you look good to me. you want to be a model or somthing?

I think you want to lose 700g, not 7lbs; 7lbs is approximately 3.2Kg.

Do you know 6st is only 38Kg? It's like the weight of an ten-year-old.

At 6st you are extremely underweight; you have a BMI of 15.4.

BMI Categories:

Underweight = <18.5
Normal weight = 18.5-24.9
Overweight = 25-29.9
Obesity = BMI of 30 or greater

What!? 15.4 is less than 18.5; that makes you underweight.

50.7Kg is roughly 8st which puts you in the healthy range.

Why would you not want to be healthy?

I'm sorry, but all these conversions are giving me a headache; I think 8st is good and 6st is bad; you want to weigh less than me and people think I'm anorexic.

I think I may be implying that you have an eating disorder.

If you think you're obese you obviously have some problem... im going with some sort of body dysmorphia, and your unhealthy attitude towards food could lead to an eating disorder...

50.7kg is 111.54lb = that's BMI 20.4 for you.
BMI 18.5 - 24.9 is in healthy range.

like it has been said 6 stone [84lb] is BMI 15.4 for you.
under BMI 18.5 is underweight, so 15.4 would be very underweight.
if you have the symptoms of anorexia and have a BMI of 17.5 or less than you are anorexic.

I do understand you wanting to be 84 lb [6 stone].
that's my ultamite goal weight.
I'll be BMI 15.56 at that weight.

you're not underweight at your current weight.
