Losing weight and keeping it off. (long)

[Blondielongie]

Back story. I lost 3 stone over 2 years. I got down to 8.5 stone. I kept it off for about 6 months by eating 1200 calories a day. Then after a holiday, I went back to 1500 give or take. Just over a stone has crept on since then (a year ago)
Do thin people have to constantly diet? How do you keep it off
?

Also, I've lost 4 pounds over last 2 weeks by eating 1200. On Saturday, I had 2000 and three pound has come back on. I've kept track of water and weigh myself same time/same outfit each day.

I'm prepared to be told I'm overly invested in this, but what is the science behind it? Does everyone have a weight they are meant to be and mine is 9'8? I am 5 foot 6. Weight is all on my thighs.

I've posted recently about the baffling nature of weight loss and it not being a linear science. Just wanted to say you are not alone.

I think I would say you probably have to take a longer view on the 3 pound gain. And watch for a trend over some weeks.

Well done on the weight loss last year!

At 5'6" and 8st5 your BMI was 18.8

At 5'6" and 9st8 your BMI is 21.5

BMI healthy range is 18.5 to 25 - with a BMI around 21.5 being the perfect ideal weight which is smack in the middle of healthy. At 8st5 you are edging close to underweight, a position your body is likely to find biologically non-ideal.

Fatedestiny is correct. If you are at a low weight for you (and BMI of 18 odd is pretty low) it will be hard to maintain. Ps daily fluctuations mean nothing. My weight varies by a couple of kilos depending on whether I ate loads of carbs (make you retain water), time of day, hormones, whatever ...

Thank you. Glad I'm not alone. Yeah I suspected that it's unsustainable. Annoying that o have take friends who don't have to watch what they eat. (they haven't had kids though!)
