I lost six and a half stone and have none.
however I worked out throughout, moisturised all over daily and consumed enough protein to protect my muscle and lose fat instead, lost an average of 2lbs a week, and always drink 3 litres of water a day. In the weight loss phase I never went below 1g of protein for every kg of body weight and was often at 1.2g.
I had some wrinkly upper arms, a little saggy /looseness under my back side and some crepyness on my tummy when I twisted, when I hit goal. I then went straight into body recomp, which was basically continuing the work outs, but upping my protein even further as I could now increase my cals, I went to 1.5g per kg of body weight, and it just all tightened up and went away, now I have none, I’d say I noticed a difference within 6 months and a year for it to go fully.
I’m in my 50s. It was odd, when I first hit goal you could see I’d lost weight, I was worried about going on holiday and swimwear, I looked a little deflated and thin. Fat goes really soft and sort of pliable when you’re losing weight, which adds to the illusion, but when you stop it firms up, which changes the look again.
but now nearly 18 months later, still the exact same weight, I look fit with muscle definition, no lose skin, you’d never know I lost weight, my daughter actually said to me you just look a normal weight now like you’ve always been like this.
I’m 9 stone, bmi 20, dress size 8.
I think a lot comes down to genetics, how long you’ve been over weight for,ie how long the skin was stretched, how rapidly you lose weight, how well you lose it, ie do you protect your muscle and lose fat, how much do you work out, how much protein do you consume, what condition is your skin in, do you moisturise daily,how much weight did you lose etc
of course there are many people who lose and will always have lose skin, but it is certainly not a given for many, it wasn’t for me.
