I've been 30st, went down to 18stone. It was in the early days of the jabs so I didn't use them (I have absolutely no problem with them and will probably use them to continue to lose weight if I feel the need too, at the time I just wanted some others to be the guinea pigs 😂) and weigh loss surgery wasnt right for me, I firmly believe you need to be in the right headspace and I wasn't, I know I wouldve fucked it up.
I started small, the first week I ate 1 chocolate bar in a day instead of 2 or 3 and moved more...I got a bin bag and picked up all the rubbish in the house and cleared my wardrobe out, I tidied the kitchen cupboards, walked to the next bus stop instead of my usual, walked to Tesco instead of Sainsbury's because it was slightly further
The next week I tried to make a healthier choice for one meal of the day (it was lunch in my case, giant salads with enough stuff in that it felt substantial...it was never going to be as many calories as 2 McDonalds meals with apple pies and an extra cheeseburger which was my go too)
I spent a month making small changes like that but they added up, then I started calorie counting, not restrictively but it had to fit in my calories (I used my fitness pal) and built up the walking.
And my biggest thing was if I had a bad day, I just started again the next, no beating myself up or "I fucked it up so now I'll REALLY fuck it up". Just oops, lets start again.
It's not easy but it IS doable, I absolutely promise
