I was like this during the summer, I binged on crisps and chocolate during lockdown, didn't do the daily exercise I just melded into my couch and got fatter.
I weighed in at 16st2lb at the beginning of August which was depressing, I also looked like the blob with no neck and 5 chins in all photos.
I started logging everything I ate and drank in my fitness pal, the first week it was just a tracking exercise to see where I was going wrong. Turns out I was eating twice the recommended calories and about 80% of that was refined carbs like bread, pasta, chocolate, sweets, crisps. It was easy to see that the only outcome of that would be to get fatter.
I have PCOS and insulin resistance so knew that the sugar was doing bad things to me, I had regular thrush, frequent urination, felt tired. I knew I was on the edge of diabetes I just didn't want to think about it.
I cut carbs down but not out, bread once or twice a week, pasta once, chocolate/crisps on rare occasions. Swapped for green veg so green beans or asparagus instead of oven chips for example.
I added 3 x 30 min workouts a week using the couch to fitness programme by OurParks which is free and starts easy then gets harder, or C25K depending on what I fancy doing.
It's now 3 and a bit months of doing the above and today I'm 13st13lb, I've hit and exceeded my first big goal which was to move from obese to overweight and I'm making progress on hitting my next target which is to get to healthy weight.
What keeps me going is weighing daily so I can see the scales move, taking pictures at the beginning of each month so I can see the improvements that you don't notice in the mirror and being able to do more, I can run in the park with DD now which I couldn't do before.
Here's my face progress pics, if I hadn't done the pictures I wouldn't think I looked any different as you get used to your reflection bit by bit.
