I follow the 'classic' diet/regain plus extra pattern.
I've just looked at my data:
June 2016 - 193lbs
Sept 2016 - 177 lbs
3 months to lose 16 lbs, and I did it by slowly cutting what I was eating until I was eating 1000kcals per day and doing a ridiculous amount of exercise. Totally unsustainable.
By Jan 2017 I was back to 189lbs
My next attempt was Nov 2021, when I was hospitalised (unrelated to my weight)
I started at 203 lbs (so had gained 14 lbs in the intervening years without really realising)
April 2022 - 186lbs
5 months this time to lose 18lbs - and again, huge calorie restriction, exercise, the whole thing - to the point my hair started falling out and I damaged one of my knees.
By August 2023, I was back at 212lbs
Both of these attempts also impacted in my family, because it meant 'treat foods' menu choices had to be suitable, so hard there, too. I couldn't have a 'bad' day or a 'relaxed' day out - it's all or nothing.
This time I've started at 225lbs (so again have continued creeping ever heavier)
7 weeks in I'm at 201lbs
I've lost 24lbs in 7 weeks, I'm eating between 1100/1250 kcals a day, doing between 20-30 mins exercise, mostly at home.
It's easy. I don't want the chocolate, the roast potatoes, the slices of bread. I don't want to finish the leftover pasta. I can have a slice of cake for my birthday and go right back to the plan. I want to go do the little exercise routines.
That's the difference. Something in the drug is levelling my interest in food to a healthy point, and changing my metabolism so it doesn't fight the losses in the same way.
It's cost me £260 so far, but I've saved half of that back on food and snacks. Best money I've spent
