OP, I started WLIs a year ago at age 40. I had thirty years of dieting experience behind me (yes, I started dieting aged 10).
In those thirty years, do you think I never tried eating healthier and taking exercise? I tried EVERYTHING. From skipping meals (now called intermittent fasting, but in my teens it was just not eating all day and pretending I wasn't lightheaded and dizzy), to Slimming World, Weightwatchers, getting a personal trainer, low calorie, low carb, Herbalife, shakes, the Fast 800, all sorts of fad diets and so-called 'lifestyle changes' and habit resets. I've had gym membership and various personal trainers since I was 16.
I had a BMI of just under 42 last June. I started taking Mounjaro and I've lost over five stone in a year. My BMI is 29.
In that year, I have continued with the personal trainer I signed up with two years ago so yes I have been exercising but I already had been. I have eaten very healthily on the jabs, but I have also tried healthy eating (and not so healthy restriction and bonkers regimes) many, many times before.
The jabs have made the impossible possible. It wasn't for want of trying. I tried so hard all my life to lose weight and keep it off. Nothing has ever worked the way the jabs have, and the more diets I did, the less they worked. Yes, I have lost weight countless times in my life before regaining plus extra, but it has never been so straightforward and consistent and effective as the jabs. It felt like Mounjaro turned a dial and set my body onto 'normal'. I can't really explain it any better than that.
