Weight loss is something like 90% down to your diet, so the first thing I would do is look at cutting back so much exercise ( unless you hugely enjoy every second of it, but you say you’re exhausted) and count calories like a MF. You don’t mention how much you’re eating - you say a lot but have you checked your TDEE and gone down about 500cals below that? Cut out alcohol, sugar and refined carbs, drink a couple of litres of water a day and prioritise protein and fibre in meals.
To be fair, that’s the life of most people on WLIs - the drug increases satiety and slows gastric emptying, it doesn’t make you lose weight. There seems to be a lot of misconceptions around this area. WLIs make you feel that it is physically impossible to carry on eating past the point of satiety so you naturally eat less, and for some people there comes less interest for greasy or sugary foods. But it would still be possible to make bad food choices on Mounjaro and sabotage your own weight loss.
I also think age has a lot to do with the amount of weight people seem to lose - I see a lot of women in their 20s and early 30s on social media who are shedding weight fast - but then so could I at 25 if I went down to 1000-1200 calories a day. Your metabolism takes a hit as you age, so if you did everything above AND used a WLI, you might hit a 1-2 pound loss per week. Which is the recommended target to avoid gallstones, loose skin etc.
Im not trying to gatekeep the stuff, I’m on it myself. I’ve been overweight my whole life to some degree or another. Using it doesn’t stop me fancying chips, for example. But my weight loss has increased when I make better choices about the food I eat, even if it amounts to the same calories I stay within each day. And fundamentally, when I look at my family and my ancestors, we have all been short chunky peasant stock for generations -I have the DNA and fat stores of someone who needs to survive freezing Highland winters on nothing but neeps and tatties and the odd rat. You can’t outrun your genetics.
WLIs are not to be taken lightly. By all means lie on your form, exaggerate your weight etc in order to be approved. But be aware you’ll most probably need to be on it indefinitely to keep the weight off. Your life won’t magically transform by losing the weight and then you can just go back to how you were before because you will immediately put the weight back on if you haven’t used the time on mounjaro to reorganise your attitude to food. We all need far, far fewer calories than we think we do, which is the depressing truth of the matter.
I recognise that my attitude to food is disordered and am using my time on MJ to help with that. But I also know that I will probably have to be on it forever because I have deep rooted issues around eating that won’t just be solved by losing four stone either.
