I'm taking Mounjaro as prescribed by the Diabetes nurse because I have T2 diabetes and am obese. It's been absolutely brilliant at regulating my blood sugar. More effective than Insulin and Metformin combined, to the extent that only 2 weeks in I was able to stop the insulin and cut my Metformin prescription in half.
As an added benefit I've lost weight and am finding it so much easier to eat low carb.
I've been obese since I was 11, was diagnosed with PCOS when I was 28 but was refused any form of treatment repeatedly by the GP because according to them it was my responsibility to sort out my diet and be less fat.
Problem is, as the blood test have always shown, my body does not produce enough insulin, and doesn't react well to what it does produce, so the only way for me to lose weight was to eat close to zero carbs. Hardcore keto was the only thing that worked even a little bit. So no fruit, no veg except green veg grown above ground, no pasta, rice, legumes, bread.... I could lose weight if I lived on meat and dairy but I felt like crap, my hair would fall out and it was incredibly difficult to stick to.
With the Mounjaro, I can eat a more moderate diet, I calorie count to make sure I'm not eating excessively, I reduce carbs to make sure I'm not spiking my sugars and to stay in the 'low carb' range, around 100-120 g per day, I have fresh fruit and veg with every meal. I've got enough energy that I'm able to swim 3-5 days a week depending on my availability, so I'm building stamina and muscle.
So yes, I think these injections are a massive health improvement for me, and no 'zipping my mouth' has never helped in the past so I see now reason why I would stop the injections and move to an approach that has always failed before.
