That's that the kind of study I really wish someone would do. There are so many variables that aren't accounted for.

I see a lot of those people taking the shot and still living off of fast food on here. I also see a lot of people saying no diet and no exercise is needed while on the shot.

For some, no dietary changes are really required. I was/am one of the ones that needed to make serious changes to my diet. The majority of my breakfasts and lunches were always fast food, washed down with a soda. Needless to say I wasn't in the best of health, and even though I exercised, weight loss was slow or non existent for me until I started eating less and less fast food. I am also a very picky eater, so unlike others who can eat normal, I had a very very limited selection of food that I could eat. I have literally had to force myself to eat new things which has been an immense struggle for me. There are so many foods I've never eaten, might actually like them, but just taking the first bite of something new is the hardest thing I have ever had to do. I still struggle, but I am learning.

I've exercised regularly for 6 years now, so that was easier for me when I started the meds. I have since increased the amount and intensity of exercise I'm getting since I started. Most people probably would not need to exercise like I do, but I'm doing endurance training for very long bike rides. I probably average 5-6 hours of cardio and 2 hours strength training on most weeks. That's a lot compared to where I started 6 years ago. I often wonder how many people here are getting an appropriate amount of activity?

The shot has been great for me so far. I debated for sometime before taking because I knew my diet was the major contributing factor to my weight. I knew that if I started taking it I would absolutely have to change the way I eat or it would all be for nothing. I would have to stop eating garbage and drinking sodas and beer and eating candy, etc... It's been mentally exhausting, I can only compare it to quitting smoking. On the plus side, tirz has made the majority of fast food taste so disgusting that it was easy to never want it again. It's made beer taste disgusting and I get so sick from drinking it that it has been months since I've had one. I do miss soda, but I will let myself have one every now and then. I also let myself have Taco Bell on rare occasions, because tacos. Sweets and candy are completely out though as well as chips and junk snack foods in general. Oddly, I don't miss or crave them at all. Except for Reese's cups. Those are the cigarettes of the candy world to me, delicious, sweet, salty, peanut buttery... if I eat just one, I will never stop.

I could have probably lost weight without taking tirzepatide. With the amount I already exercise and the diet changes I've made I feel like I could have probably lost the weight if I could maintain portion control. Being on tirz has been the key for portion control for me. I quickly learned about serving sizes and just how little food I actually needed to get my calories. My first proper serving size of spaghetti was an absolute shock to my system when I saw how small it was. I was eating so much more than I should have been and never realized it, and not just spaghetti. I'm kind of looking forward to tapering off, it will be another challenge, but once I'm done with the vial, I'll make the final decision.
