FFS. Tens of thousands of people successfully lost substantial weight, and kept it off for years, by using Sema or Tirz according to the basic pharma protocol.
Here we have the most effective solution for durable weight loss and significant improvement to every aspect of health, basically as close to miracle drugs as was ever discovered, and you want to reinvent the wheel by jumping on then off a GLP and expecting that to work.
Get on one of the fucking GLPs. Titrate up according to the pharma protocol, and discard the notion you have that they're diet pills and not hormones that boost the level of what you're lacking, like insulin for a diabetic, and can be stopped without your dysfunctional appetite causing you to regain the weight sooner or later,
You're already in a great position because you know the importance of protein and resistance training. Just get your metabolic hormone deficiency corrected with a GLP, silencing the "food noise" so your conscious mind will be in charge of what you eat, and you'll be good to go.
