I would suggest going to 6 then 5 days frequency if you have minimal side effects. If everything looks good after a month but you still have food noise, you might want to try the 2 times/week approach but halve the dosage or just a bit more. So if you are at 2.4mg, if ypu switch to 2 times/week pinning, I would go 1.2-1.4mg max
There is also the switching compound approach, or you could add minimum dose of other compound to your protocol see how you respond and according to that increase the second compound while decreasing the 1st. That would allow for an easy transition from one compound to the other
Third option, the harshest, stop cold turkey for 2 weeks then start again at half dose and see how it goes
To be honest, I think the tapering off sema combined with gradually increasing a second compound (tirzepatide) would be the way to go if you are not responsive after 1.5 months at 2.4mg. And increases with tirz, i would go 10% weekly not doubling every 4 weeks as is stated in the proospect
