Obese male starting up

Hey group.

Me:

Age: 46

Weight: 330

Gym level: athletic, educated on fitness and nutrition, diet is shit..

Currently lifting m,w, f. T, th do about 30-45 minutes of cardio.

Plan on starting Reta this Friday.

I've seen posts about lower dosage to start but I've also seen posts where more obese people should start a little higher. Im thinking starting at 2mg.

Mentally I feel like im in a good place diet wise, I've lost about 20 lbs in the last 2.5 months.

Advice would be appreciated!
