This is a decent start, and I’m assuming much more than you’ve been eating.
But you’re gonna need more. Plain and simple. Start here. Track your gains. The scale is a tool. Not an end all.
Measure circumference of each arm, leg, waist and chest now. The remeasure in several months.
Pictures tell a better story.
When I say you’re going to have to eat a lot… I mean you’re going to have to push up to 4000 cals or more.
Since you have said you normally don’t have an appetite this will probably be better than what you’ve been doing but expect to increase those macros… a lot.
