Not sure why you want to get to 220, at 6'3 with all the cardio and strength training you do you should look lean @232. Matter of taste but 220 sound skinny for 6'3, except maybe if u are in single digit body fat.
I am facing a hiuge wall in the 216-217 area trying to hit 210 as next step. My keto was so in and out thanks to 5-6 weeks travelling outside of U.S. and eating some damn good food. But to my credit I was 215ish end of June when travels started to I held on despite some great eating displays and cycling back into keto and then repeating haha. I have not done any lifting since I have been back and 1 outdoor soccer game so I am in need of a kick in the ass...hope to snap out of it soon.
All you need to do is to once again start doing all the things that got you to 215. You've plateaued because your discipline dropped once you started traveling. Get back to lifting. Get back to basketball and soccer. And get back to keto. If you don't do it soon, your weight will explode back up before you know it. Don't let all of the effort you put into losing weight end up being lost because of temporary laziness.
If I may chime in with my 2 cents. (Ten cent value!) The more willpower your dietary regimen requires, the more drama you will have in your life. Willpower requires mental energy. The more willpower you need, the more that energy will be depleted. It may well affect other areas of your life quite apart from your diet. That's why I'm convinced that sustainable eating plans are best in the long run.
This advice may have 25 cent value. If you cannot commit long term, like years and years long term, your diet plan is likely to not only fail, but have you gaining back all the weight you lost and then some. Been there, done that.
Just go with the LeanGains method (Berkhan). his protein reco is stupidly high (50-60% of daily macros?!?!) but it works. I value my kidneys at this point so I steer clear of that high.
