I would ask the experts here, but would consider adding one shake and/or drinking a Plazma before. I know Plazma is for lifting and pumps and blah blah, but the macros work with the diet, they suggest adding it on the V-burn day (probably a similar amount of calories burned vs. an hour skate) if you need the energy, etc… People have made this thing work with different types of programs, so it’s quite doable.
Assuming you’re skating at night, I might go: HSM a couple hours before, Plazma / some sort of extra calorie sourc eon your way to the rink (~200 cals), and nighttime shake right after (maybe add a scoop if you’re starving or find energy levels extra depleted the next day).
Net would be 200-300 extra calories, would be nicely surrounded so you have energy during, and even though you’re still burning more than you take in, that’s 1) the point and 2) not much different than you would have gotten in the NEPA.
I played some tennis as my NEPA a few days, which is definitely more like hockey in terms of energy usage, and I didn’t add calories, but I felt it a little bit.
