1,800 Calories Leap Of Faith

I'm doing Les Mills Combat and the nutrition guide states that I should be taking in 1,800 calories a day. YIKES! Not going to lie that many calories is scary! But I'm going to take a leap of faith, do it, and see what happens. I'll keep the macros 40-30-30 as close to that as I possibly can each day.

Here's go nothing!
