I am new to meal prepping. Former Army so I'm used to rigorous workouts and I am implementing calorie restriction in order to lose the excess pounds that I gained after retiring. I am currently using 40% protein, 40% carbs and 20% fat macros to lose weight and I have gone down from 265 to my current 249 lbs. I exercise about 45 minutes of lifting 3 times a week to help, mostly mild weight lifting in the HIIT style.
