I used the following diet to cut to 4%, it's hard to stay on at first but a few days in and it's a breeze.
Breakfast: scoop of bcaa's, 3-5 egg omlet, with variation of veggie stir fry/salmon omlet/chicken
Snack: carrots/nuts/chicken in can/tuna/ try to stick with whole foods
Preworkout: simple carbs, fruits work best. Or Greek yogurt
Post workout: protein shake followed by another fruit or Greek yogurt
(Hour later): None gluten complex carb source (try keeping it under 30g's), whole protein source, and some fat such as cooking in olive oil, or salmon, flaxseeds.
Before bed ZMK is great before bed to recover quicker.
Eat what your body tells you to eat don't over eat or you'll put on body fat or under eat trying to cut. You'll just be loosing muscle. Good luck with the comp cut!!
