We've made meal prep an easy, effective solution for anyone! Here's the facts: 80% of diet results come from macro-nutrients and total calories. Real science shows a total caloric deficit is what's necessary for sustained fat loss (as opposed to diets or food choices). Meal prepping helps you easily control the amount of calories and macro nutrients you eat and gives you complete control over your body composition whether that be fat loss, muscle gain, or both! Take the first step. Fitpacker wants you to take back control! Control your portions and count your macros! Meal prep is one of the best ways to help you achieve your goals!
