Our food tracking system is focused on creating a way for users to hit their daily nutrition targets consistency using a unique tracking method for each macronutrient category. In our experience, consistency is the key to changing your body and without a reliable, easy tracking system, many people fall short of creating metabolic adaptation and never reach their goals. The app removes the stress of precise performance that other apps demand. Instead, our system creates a scenario in which you are performing within a caloric range of where you need to be for your body to seek fat loss, muscle gain or improved energy, sleep, digestion, and athletic performance.

The app will also track bio-feedback on sleep, energy, exercise and stress relief. These factors play a critical role in helping your body change effectively, so understanding your performance in these categories helps create consistency and awareness on where to improve. Calculating Your Daily Intake: Our app will calculate your resting metabolic rate in order to accurately calculate your daily calorie needs for your goals. When selecting your goal, you have 3 goal criteria to choose from: • Fat Loss • Muscle Gain • Maintenance A 4th option “Custom” will allow you to manually enter your daily calorie target as well if you choose not to select from the 3 preset goals. Once you select your goal, you will have one more option to select from, your macronutrient composition.
