Carbon Diet Coach is your nutrition solution for results that LAST. Whether your goal is to lose fat, build muscle, improve your metabolism, or simply maintain your weight, Carbon Diet Coach removes the guesswork. Carbon Diet Coach is a science-based nutrition app designed by renowned nutrition coaches Dr. Layne Norton (Ph.D. Nutritional Sciences) and Registered Dietitian Keith Kraker (BS Dietetics). It does everything a normal nutrition coach would but at a fraction of the cost. Simply select your goal, answer a few short questions, and it does the rest! You will get a customized nutrition plan based on YOUR goals and metabolism. What's more, Carbon will adjust the plan as you progress to optimize your results. If you hit a plateau or stall, Carbon will make adjustments to keep you progressing towards your goal, just like any good coach would. Our coaching system uses the latest techniques in nutrition science to make sure you get the best results possible. All you need to do is follow these simple steps: ∙ Log your food using the built-in food tracker ∙ Log your body weight ∙ Check-in each week Do that and Carbon does the rest! Carbon Diet Coach can do things other nutrition coaching apps can’t do. For example, your nutrition plan can be tailored to your diet preference: ∙ Balanced ∙ Low Carb ∙ Low Fat ∙ Ketogenic ∙ Plant-Based Each setting is completely customizable so that you receive a plan that is sustainable for YOU! Another feature that makes Carbon unique is the diet planner. Want high and low-calorie days rather than eating the same foods every day? Use the diet planner to set up your week and stay on track.
