About this app

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. Overate on one day and not sure what to do with your nutrition plan for the rest of the week? Adjust the diet planner to account for what you overate and Carbon does the rest!

Other coaching features include:

• Adjustable check-in days
• Check-in explanations so you're never left wondering why the app did or didn’t make a change
• Check-in history so you can look back and see why the app made various adjustments
• Charts showing your weight, body fat, lean body mass, calorie intake, protein intake, carbohydrate intake, fat intake, and metabolic rate
• Early check-in feature for those who can’t always check in on their specified day
• Goal tracker so you can see the progress you’ve made and how close you are to your goal
• Recommendations after you reach a goal so you can plan for what's next and KEEP your results

Already know what you are doing with nutrition and don’t need Carbon to coach you? No problem, you can enter your nutrition targets and simply use the food tracker. Beyond the amazing coaching features of this app is a food tracker that's excellent in its own right. Its features include:

• A huge food database
• Barcode scanner
• Quick add macros
• Copy meals
• Favorite foods
• Create custom foods
• Create custom recipes

No matter what your goal is, Carbon Diet Coach is your solution.

This macronutrient calculator is too simplistic and not worth the high monthly price of 10.99€. The app gives you a macronutrient target for the week. If you were compliant, it will then adjust it depending on your weight change. However, this adjustment is only performed if you were compliant. So you might be losing/gaining weight without targets adapting. I suggest to use freely available calculators or adaptive TDEE tracking spreadsheets. Also the food tracker did not recognize most food.

Love it. Easy to track macros and adjusts automatically macro goals when it needs to to get results. I wish it made fiber front and center along with calories, protein, etc. I have fiber goals, too. :) Oh, and please improve nutrition label scanner for two column labels, eg a can of soup lists nutrition info side by side for a serving and the whole can.

Thanks for the awesome 5-star review and for being a Carbon Diet Coach user! We’re glad to see you’re loving the tracking and automatic adjustments. Great call on highlighting fiber and improving the label scanner; we’ll share both with our team. Feedback like this helps us make Carbon even better!
