About this app

Carbon Diet Coach is your 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), Holly Baxter (MS Dietetics), 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.

Want to love but I eat a wide variety of foods and had a hard time finding most in the database. I've added the majority of the foods myself and need to separately look up ingredients on packages or Google to create them. Seems less comprehensive than MyFitnessPal for a lot of "international" foods, takeout meals, and prepackaged foods I typically eat or use. For example, I couldn't find the nutrition profile for the beef plate, and what existed didn't specify grams per serving.

I like the diet coach function in this app. But I was going to cancel it because I was using my fitness pal for food tracking and worked so much better. When I found out that this app also had a barcode scanner I did not renew my fitness pal and switch my diary over to here. The problem is the barcode scanner has not recognized a single food so this is turning out to be way more work than I thought it would be. Ugh. Back to MyFitnessPal...

pretty good, I like the idea of having dynamic calorie and macro targets to "dial in" the nutrition. Also, tracking macros and calories is a great idea and this seems to be one of the best at doing it. I think a more robust/intuitive way of setting your initial goal/targets is needed. E.g., some small changes in how you answer the questions leads to drastic differences in the recommendations.
