## What is Carbon?

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
∙ Integrates with Apple Health to automatically read Body Weight and Body Fat values


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.

Simple. Scientific. Sustainable.

### 5/5 — Great

*2026-08-25, version 2.77.6010*

I have been using this app for 4 months and and I am down so far 12 pounds, but yo be fair I did go on a one month vacation where I added 6 pound. Three weeks after I returned I am back where I stopped before the vacation.

### 5/5 — Top of the line

*2026-08-21, version 2.77.6010*

Far superior to any app I’ve used, easy conversions based your preferred measurement (ounces, grams, etc.). Algorithm will adjust your calories +\- based on your scale results, easy to copy meals across multiple days at once if you meal prep… The app keeps getting better!

### 5/5 — Great for being honest with myself

*2026-08-20, version 2.77.6010*

I’ve used a few other macro trackers and I greatly appreciate that this one calls me out when I’m not compliant. Not only does this keep me consistent with eating habits, but also the weigh-ins. It is completely based on the data you enter. No data, no adjustments and likely less progress. I also really like the option of reverse dieting. They recently changed the one thing I didn’t like: I want to be able to copy previous meals since I meal prep. They made this easier to log, so looking forward to that feature.

### 5/5 — Great App

*2026-08-18, version 2.77.6010*

I have been using this for 2 years and it’s great. It’s is really easy to track everything and the interface is very user friendly. The chat support is great as well and I always get responses very quickly. The feedback given is clear and the adjustments are explained well. Overall great app if you’re looking to cut, bulk, or maintain.

### 5/5 — Trust is the utmost!

*2026-08-16, version 2.77.6010*

I trust the trends and base my future physical self on it!

### 5/5 — The best coach and tracking app

*2026-08-14, version 2.76.5966*

Look no further. It’s worth every cent. At last you don’t have to worry if you’re doing it right—carbon and the incredible team behind it has got your back. 

If you actually measure and log everything you eat and hit your target macros for 3 months, you’ll see so much progress. 

The app adjusts to your actual progress and adherence. I find it’s coaching to be accurate, not generic. 

I’ve recommended this to about 5 or 6 people who have started using it—each to great success.

### 5/5 — My coach

*2026-08-10, version 2.77.6010*

Coach was really good, but it updated and now it’s PERFECT.

### 5/5 — Best app for tracking macros

*2026-08-09, version 2.76.5966*

Great recipe builder and easy to adjust everything!

### 5/5 — Life changing

*2026-08-09, version 2.76.5966*

Lifted for years without adding muscle, using Carbon accomplished the goal.  Best support experience of any product in my entire life.

### 5/5 — The driver of my diet consistency

*2026-08-09*

I’ve struggled with maintaining and manipulating my body composition for most of my life until I started using carbon.
The app is easy to use, and I just track everything I eat even if I go over my calorie budget, because I can trust I can try harder next week and the AI will take care of me.

Just get the app and stop overthinking it.

**Developer response:** We absolutely love the way you described this. Progress gets a lot easier when one imperfect day stops feeling like a reason to throw the whole week away. Carbon is built to help you look at the bigger picture, stay consistent, and keep moving forward instead of chasing perfection. It’s great to hear that approach has changed how you manage your nutrition and body composition. Thank you for such a thoughtful review and for encouraging others to stop overthinking it!
