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.

Worth Its Weight In Gold

Aside from my camera and the Bible app, I am hard pressed to think of anything on my phone that has had a more significant impact on my life than Carbon. There just isn’t anything else like it. I’ve used Carbon for just over 9 months now, and in that time I spent 5 months losing the easiest 25 pounds I’ve ever lost followed by a month at my maintenance calories. The last 3 months have been using the reverse diet setting to slowly increase calories over time, improving the amount of food I can eat without gaining weight.

The expertise is there and the science behind Carbon is clear. There are no sketchy marketing smoke and mirrors. If you can stay complaint to the coach’s macros for you (protein, carbs, and fat) each day, you will achieve your goal, period.

If it seems intimidating, I assure you it’s easier than you think to use this app. If you need help, support has been outstanding the two times I’ve reached out to them with questions, and the three owners of the company conduct an open Q&A on social media every week. There are helpful instructional videos in the app, and a phenomenal (like actually helpful and encouraging) Facebook group of users of all ages and fitness levels who are there to help. I cannot recommend an app more highly. Carbon makes body composition changes just absolutely dead simple to understand and engineer. You will not be disappointed.

This app is incredible!!

I have struggled with weight my entire life. There is so much misleading information in the health and fitness industry and a lot of it led me to disordered eating, big weight fluctuations and feeling defeated. Several years ago I discovered Layne Norton online and his honest information is what I needed to really understand nutrition and to see through all of the lies in the industry. When I heard he was behind the Carbon Diet Coach app, I was really excited to try it. I have used the app for a month now and have seen better weight loss results than I have ever seen before. Not only are the results there, I’m not super hungry and grumpy like on other meal plans. It is super easy to use and the coach feature is just like a real coach telling me each week what my calories and macros need to be at to reach my goal. I love that it adjusts based on my results throughout the week so that it is always keeping me on track to hit my goals. I have already told a lot of people about this app and will continue to highly recommend it.

The cost of the app is negligible compared to the value it gives it’s users. I see myself being a long-term user of this app and feel more confident than I ever have that I will finally hit my health goal and maintain the results for the rest of my life. I’m very grateful I found this app and highly recommend it to anybody considering it.

Finally making progress!! ,

This app is off the charts AMAZING!

I’ve been waiting for Layne’s app since he was rudely and stupidly kicked out of “the app that shall not be named”. For the past few years I’ve struggled with 5 other apps (including the one not named above) and even hired a PT for a year because she also helped with macros. Yet I couldn’t make the scale move despite weighing and tracking because I was constantly running into road blocks in the food categories. I’d have to deconstruct whole meals in order to find certain items! It was the extremely time consuming and just horrible for my morale! Ultimately I gave up on all of them and bought FLF and Reverse Dieting (also brilliant books) and really tried to figure it out myself, but my inability to “math” was, well ... a problem. FINALLLLLY Carbon Diet Coach was born and SO worth the wait! The food catalog is the best I’ve seen! I have NOT had to deconstruct a meal and am happily shocked when I can find cultural foods or meals that I eat and have never found in any other app! THIS app was the missing link for me, HANDS DOWN THE BEST! I am 6lbs down in the first month and more motivated to log my meals than ever! Thank you Layne, Holly and Keith for creative something that is truly special and above all else, very well made! I’m so grateful for how responsive you all are with questions! Customer service is also above the rest! Top notch! Congrats!
