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.

Simple. Scientific. Sustainable.

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!

Serious about progress? You need this app.

For over 9 years, I tracked my calories using a basic, boring calorie tracking app. You know the deal... 1200 cals forever and an app that encourages you to “eat back” the calories it grossly overestimates you burned. Did I make progress? Yeah, some mediocre progress. However, since using Carbon Diet Coach, I’ve been dialing in on macro tracking. I look forward to the Coach’s smart recommendations each week. I am making incredible progress. Six pounds lost in five weeks, which is right on target with my goals. It’s very user friendly and I regularly watch Layne, Holly, and Keith’s videos on social media for additional tips. If you are serious about your health, you need this app. Let the Coach guide you. Like Layne says: “Trust the process, trust the work.” I am finally looking forward to a maintenance phase or even a building phase because now I have the tools to do so in a smart and planned manner. Also, Carbon’s customer service is fast and helpful. I made a mistake on one of my check-ins and a team member quickly and pleasantly assisted. At my request, they went into my account and helped me correct my check-in. My self-imposed issue was handled same day, no fuss. Absolutely incredible! Thank you to the entire Carbon team!

Best Fitness App on the market.

I’ve been using MyFitnessPal for years now and think it’s great however Carbon one upped it. Carbon essentially does what MFP does, tracks calories/macros but has a built in coach which adjusts your calories/macros weekly based on your goals. Whether you’re looking to lose weight, gain weight, maintain weight or reverse diet they have all of those options available. From a diet standpoint you can set it to balanced carbs, reduced carbs, low carbs, ketogenic even plant based. My biggest gripe is there is no option for a carnivore style approach which renders the built in coach useless if you’re following that style of diet. You can still enter in custom macros and use the app for tracking calories/macros. I’ve emailed back and forth between their customer service and they’ve always gotten back quickly with friendly and concise messages. On top of that there’s a very active Facebook group for app users. Even more impressive is Layne, Holly and Keith are very interactive in the Facebook group which in itself justifies the additional cost over an app like MFP. Overall if you’re looking for an app that will track your food and more importantly make suggestions to reach a goal you’d be hard pressed to find anything better on the market right now.
