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!

Blown away by how good this app is!

I’ve been a chronic dieter for years. I’ve used so so many apps for tracking. Usually when you get a new app, it takes so long to get comfortable using it and adding all your food to easily input it. Let me say this is the most user friendly dieting app I’ve ever used. First off the coaching side of it is way more spot on than any other guesstimate calorie/ macro estimate I’ve ever gotten. They ask a lot of questions to get you right where you need to be. You can input your weight daily on the app and it averages it out over the week which is so cool! You can add up to 7 customizable meals. The search data base must have taken them so long to input! It’s all verified foods with REAL calorie and macro breakdowns (unlike MyFitnessPal which will have a cheeseburger at 10 cals sometimes because users are inputting.. very inaccurate). I looked up a beer.. it had info for countless beers! Wine, countless different grape varieties... a taquito.. it was on there. Makes tracking so simple and easier than ever while being ACCURATE:) it’s so many apps all in one! I couldn’t be more excited about finally
Having an easier way to track! Thanks layne norton and team for putting this together!

Next level app! Simply the best!

I have tracked calories and macronutrient for years and this is by far the best app on the market.I was absolutely blown away with the ease of the carbon app especially after being so comfortable with tracking on other apps. The daily and weekly macro tracking goals make it easy to see your targets and it is so fast to upload food. I was even more impressed with the food search, the carbon app has one of the best databases I have come across and again did I said this app is so FAST. Being a long time macro tracker, bikini athlete, coach, student, business owner and mom I was a bit hesitant to starting a new tracking app and switching all my favorite foods. I worried I wouldn’t have the time to get it all together in one day and still do my life, but the ease of the carbon coach made it easy and seamless. I even found a long time favorite food of mine that was tracked wrong in the other apps. I highly recommend you download the carbon app today for some accurate counts and serious motivation.
