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.

I had a pretty good experience with Carbon early on, but over the last month the app has gotten a little screwy. Weird calorie and macro fluctuations. Also, I accidentally mistyped my weight on a check in and it threw all my macro recommendations in a tailspin. I was able to edit the weight I, but it didn't adjust the calorie or macro changes that had been done. It was like one typo wiped out over a year of data and energy calculations on Carbon. Hugely disappointing and frustrating.

Overall the app does two things very well and one thing is fairly confusing: 1) amazing interface and visibility for overall goals and progress, daily goals and progress and even showing macros by the meal is fantastic. 2) forcing protein/lb bw (and letting carb/fat be the adjusted slider) is very conducive to weight loss The Downside) The check-ins make no sense to me. It can clearly see when I miss or hit all of my macro or caloric goals, yet it still sometimes makes wild (or no) changes

The changes that the app makes are based on your weight trend! We use a multi-week rolling average of your weight to make adjustments. If you contact we are always happy to further explain why adjustments have or have not been made by the coach!

This is app is great! It's not a tracker, it's a coach. It helps take the guess work out of macro and calorie counting while also allowing some flexibility. The best thing about this app besides the coach, is the fact that you're able to add your own custom foods and meals into the app but they don't get entered into the main database. This means that other user's food entries will not appear when I search for a food, which makes the database less cluttered and more accurate. 100% worth the $$$!
