1. 5/5Incredible App

   I’ve struggled the last few years with trying to lose weight and get in shape. I’ve tried countless plans and programs only to stick with them for a couple weeks, not see instant progress, and then give up. I’d read something about this or that system and think, “Aha! This is what will finally work!” I was making things way too complicated and not taking a good, honest look at my lifestyle. I was blaming all these plans for me not succeeding. I was blaming my slow metabolism or my hormones. I read about Carbon on Instagram and decided to give it a try. Something clicked. I don’t know if it is because Carbon is pretty simple and straightforward and therefore doesn’t cloud my brain with all kinds of crazy misinformation. I don’t know if it is because it really makes you aware that your success or failure is in your own hands, nobody else’s. I don’t know if it is because it gives you the flexibility to stick with it while still allowing you to enjoy food that you love. Whatever it is, it has kept me moving in the right direction for six weeks, which is the longest I’ve stuck with something in a long time. Carbon tells you what to do but doesn’t do the hard work for you. There’s no magic pill or fast track to reaching your goals. You still have to flex that willpower muscle. Sometimes it’s really challenging and sometimes you may not be happy about the changes that Carbon makes to your macros. But as long as you trust the process and appreciate that slow and steady wins the race, Carbon will absolutely help you reach your goals.

2. 5/5This 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.

3. 4/5Good, but wish it had more

   This is a good tool- it is just a tool though. I noticed it was setting my calories too low after my first week and I hadn’t dropped weight, which is fine because it was literally my first week tracking officially. It was around the time before my period, so weight gain and water weight is expected. I wish it took into account or had the option to track cycles (I didn’t see anything that had that). I ended up overriding it every time and setting my calories and macros to what I know is a deficit. I also have noticed some clothes are fitting looser than before, but the scale is the same. Data-wise Carbon looks at weight only, which is why I manually adjusted it. When I start seeing progress on the scale, I’ll let Carbon dictate my macros. For now, I have to override everything. I also add 100 calories or so when it’s my time of the month. If you know your calories are too low, adjust them. Carbon is a tool and it’s going off of your weigh ins- it doesn’t take into account the multitude of factors that can occur and that’s okay. It’s just an app, it’s not magic- so I would never expect it to do that. It’s a good app, pretty easy to log. A little hard to log when it’s a recipe with multiple components. I like the check ins and that it does hold you accountable. I am not always consistent with my macros and calories but I’m getting the hang of it after a few weeks. It would also be nice if it had a recipe section (I know it has recipes you can add, but like actual recipes would be cool)

4. 5/5This 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!

5. 5/5This app changed me

   This app has changed the way I eat, how I look at food, helped me lose 12 lbs in 9 weeks (I am still going strong), and just overall lifestyle. I have fell victim to so many BB diets before (carb cycling, keto, chicken and rice, blah blah blah) and to be honest I was skeptical and totally thought my body couldn’t handle carbs. I thought if I ate a decent amount of carbs that I would gain weight and fat. I went all in after a spinal fusion surgery as I knew I had to change how I was living. This app has shown me food is not an enemy, and has allowed me flexibility ‘dieting’ while still enjoying foods I love like Wendy’s, ice cream etc. I’ve spent years talking about getting shredded and losing weight and pretty much being an idiot, but this app has been the only thing that has worked and it’s because it’s changed my mental relationship with food. If I don’t hit my numbers now, meh, so what, the next day I’m back on track and this app accounts for it and life happening! I’m telling you, I was skeptical but a firm believer in this app, because I’ve seen the change it has helped me achieve and the cool part is I’m only 9 weeks into using this. I’ll be using good for a very very very long time! Don’t wait, just jump in, learn, and make your progress you’re wanting! Thanks to Carbon Team!
