### 5/5 — Great system

*2026-04-22*

I’ve been using his methods for a couple of years now. When I first started, I followed the Metabolic Build as recommended, and it got my intake up to a little over 4,500 calories per day. That’s significantly higher than what traditional online calculators suggest for my size (usually around 3,100 for maintenance), but I was essentially recomping while doing it.

Overall, it’s a great program if you’re serious about your nutrition. It’s also very easy to input your data and follow consistently.

One issue I’ve run into is communication. I no longer use social media, and from what I’ve found, there’s no way to get in touch with them outside of Instagram or TikTok. But as a side note, when I did have social media, he was very responsive and respectful. 

Right now, I’m dealing with a problem in the app related to the macro profile and calorie settings that I haven’t been able to fix. For example, my weekly totals show fat at 4,914, carbs at 16,582, and protein at 4, which obviously doesn’t make sense. When I check the “How Am I Doing” section in the food tracker, the numbers look different (and seem correct), but everything is still showing in red—even though I’ve logged my food for the day.

I’m assuming it’s just a glitch. It’s definitely frustrating, but it doesn’t take away from the effectiveness of his methods. Like anything else, technology has its flaws.

### 1/5 — Macro coach is good, food tracker not so much

*2025-10-02*

Macro coach is great although calories have hardly been adjusted in the time I’ve been using it week to week

My biggest complaint is the food tracker and how it constantly makes you log back in and errors out more time than not. It’s always saying no response from server and then you try again and it’s the same and then you log out log back in and have multiple entries food tracker definitely need some debugging.

Matt is knowledgeable but don’t fall for the I’m almost full urgency sales tactics for 1 on 1 clients

### 5/5 — 1:1 coaching

*2025-09-17*

I used the macrocoach for about 6 months and made great progress but I still had some problems working my diet and nutrition out. I signed up for 1 on 1 coaching and stayed on for 2 years. It was well worth the knowledge and expertise provided to me. Working with fitdisel was a great experience, he tailors the program to your needs and understands life happens and helps you work through it. Very responsive to any questions and always has the answers! It has increased my confidence to continue to make progress in my fitness journey and live a healthy lifestyle.

### 5/5 — Fit Diesel is for real!

*2025-05-06*

I started 1/1/23. 223 lbs. currently 185 and have hit 183. The method is fantastic- it works- all you have to do is do the work. Week by week progress will show up if you follow the Macro Coach!!

### 5/5 — Trusted by Healthcare Professionals

*2024-12-04*

Dedicate time to researching the development of the app’s nutritional and fitness features. The science behind both will help you reach your goals.

### 2/5 — Macro coach is great, good tracker not so much

### 5/5 — Science Based “Dieting”

*2024-09-18*

MacroCoach has helped me reach goals I didn’t think possible! I am down 20 pounds and increased my metabolism to 2200 calories/day! I am 27 and have tried intermittent fasting, intense workout with carb deficits, and whole30. Nothing has worked but FitDiesel follows the science!

### 5/5 — The best lifestyle change I’ve ever made!

*2024-09-03*

Very grateful and a big thank you to this program! I started using fit diesel after my daughter was born. I was having a hard time losing the weight and just felt bad about myself. Now, For the first time as an adult I have a healthy relationship with food. I didn't realize how bad all those trend diets were for your physical and mental health. I plan on using the program through my current pregnancy and after as well! This program really works! It’s not a diet, it’s truly a lifestyle change that makes feeling and being healthy achievable!

### 5/5 — This app is a game changer!

*2024-06-28*

I've tried Macrofactor, my fitnesspal, and a couple of other apps. Lots of similarities between those apps, but Fit Diesel takes it to another level, and has been a life changer. I'm not a big technology guy, but this app is by far the most user friendly compared to the others. Its simple to use, and it takes the all guess work out of nutrition and dieting. You supply the data, the app does the rest for you, and its. There's tons of explainer videos, so there's never any guessing or any confusion. Tacking calories, macros, and other data used to be a chore and very time consuming. This functionality built into this app turns what used to be a time consuming chore, and makes it something that is quick and easy. 
 
As far as how the app works, its much more geared to the individual than the other apps. It takes into consideration much more data, such as tracking steps and weekly activity, weekly compliance, as well as other external factors to determine your adjusted calories and macros for the next week. I know for females it takes even more information into account as well. The science and math with this app are spot on. Lastly the goal feature is more expanded than the other apps, which allows you to tailor it more specifically to what you want. Its not as simple as gain, lose, or maintain weight. Programs to identify and build your metabolism, and lean muscle build are 2 that the others don't offer that i absolutely love. And they're always working to improve it and make it better. The newly added charts to helps numerous past data points is by far my favorite. Highly recommend this app to anyone who wants to get fit, get healthy, and do it eating the foods they want. Love Fit Diesel, wish i would have known about it years ago!

### 5/5 — Just do it for yourself, it works!

*2024-06-26*

I'm so happy I signed up for Fit Diesel's program. I've been on the metabolic build for almost 2 months now and I've never felt better. I'm down just about 15 pounds. I'm 51, peri menopausal, had a thyroidectomy and gained 30 pounds in a little over a year. I didn't think anything was going to work. THIS WORKS! I'm excited to start the weight loss program in a couple of weeks. Thank you again!
