The Roadmap To Success

Below Is What The Free Step-By-Step Weight Loss Course Entails. Once You Sign Up, You Will Have Access To This Forever.

My goal is to repair your mindset, extend your life at least 10 years, provide you the tools for you to lose fat and keep it off forever

You deserve the energy you desire to live life to its fullest. Remember, once you're gone, you're never coming back.


My name is Marc Giant, Registered Dietitian and Certified Nutrition Coach. I assist those that want to extend their lives for as long as possible and want to lose weight one final time via a sustainable approach. This Requires reversing psychological, emotional, physical and/or mental health as well as reversing the bad habits that have gotten you to where you are. You must want this as bad as your life depends on it, because it does.

I have been a Registered Dietitian since 2017, and have coached clients that have lost a substantial amount of weight and KEPT it off long term. How? Certainly not just giving out basic meal plans, but coaching the habits that are required to get you to where you want to be. Coming up with, modifying, practicing and tracking good habits is a necessity for losing weight at a healthy pace and keeping it off forever.

I practice what I preach. Why? I wouldn’t feel right if I told the clients I have worked with to do things that are outside their comfort zones while I sat back and didn’t veer outside my own comfort zone. I keep myself in the best shape I possibly can, mentally, emotionally, physically and psychologically. When I train at the gym, I make sure I train outside of my comfort zone to the point that I “want” to stop, but push forward regardless. By practicing mental strength, my physicality naturally follows (In other words, if you focus on being mentally resilient with your exercise as well as having discipline with your eating habits, a good, healthy body will naturally follow). 

I have run a lot of 5k’s, ½ marathons and the Detroit full marathon, but I have avoided, purposefully, things like competitions, simply because competitions often create an all or nothing mindset. You go all in when you compete, but then let go when you’re not competing, which puts you at a higher risk for being worse off in the long run. I am much more interested in simply competing with myself, every single day, so that I stay consistent long term. Questions I have been asked at the gym have varied from someone wanting to know If I was some sort of professional athlete, another person asked if I did indeed compete in weight lifting, and others have inquired on how I go so hard while exercising. I simply tell everyone the same thing, “I compete with myself”.

"Just hit my 90 days with 1on1 coaching with Marc, and I have to say this has been one of the best decisions I have made in my life!!! I have been on countless diets ( Atkins, Keto, Mediterranean, slim fast, subway lol), just to name a few, and none of them had consistent results. None of them were long-term solutions, and whatever weight I lost, I always gained back. Now that Marc has helped me make lifestyle changes, I have been losing weight at a healthy pace and hitting all my goals. I sleep better and have more energy ( I have a toddler, so I can use as much of that as possible). He actually listens to you and customizes everything for you. He keeps you on track , genuinely cares, and wants to see you succeed. I want to thank you brother and let you know how much I appreciate you. With your help, I'm going to continue to crush it in 2022!!!!"

Weight loss has been a struggle for me. All the yo yo dieting and teaching myself bad eating habits. Starving myself and closet eating so people dont see that I bing eat junk food has worn me out. Getting to your goal weight and maintaining it is a life long journey. I recently reconnected with some amazing cousins and one of them is a dietitian. Marc Giantt not only is he a cool dude he is also a great coach and has been helping me with my journey to get to my goal weight of 180 and teaching me a healthy way of life. If you are struggling with weight loss and yo yo Dieting and can't keep off the pounds you lose, I highly recommend giving this a try. Not only has Marc taught me healthy eating habits he has provided me with the tools to maintain my goal weight for the rest of my lif

"During my time in Marc's nutrition program, he helped me understand the importance of increased protein intake, helped me stay on track while I found my motivation. He takes time to answer all your questions and the weekly meetings help with accountability. I definitely recommend for anyone who needs that push to get on track"

"I had the opportunity to work with Marc Giant to help me get back in shape after my second total hip replacement. Marc explained the importance of eating the proper nutrients to help repair and build my physique. I had a goal to compete in a figure competition at the end of the year and Marc was a big part of my success in achieving that goal. We worked on the foods I consumed before and after training sessions plus my sleep and hydration methods. Marc knows his stuff! I am so glad I listened to his advice and knowledge of science about nutrition. I thank Marc for the transformation my body and mind went through and have continued to use what I learned to maintain a healthy body."

I wanted to take a minute to say how happy I am that I signed up for the weight loss course. It has not only given me the formula I need to lose weight but the tools to battle my triggers and how to find out what my deeper motivation is which keeps me on track mentally. I’m very excited about some of the foods I now get to enjoy again that I had been denying myself. Best investment I have made in myself in years!

I have come a long ways with my fear foods and eating habits since working with Dietitian, Marc Giant. I have an eating disorder which is complete hell to live with. And although weight restored, I am not fully in recovery but would be nowhere near close to recovery without Marc helping me tackle these fear foods!

Marc Giant is an amazing licensed Dietitian, and Health Coach, and he is so good at what he does, which is helping others reach their goals! I feel amazing, and am very healthy because of Marc , as he has taught me so much on my journey. I definitely would not have been able to build the muscle I now have, plus becoming a leaner me without him. It’s interesting to have a coach to put so much encouragement in your brain, and it really does stick after a while. He never let me fail!! Thank you Marc for making me realize health comes first, so I can enjoy life for a very long time!
