“Nick is fantastic! I’ve struggled with my weight and relationship with food my entire life. He’s been helping me change my habits and how it fits into my life and is helping make my weight loss more sustainable than the yo yo effect I’ve been having for years. He is also giving me tips and recommendations in how to incorporate more movement into my life since my job is relatively sedentary and takes up such a large part of my waking time. He is always very open and understanding during the appointments and makes sure to cover all of our goals during each appointment. ”

“Nick spent over an hour and a half with me on our first call. He took the time to not only understand my eating habits but also my personality so he could help create a plan that works for me and my personality. I look forward to working with him more.”

Nick has helped me get into the best shape of my life while still fitting it into my lifestyle. Not only is he an amazing coach, he is positive, motivating, and there for you during the ups & downs your journey will have for you. He has also helped my dad Recover after open heart surgery and get a better hold of his diet & health. I would 1000/10 recommend him

I’m so glad I reconnected with Nick recently — I honestly didn’t expect the level of support and motivation he gave me. I’d been wanting to make healthier changes, and he really took the time to understand my goals and lifestyle before creating a nutrition plan that actually fit into my day-to-day life.
Nick is super knowledgeable and straightforward (which I love), but also really encouraging and easy to talk to. I never felt judged or pressured — just supported and understood. He was always quick to answer questions, explain things clearly, and make adjustments when needed.
Even though I didn’t stick with it perfectly, I learned so much from him about nutrition, balance, and building better habits. If you’re looking for someone who’s professional, passionate, and truly cares about helping people reach their goals, I can’t recommend Nick enough

Nick has been a game changer for me. He has been super patient with me by creating small, achievable goals for me and educating me on behaviors and norms that weren’t nutritionally sound. When I am hard on myself for missing a goal or not getting it 100%, Nick has been there to find the good & help me focus on what’s next. I really appreciate how Nick listens and doesn’t just stereotype your medical issues into an impossible diet change. He is realistic and focuses on your whole self. Super grateful to have Nick as a resource & partner.

In our most recent session, we talked about how I was really only prepping for two meals a day and struggling to stay consistent with lunch — especially since I’m a hairstylist and need something fast and easy between clients.
Nick suggested I try prepping wraps as a quick, balanced option, and it’s honestly been a game-changer. I’ve been so much more consistent with eating three meals a day, and my snack choices have improved too. He’s given me so many simple, realistic tools that actually fit into my lifestyle.
He’s also super nice, down to earth, and easy to talk to, which makes the whole process feel approachable and motivating. I’m genuinely excited to keep learning and prepping each week!

Nick was always courteous and truly concerned about how I was doing and motivating me always to be my best. After each session I was more motivated than ever to attaining my goal.

I cannot say enough good things about Nick. He listens to me and takes the time to understand my unique needs, challenges, and goals. From the very beginning, he met me where I was in my health journey… no judgment, just genuine care and guidance.
Rather than pushing fad diets or quick fixes, he focuses on building the right foundation for lasting success. He helped me not only lose weight but also provided the tools and knowledge I need to keep it off. His approach emphasizes steady, sustainable progress and helps create a healthy relationship with food that actually lasts.
Thanks to his support, I’ve built habits I can maintain for life and finally feel confident that the changes I’ve made are here to stay. If you’re looking for someone who truly listens, understands, and helps you achieve real, long-term results, I highly recommend Nick Mosakowski.

Nick truly listens and takes the time to understand my overall health, not just my diet. He asks thoughtful questions and really tries to get to the root of what’s going on, rather than offering one-size-fits-all advice. I appreciate how he looks at the full picture — physical, mental, and lifestyle factors — to guide his recommendations.

I came to Nick because my family has a history of heart disease and high cholesterol and I wanted to get out in front of it. Nick helped make me aware of some bad eating habits and made some heart and cholesterol friendly modifications to my diet. He also provided some recommendations on the easiest ways to help implement these changes without getting discouraged!
Nick also helped me develop a training regimen for my 100 mile bike ride which I crushed thanks to him. I've never gone into a race more prepared and it showed.
Highly recommend!
