From Overweight Doc to Svelte Low Carb MD Changing Patient’s Lives: 27

Cheryl McColgan
NASM-CPT, E-RYT 500, BS Psychology and Graduate Training in Clinical Psychology

Dr. Brian Lenzkes was an overweight, stressed out physician who was frustrated with his inability to truly help his patients. After years of traditional practice within the US healthcare system,  he was overworked and frustrated. He eventually stumbled across low carb eating and Dr. Jason Fung who is a world expert on helping people with diabetes reverse their disease through fasting.

Once he transformed his own health through these practices, he knew he had to share these treatments with his patients. He proceeded to completely transform is practice and now helps his patients through a direct care model in which he is taking people off of medication daily because they are improving their metabolic health.

I am so excited to share his work with you! He is truly impacting health and wellness on a daily basis in both his life and the lives of his patients.

    Read more about Cheryl and the journey that created Heal Nourish Grow on the about page.

    Cheryl McColgan is the founder of Heal Nourish Grow, where she writes about protein, body composition, healthy aging, and evidence-based nutrition and wellness along with the everyday habits that actually make those things work in real life.

    With a background in psychology and graduate training in clinical psychology, plus nearly 20 years of experience in editorial and publishing, Cheryl approaches health from both a research and real-world perspective. She’s also been immersed in fitness and nutrition for more than 25 years, which gives her a practical lens most purely academic content tends to miss.

    Her work today focuses heavily on protein intake (especially for women), muscle retention, metabolic health, and sustainable fat loss, along with topics like sleep, wellness, recovery, and wearable health tech. You’ll also find a mix of high-protein, low-carb recipes designed to make hitting those goals easier without overcomplicating things.

    Cheryl’s interest in health and nutrition became more personal after navigating her own health challenges, which pushed her to dig deeper into how lifestyle, diet and daily habits impact long-term health. That experience continues to shape how she approaches everything on this site: practical, realistic, and focused on what actually works over time.
    What Cheryl Covers
    Most of the content here falls into a few core areas:

    Protein & Muscle Health: how much you actually need, especially for women and how to use protein to support strength, body composition, and aging
    Fat Loss & Metabolic Health: sustainable approaches that prioritize muscle retention and long-term results
    Healthy Habits & Lifestyle: sleep, movement, strength training, consistency, and the small things that compound over time
    Wearables & Recovery: real-world testing and comparisons of tools like Oura, Whoop and others
    High-Protein & Low-Carb Recipes: simple, realistic meals that support your goals without feeling restrictive
    Travel & Lifestyle: wellness-focused travel, outdoor experiences, and a slightly more elevated take on healthy living
