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.
