Turn ChatGPT Into Your Personal Meal Planner

Even for someone who lives and breathes nutrition, meal planning can feel like a grind. There are weeks when I sit down to plan our family dinners and feel like I’m reinventing the wheel. I want meals that are nutrient-dense, aligned with our dietary framework, seasonally appropriate, and ideally not the same five dishes we had last week. That’s a tall order. Lately, I’ve found a solution that has completely transformed this process: ChatGPT. This article will show you exactly how I use ChatGPT as a meal planning assistant, and how you can create your own personalized version with a simple, copy-paste prompt.

Quality Matters: How to Choose and Use the Best Collagen Supplement

Introduction If you’ve been paying attention to health and wellness trends, you’ve likely noticed collagen supplements everywhere—from your local health food store to your Instagram feed. It’s not just hype; the collagen market has grown to a nearly $3 billion global industry, and for good reason. Collagen is the most abundant protein in our bodies—it’s quite literally the stuff that holds us together. The word “collagen” comes from the Greek word “kólla” meaning glue, which perfectly describes its function as the structural framework for our skin, bones, tendons, and connective tissues. Our ancestors naturally consumed collagen-rich parts of animals—skin, tendons, and bone broths—as part of their nose-to-tail eating approach. Modern diets focused primarily on muscle meats have created a collagen gap that supplements can help address. This represents...

Collagen: The Essential Building Block for Strong Joints and Bones

The Foundation of Your Musculoskeletal System If you’ve ever winced going down stairs, felt that telltale morning stiffness, or worried about thinning bones, you’re likely experiencing what I see in my practice every day – the effects of declining collagen. I often tell my patients that collagen is literally the “glue” that holds us together – in fact, the word “collagen” comes from the Greek word “kólla” meaning glue. It’s the most abundant protein in your body, accounting for about 30% of your total protein content, and it’s absolutely crucial for maintaining the integrity of your joints, bones, and connective tissues. Think of collagen as the structural framework of your body – like the support beams in a house. Without enough of it, things start to sag,...

Collagen for Natural Beauty: The Science Behind Healthier Skin, Hair, and Nails

That first moment you notice deepening lines around your eyes or suddenly realize your nails have become brittle and prone to breaking—these experiences often signal the same underlying issue: diminishing collagen. As we age, our bodies naturally produce less of this critical protein, but research shows that targeted supplementation can effectively restore many of those visible signs of youth. What Is Collagen and Why It Matters for Natural Beauty Collagen isn’t just any protein—it’s the most abundant protein in the human body, making up about 75-80% of your skin’s dry weight. [1] The word “collagen” comes from the Greek word “kólla,” meaning glue, which perfectly describes its function as the structural scaffolding that gives our skin its firmness and elasticity. [2] Our natural collagen production begins declining in...

Bacillus coagulans: A Versatile and Safe Probiotic for Gut Health and Beyond

If you’ve been following the latest developments in gut health research, you’ve likely encountered Bacillus coagulans. This unique probiotic has been gaining attention in the functional medicine community, and for good reason—the research supporting its benefits is already robust and continues to grow. As someone who’s worked with thousands of patients with gut issues, I’ve found that probiotics can sometimes be a double-edged sword. They offer tremendous benefits for many, but for others—particularly those with sensitive digestive systems—they can sometimes trigger discomfort. This is where B. coagulans offers a distinct advantage. What Is Bacillus coagulans? Bacillus coagulans is a spore-forming probiotic bacterium that stands apart from many of the more familiar lactic acid bacteria like Lactobacillus and Bifidobacterium. Its spore-forming ability gives it a remarkable resilience that most...

Why Bacillus coagulans Is My Go-To Probiotic for IBS and SIBO

If you’re struggling with irritable bowel syndrome (IBS) or small intestinal bacterial overgrowth (SIBO), you know how challenging these conditions can be to treat. The complex web of symptoms—abdominal pain, bloating, irregular bowel movements, and more—can significantly impact your quality of life. Studies show that IBS affects up to 15% of the global population, making it one of the most common gastrointestinal disorders worldwide [1]. When I first started my practice, I prescribed standard probiotics to my patients with IBS and SIBO, just like most clinicians. But I noticed something concerning: these patients not only didn’t improve—they often got worse. This observation sent me down a path of extensive research and clinical trial and error, ultimately leading me to discover that Bacillus coagulans was consistently the...
