Why Choose Nutrition by Ruth

Taking a GLP-1 medication for weight loss or diabetes management?

If you're taking or considering GLP-1 medications like Ozempic, Wegovy, Mounjaro, or Zepbound, proper nutrition support is essential for maximizing results while protecting your health. While these medications are powerful tools for weight loss and blood sugar management, they come with unique challenges: rapid muscle loss, nutrient deficiencies, digestive side effects, and the critical question of how to maintain your results long-term. As a Registered Dietitian with decades of metabolic health expertise, I help clients on GLP-1s optimize their nutrition to preserve lean muscle mass, prevent nutritional deficiencies, manage side effects, and build sustainable eating habits that last beyond medication. Whether you're just starting, currently taking, or transitioning off GLP-1 therapy, I provide the evidence-based guidance you need to achieve lasting health—not just temporary weight loss.

Taking Ozempic, Wegovy, or Mounjaro? You Need Nutrition Support.

GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound have revolutionized weight loss and blood sugar management—but they're most effective when paired with expert nutritional guidance. If you're currently taking these medications, considering starting them, or planning your transition off, specialized nutrition support isn't optional—it's essential for protecting your health and ensuring lasting results.

The Hidden Risks Your Doctor May Not Have Mentioned

While GLP-1 medications deliver impressive weight loss, they come with critical nutritional challenges: rapid muscle loss (up to 40% of weight lost can be muscle, not fat), severe nutritional deficiencies from drastically reduced food intake, difficult side effects like nausea and food aversions, and the biggest question of all—what happens when you stop? Without proper nutrition support, many people regain the weight and lose the muscle they worked so hard to build.

Evidence-Based Nutrition for GLP-1 Success

As a Registered Dietitian specializing in metabolic health, I provide personalized nutrition protocols that work alongside your GLP-1 medication. We'll optimize your protein intake to preserve lean muscle mass, prevent nutritional deficiencies through strategic meal planning and supplementation, manage side effects with foods that work for your reduced appetite, and most importantly—build sustainable eating habits that ensure your results last long after you stop the medication. This is about maximizing benefits while minimizing risks.

Lose Fat, Keep Muscle, Build Habits That Last

My clients on GLP-1 therapy don't just see the number on the scale drop—they preserve their muscle mass, maintain their energy and strength, avoid the nutritional deficiencies that plague many GLP-1 users, manage side effects effectively, and develop the eating patterns needed to maintain their results for life. Whether you're on these medications for 6 months or 2 years, you'll have the nutritional foundation to thrive during and after treatment. This isn't temporary weight loss—it's sustainable transformation.

What Our Clients Say

Testimonials

Best Registered Dietitian in San Diego for Gut Health and IBS Relief
After struggling with IBS, chronic bloating, and digestive issues for over 6 years, I finally found relief working with Ruth. As a registered dietitian in San Diego with decades of experience, she took the time to understand my gut health challenges and created a personalized meal plan that actually worked. Her online gut health course was incredibly informative—I learned more about the gut microbiome and anti-inflammatory foods in 12 weeks than I did from years of googling. Within just 3 weeks of following her evidence-based nutrition protocols, my bloating decreased by 80%, I had regular bowel movements for the first time in years, and my energy levels completely transformed. Ruth doesn't do fad diets or quick fixes—she focuses on sustainable, science-backed approaches to healing your digestive system. If you're in San Diego or anywhere looking for virtual nutrition counseling for gut issues, Ruth is absolutely the best. Her combination of clinical expertise and genuine care for her clients is unmatched. I've now lost 18 pounds (as a bonus!), my skin cleared up, and I finally feel like myself again. Highly recommend her gut health programs to anyone dealing with IBS, SIBO, or food sensitivities!
