  • 48: 6 Ways to Stay Healthy While Seeking Weight Loss Goals (& Why Your Gut Microbiome Matters!)
    Mar 13 2026

    Trying to seek weight loss goals without sacrificing energy, your health and tanking your metabolism? In this episode, I’m sharing 6 practical tips to stay healthy while losing weight, and why your gut microbiome may play an important role in weight management and body composition!

    There’s a lot of conflicting advice online about weight loss. As a Registered Dietitian, I take a weight-neutral approach and focus on strategies that support long-term metabolic health, energy, and healthy body composition (muscle, fat ratios) rather than restriction or focus on numbers.

    YOU’LL TAKEAWAY:

    ✅ How protein and fibre intake can support appetite control, satiety, and healthy weight loss

    ✅ What the research says about the gut microbiome and its potential connection to weight

    ✅ How chrononutrition and eating in alignment with your circadian rhythm may impact metabolism

    ✅ Why focusing on body composition and visceral fat, rather than just the number on the scale, is key for long-term health
