The Truth About Your Metabolism (Part 1): Age, Muscle & Calorie Burn

from Beyond Fat Loss · host Katie & Sean Darlow

Does your metabolism really slow down as you get older—or is that one of the biggest myths in health and fitness?In Part 1 of our two-part metabolism series, we dive into the science behind metabolism, ageing, muscle mass and calorie burn to separate fact from fiction.Using one of the largest studies ever conducted on human energy expenditure, alongside the latest evidence, we explain why age itself isn't the primary reason many people struggle to maintain their weight as they get older. Instead, we explore the lifestyle and body composition changes that have the greatest impact on your metabolism - and, more importantly, the factors you can control.In this episode, we discuss:• The difference between BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure)• Why muscle mass plays a key role in maintaining a healthy metabolism• Whether your metabolism actually slows down between the ages of 30 and 60• Why physical activity often declines with age - and how that affects calorie burn• How maintaining muscle supports long-term health, strength and independence• The research behind metabolism, ageing and energy expenditure• Practical strategies to help you stay active, build muscle and support your health for decades to comeThis episode is designed to empower you with evidence-based information so you can focus on the habits that truly make a difference, rather than believing you're destined for a slower metabolism simply because you're getting older.In Part 2, we'll explore the individual factors that influence metabolism in more detail, including menopause, hormones, sex differences, relationships, lifestyle and practical strategies for navigating each stage of life.Enquire About CoachingReady to build a stronger, healthier body that serves you for life?Enquire about coaching here:https://forms.gle/9NujVMgsG1SZJ8Ec7Want to Chat to One of Us?Sean:https://www.instagram.com/seanskdcoaching?igsh=MW5kYzQxMGtxMzhtYQ==Katie:https://www.instagram.com/katieskdcoaching?igsh=OWxtdGt0MzVkeGh4&utm_source=qr
