Ultra‑Processed Foods vs Whole Foods

What if everything you’ve believed about “fast” and “slow” metabolism has quietly been steering you off course? And what if the real barriers to sustainable fat loss have less to do with willpower, and far more to do with how your body protects you when it senses scarcity?

This week on Live Well Be Well, I’m joined once again by Dr. Andy Galpin, professor of kinesiology and one of the world’s leading experts on human performance and metabolism. Together, we explore the truths behind fat loss, metabolic rate, weight cycling, and the misunderstandings that keep so many people stuck in frustration.

Here’s What We Dive Into:

- Why the idea of “fast versus slow metabolism” misleads us and what metabolic rate actually reflects.

- How fat oxidation differs from real fat loss and why marketing often blurs the line.

- What boosts metabolism acutely versus chronically and why most fat burners rarely matter.

- How basal metabolic rate, thermal effect of food, exercise and NEAT interact to shape long-term weight outcomes.

- Why sustainability is the strongest predictor of successful and lasting fat loss.

- How the body adapts to caloric deficit and why NEAT drops more than most people realise.

- What strategic refeeds can support and when they matter most for mood, hormones and motivation.

- Why GLP-1 medications are reshaping obesity treatment and what gaps still concern experts.

- How food confusion, ultra-processed marketing and seed oil panic distract from the fundamentals.

- What whole food patterns, education and self-awareness offer that shortcuts cannot replicate.

Love,

Sarah Ann 💛
