Longevity is everywhere right now, but has it become a trend instead of a truth?

In a world overflowing with health hacks, supplements, and promises of a longer life, it has never been harder to know what actually works. Beneath the noise, there is a clear science to living well for longer, but only if we learn to tune out the hype and return to what our biology has been asking of us all along.

Today I am joined by Dr. Darshan Shah, medical doctor, longevity expert, and founder of Next Health. Dr. Shah became a doctor at 21 and has since guided thousands of patients through metabolic healing, functional medicine, and evidence-based longevity. Together, we explore what truly extends your healthspan and what does not.

This conversation is a practical and compassionate look at longevity, what it means, where to begin, and why most people focus on the wrong things. Dr. Shah breaks longevity into a simple health pyramid, starting with foundational habits, then biomarkers, hormones, detoxification, brain health, and emerging therapies such as peptides.

Here’s What We Dive Into:

- What longevity truly means, and why adding years is different from adding healthy years.

- Why metabolic health is the most important predictor of long term wellbeing.

- How simple habits before and after meals support better blood sugar regulation.

- Why quarterly biomarker testing may be the most effective prevention tool we have.

- What optimal blood ranges look like, and why normal ranges are not always healthy.

- How functional medicine identifies the eight root causes behind most chronic disease.

- Why toxins, microplastics, and everyday chemicals affect long term health.

- How women’s hormones, menopause, and brain health relate to Alzheimer’s risk.

- What creatine offers for muscles, cognition, and healthy aging.

- Why peptides are rising in popularity, and how to approach them with safety and clarity.

Love,

Sarah Ann 💛

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 💛
