Triglycerides, APOB and cardiovascular risk

I’m joined by Dr Robert Eckel to unpack why obesity is far more complex than a BMI number and why insulin resistance plays such a central role in cardiometabolic disease.

We discuss preclinical versus clinical obesity, fat distribution, metabolic risk, and what actually improves health outcomes beyond weight loss alone.

What We Cover

• Why BMI is only a starting point
• Preclinical versus clinical obesity explained
• Why visceral fat matters more than total fat
• How insulin resistance develops with excess body fat
• Who may benefit most from weight loss interventions
• GLP-1 therapies, benefits and open questions

A practical, evidence-based conversation that reframes how we think about obesity, risk and long term health.
