Is your weight controlled by calories or insulin?

What really matters for weight loss? Calories in and calories out, or is our body weight carefully regulated by hormones, like the fat-storing hormone insulin?

In this presentation from the 2015 LCHF Conference in Cape Town I describe why the second explanation – about hormones – makes much more sense. And why the first one – about calories – is a simplistic description that completely fails to address the cause of obesity.

You can watch a segment above. For the full presentation you can buy access to the entire LCHF convention for $49 dollars from the organizers.
