VIDEO DESCRIPTION
A common claim in many YouTube videos and other posts on social media as well as numerous nutrition books is that eating a high-carb diet is a major cause of insulin resistance. The argument is that eating a high-carb diet leads to regular increases not just in blood sugar, but also in blood insulin levels and that the cells of the body become ‘numb’, i.e. resistant, to the effect of insulin over time due to this excessive exposure to insulin.

In this video, we are assessing whether this claim is supported by scientific evidence.
