We’ve all heard that healthy fats are essential—avocados, nuts, seeds, they’re supposed to be good for us, right? But here is a perspective that challenges the more is better mindset.
When excess fatty acids accumulate in the body, it can trigger something called lipid toxicity. It’s a mechanism where, even with healthy fat sources, overconsumption can actually corrupt the insulin receptor sites responsible for shuttling sugar into your muscles. Once those muscles stop accepting sugar, the body faces a cascade of metabolic issues—potentially paving the way for everything from Type 2 diabetes to metabolic decline.
Dietitian Myrna Haag, RD, LD/N, pulls back the curtain on how insulin response and muscle metabolism are not just buzzwords, but critical biological systems that dictate how our bodies handle fuel. Understanding the biochemistry behind your plate could be the missing link in stoping the diet-guessing game and finally aligning your nutrition with your body’s actual needs.
