Eating fats do not make you fat.

Many will not hear about "insulin resistance" from their doctors. Even more will not have had their insulin levels tested. As a country, we seem to be slow on recognizing the significance of insulin as a marker for our health. While the actual test is not costly; most doctors will still be reluctant to offer such tests. IMO, it could be because it would call the recommendations to have 3/4 plate carbs into question as carbs raise blood sugar which then spikes insulin. High level of insulin leads to fat/weight gain. In addition, consistently prolonged (years) high levels of insulin leads to insulin resistance. If you have been gaining weight over the years, there is your evidence. Hard as it may be to accept. Eating fats do not make you fat.
