Episode 27 – Adipocytes and insulin resistance

Show notes:   60% of US adults are overweight to moderately obese but within that group there is great heterogeneity in their response to insulin ⇒ their degree of insulin sensitivity can vary more than sixfold at any given BMI within this range Adults constantly form and replace adipose cells, called turnover 2 places to measure fat are the femoral (leg fat) and subcutaneous (under your skin and predominantly white) adipose tissues For IMGU (insulin mediated glucose uptake), the higher

Episode 5 – how enlarged adipocytes overloaded with lipids lead to insulin resistance

 Episode 5 of the Break Nutrition Show Gabor and I  had a discussion about the paper called “Lipid-overloaded enlarged adipocytes provoke insulin resistance independent of inflammation”, covering the following points (and more): Link: http://www.ncbi.nlm.nih.gov/pubmed/25733684 The concept of IR occurring after the lipid-derived enlargement of adipocytes (as opposed to the other model of IR preceding it) The difference in mild/early-stage obesity versus severe/late-stage obesity Mechanisms whereby adipocyte-focused inflammation appears necessary to make adipocytes more insulin resistance in severe/late-stage obesity but not in
