Fat metabolism in human obesity

PJ Campbell, MG Carlson… - American Journal of …, 1994 - journals.physiology.org
Excessive fat turnover and oxidation might cause the insulin resistance of carbohydrate
metabolism in obese humans. We studied the response of free fatty acid (FFA) metabolism …

Long-and medium-chain fatty acids induce insulin resistance to a similar extent in humans despite marked differences in muscle fat accumulation

J Hoeks, M Mensink, MKC Hesselink… - The Journal of …, 2012 - academic.oup.com
Context: Animal studies revealed that medium-chain fatty acids (MCFA), due to their

Regulation of dietary fatty acid entrapment in subcutaneous adipose tissue and skeletal muscle

K Evans, GC Burdge, SA Wootton, ML Clark… - Diabetes, 2002 - Am Diabetes Assoc
Using stable isotopic labeling of dietary fatty acids in conjunction with arteriovenous

Adipose tissue free fatty acid storage in vivo: effects of insulin versus niacin as a control for suppression of lipolysis

AH Ali, M Mundi, C Koutsari, DA Bernlohr… - Diabetes, 2015 - Am Diabetes Assoc
Insulin stimulates the translocation fatty acid transport protein 1 (FATP1) to plasma
membrane, and thus greater free fatty acid (FFA) uptake, in adipocyte cell models. Whether …

Insulin resistance after a 3-day fast is associated with an increased capacity of skeletal muscle to oxidize lipids

SJ Blackwood, O Horwath, M Moberg… - American Journal …, 2023 - journals.physiology.org
There is a debate on whether lipid-mediated insulin resistance derives from an increased or
decreased capacity of muscle to oxidize fats. Here, we examine the involvement of muscle …

Free fatty acids and insulin resistance

J Delarue, C Magnan - Current Opinion in Clinical Nutrition & …, 2007 - journals.lww.com
