  1. Coconut Oil and it’s Health Benefits: What Role can iT Play in Weight Loss and Obesity Reduction? Presented by Julie A. Brier December 6, 2013

  2. Presentation Outline • MCFA structure and function • Composition of Coconut Oil (CO) • CO as a means to prevent and reduce obesity • Dietary Considerations and Recommendations • Supplementation vs. Food • Conclusions

  3. Coconut Oil Extraction • Dry Process • Clean, ground or steamed copra is pressed (most common method) • Wet Process • Extraction from Coconut Milk • Refined, Bleached, and Deodorized (RBD) • Carried on from Dry, Heated to 204-245°C, tailor made for cooking purposes • Fractionation • medium-chain fatty acids are separated for specific uses (LauricAcid,caprylic/capric triglyceride oil)

  4. Medium-Chain Triglycerides • 6-10 Carbon Saturated Fatty Acid • Absorbed directly into the portal circulation and transported to the liver for rapid oxidation http://www.rsc.org/images/44---feature-fat-structure_tcm18-34671.jpg

  5. Fatty Acids composition of Coconut Oil

  6. Impact on Energy Expenditure and Thermogenesis Ogawa et al. (2007) Scalfi et al. (1991)

  7. Thermogenesis and Energy Expenditure Cont. St-Onge MP and Jones PJH (2002)

  8. Eating Fat to Reduce Fat? One tablespoon contains 117 calories and 13.6 grams of fat http://www.mayoclinic.com/health/coconut-oil-and-weight-loss/AN01899

  9. Reductions in Abdominal Fat “The ingestion of coconut oil did not produce undesirable alterations in the lipid profile of women presenting abdominal obesity, although dietary supplementation with this oil did give rise to a reduction in WC, which is considered to confer some protection against CVDs.” (Assunc¸a˜o et al., 2009)

  10. Impact on Food Intake and Satiety • Pre-absorbative effect • Production of ketones that suppress hunger • A hyperinsulinemic response because of the ketones • Satiated by the first meal as they absorb the entire fat nutrient at the time of ingestion leading to decreased intake at second meal Clegg ME (2010)

  11. Discrepancies in the Literature • Weight and Health Status of Subjects • Lack of Males v.s Female Comparison Studies • Variations in Length of Feeding • Origin of MCFAs (most combination of oils)

  12. Supplementation and Dietary Use Should I supplement? Should I use it when I cook?

  13. Coconut Oil Products/Promotions • “Eat Fat, Look Thin” and “The Coconut Oil Miracle” (Bruce Fife, ND) • Tropical Traditions • http://www.tropicaltraditions.com/faq.htm#1
