Dr. Jones and his group provided interesting and valuable data that supports the inclusion of olive oil in the diet for fat-burning as well as health benefits. As always, there remains a number of questions such as: whether it behooves a person long-term to consume 50+ grams of olive oil with his breakfast; if there may be an optimal timing of consuming oleic acid (e.g., at night to promote calorie and fat-burning during sleep); if the effects are more potent when the olive oil is consumed with a meal or without for those who can stand chugging a couple healthy swallows; if the power of the effect changes when the macronutrient ratio changes (since few people follow a 60 percent fat diet); if the effect persists or the body adapts to the high oleic acid content and downregulates the relevant metabolic pathways; if the lean and the obese respond similarly; if purified oleic acid provides the same effect as olive oil; etc.
As part of the Mediterranean diet, olive oil has proven its health benefits; the results of this study certainly support its inclusion in anyone’s diet. Whether or not olive oil may aid in noticeable weight loss and fat-burning absent any calorie restriction remains to be seen. As effervescent and inspiring as she is, Rachael Ray, the Food Channel® champion of EVOO (extra-virgin olive oil) certainly is not known for her chiseled or athletic physique. However, one cannot deny her beauty, (my nephew thinks she’s a “hottie”) and that she is healthy, happy and most certainly prosperous.
