Hallberg and colleagues are currently in the midst of a study in which ten overweight mostly menopausal women, who have been doing low carb keto eating but whose weight loss has stalled prematurely, will spend about five days in a monitored environment. During this time the women’s food and activity will be observed and recorded and their metabolism analyzed. While studies like this have been done before, this is the first time the focus has been on women who have stalled in their weight loss on a low carb and high fat diet, Hallberg says. “Most of the other studies found it was overconsumption leading to the problem. We want to see what is happening for these women.”
As you start removing carbohydrates from your body, your body will begin using the glycogen stored in your liver and muscles as its primary fuel source. This is exactly what you want, because once your body gets through the glycogen, it will start burning fat instead of glucose. And when this happens, you’ve made it to the holy land: ketosis. We’ll talk more about this in Phase 2.
And monounsaturated fat isn't the only thing olive oil has going for it nutritionally. Some olive oils come with phytonutrients that may offer their own disease protection benefits (still, it's not clear whether most of us can take in enough of these phytonutrients without going overboard on olive oil, says Joyce Nettleton, DSc, RD, researcher and editor of the PUFA Newsletter).
