You already know that foods rich in saturated fats are about as good for your arteries as pouring superglue in them. But not all fats deserve a bad rap.Foods with healthy fats are not only good for your heart, but they also make the best go-to snacks for controlling hunger and promoting weight loss, according to chief medical consultant for “The Dr. Oz Show” and co-founder of YouBeauty, Mike Roizen, M.D. This includes the healthy fats found in safflower, coconut, cod liver, olive and canola oils, as well as omega-3 DHA, walnuts, macadamia nuts and chia seeds. In short, these oils and the foods that contain them can promote weight loss and waist loss.After reviewing findings with the Cleveland Clinic, Dr. Roizen says that your best bet is to have these oils before a meal. “My best estimate and that of the Cleveland Clinic committee were that two tablespoons of these oils first thing in the morning and at the start of every meal works,” he says. “All data look similar for weight and waist loss and appetite control using oils and non-cooked foods with these oils in this way, whether safflower, coconut, walnut, fish, olive or macadamia oil.”See the slimming snacks you should be snacking on.
