Yesterday I posted about some interesting new research related to the link between “bad” fats (specifically butter and foods with trans fat) and depression, and as promised today’s post is about how this ties into weight loss. Here’s the connection:
A Wake Forest University study found that even at the exact same calorie and fat levels monkeys who gobbled trans fat gained four times more weight and 30% more belly fat compared to those who downed unsaturated fat like olive oil.
Another recent study found that saturated fats, like those found in butter, whole milk, and fatty meats, may override the body’s natural satiety (e.g. I feel full) mechanism, whereas unsaturated fats, from plant sources such as olive oil, avocado, and nuts, may enhance satiety, even when the calorie levels don’t differ.
And another study found that even at the exact same calorie level, meals made with unsaturated fat from walnuts and olive oil caused a 20 to 30 percent rise in post-meal calorie burning compared to meals made with saturated fat from whole-milk dairy products.
Pretty interesting huh? Bottom line: not all fats are created equal. All of this emerging research points to a major difference between how various types of fats impact your risk for heart disease, depression and obesity. So how can you this research to your advantage? Come back tomorrow – I’ll share some tips, including how to make cookies with olive oil instead of butter!
