Visceral fat tends to be eclipsed by subcutaneous fat because the latter is visible. However, visceral fat is much more deadly because it is found near organs such as the liver and intestines. Accumulation of fat therefore makes you particularly vulnerable to life-threatening complications.
Subjects were randomly assigned to the following processing oil-based diets: conventional canola, high oleic canola, high oleic canola with DHA (a type of omega-3 fatty acid) , corn / safflower and flax / safflower.
After each four week diet period, participants were given a four week break before starting the next diet period.
Participants consumed two smoothies during the day, which contained the specified treatment oil.
The amount of oil was calculated based on the participant’s energy needs. For example, a participant who was on a 3,000-calorie diet would receive 60 grams of processing oil per day, providing 18 percent of their total food energy.
Each smoothie would then contain 100 grams of orange sorbet, 100 grams of skim milk, 100 grams of unsweetened frozen strawberries and 30 grams of canola oil.
Canola oil was carefully incorporated into the test diets so as not to exceed participants’ daily calorie needs.
All of the participants had abdominal obesity or increased waist circumference.
“Typically, you can’t target weight loss at specific areas of the body,” Kris-Etherton said.
“But monounsaturated fatty acids seem to specifically target belly fat.”
Monounsaturated fatty acids are a healthy type of fat.
“Replacing less healthy fats, such as saturated fats and trans fats, with unsaturated fats, such as monounsaturated fats and polyunsaturated fats, may offer health benefits,” says the Mayo Clinic.
