Olive Oil
Olive oil contains a great number of healthy fats. Some studies have also found that this oil can help accelerate metabolism and help you burn fat quicker.
A study [4] involving 12 postmenopausal women who had abdominal obesity found that consuming more virgin olive oil in their meals boosted the number of calories they burned for hours.
Aside from boosting metabolism and fat loss, olive oil also helps you increase your levels of good cholesterol and lower triglycerides. You can add olive oil to your diet by using it to cook or sprinkling a lit bit over salad before eating.
