Your body does need a little fat to process vitamins and use them properly. Olive oil is a mono-unsaturated fat that is the primary source of fat in the so-called Mediterranean diet. It contains antioxidants, flavonoids, beta- carotene and vitamin E, among other things. One tablespoon has a whopping 125 calories, but drizzled on a 13 calorie spinach salad with a little lemon juice and some garlic, you still have a meal with less than 150 calories - and a whole lot of healthy fuel for your body.
Diet Food: Pink Grapefruit
With only 40 calories in half a grapefruit, you're getting 45 mg of vitamin C, lycopene, pectin, beta-carotene and potassium. It's versatile and tasty. Eat it as is for breakfast, or toss it into a salad with spinach for an extra punch to perk up the nutritional quality of your diet.
Most importantly, don't base your diet around any single ONE ingredient. The best way to lose weight is to eat a healthy variety of foods to make sure that you get all the essential nutrients that you need each day.
