What are good and bad fats?
Low-fat items receive a lot of publicity, but adults are actually supposed to get 20-35 percent of their calories from fat, according to current dietary guidelines. The key is to steer away from saturated fats and seek unsaturated and monosaturated fats, which are found in nuts; seeds; oils like corn, safflower and olive; and many kinds of fish and avocados. Here's how you can tell the difference when cooking : unsaturated fats remain liquid when at room temperature, while saturated fats are solid like butter. Avoid transfat, too. And any time the words hydrogenated or shortening appear on a label, it's best to think twice.
What about carbs? Carbohydrates give the body fuel, so cutting them out completely can tailspin into fatigue and a plateau in metabolism. According to Health.Harvard.edu, there are benefits to both simple carbohydrates - found in fruit, table sugar, honey and dairy products - and complex carbohydrates - starches found in certain vegetables as well as crackers, bread, pasta and rice. Limit your intake of refined sugars such as cookies, cake or anything with high-fructose corn syrup. Try to focus on getting more complex carbs, which take longer to break down and are a better source of energy for the body.
