Diet Myth #3: Pasta Makes You Fat
The problem with pasta is not the pasta itself—it’s more about portions. If you eat too much of anything, and don’t burn it off, your body will store it as fat. So whether it’s bread or pasta or rice, it’s about the volume and extra calories, not about the carbohydrates themselves. Add to that the heavy sauces and high-calorie cheeses, and no wonder pasta has such a bad rap.

They key here is practicing portion control. Pasta is okay in moderation. Dietitians recommend 2 or 3 ounces of uncooked noodles per person, or half of a one-pound box to serve a family of four.

Diet Myth #4: Eating After 8 p.m. Will Make You Put on Weight
There is some truth to this myth. Dr. Oz recommends not eating after 8 p.m. because studies have shown that you are more likely to overeat and misjudge how many calories you consume when you eat late. Fatigue may be to blame here as it may cause you to eat too much of the wrong foods, causing you to put on weight.

However, it’s not the time of day that makes you gain weight—it’s the extra calories! It does not matter when you consume the calories—if you exceed your recommended calorie intake, what you don’t burn will be stored as fat. Always be vigilant of how many calories you consume throughout the day. A healthy woman should consume between 1800-2000 calories a day.
