Carbs make you gain weight. Carbohydrates are part of a healthy diet. Weight gain is not due to carbs themselves, but from over consumption of large portions of any type of food. Aim to eat complex, whole grains instead of refined grains. Whole grains are less processed and contain more fiber, which is key to maintaining a healthy weight. The 2015 Dietary Guidelines for Americans recommend getting at least half of your grains from whole grain sources, such as 100% whole wheat bread, quinoa, brown rice, and whole grain pasta. Limit consumption of refined grains, such as chips, crackers, white bread and pastries. Weight loss is best achieved by limiting overall calories, consuming whole grains, lean proteins, low-fat or fat-free dairy products, and eating lots of fruits and vegetables.
