Types of Bread for Weight Loss : The popularity of the Atkins Diet and the explosive growth of low-carb diet plans have led people to believe that carbohydrates are the worst possible food to eat when trying to lose weight. The United States Department of Agriculture (USDA) thinks differently. In fact, the USDA has placed carbohydrates at the base of the food pyramid, suggesting that we should eat nearly twice as many carbs as vegetables or fruits. In truth, no one should do without carbohydrates. The trick is simply picking the rights carbs to eat because some are better than others at helping to promote healthy weight.
