This particular type of carb leads to weight gain and dangerous blood sugar spikes.
According to research by Katherine L. Tucker, PhD, of the Jean Mayer USDA Human Nutrition Research Center on Aging, Tufts University, people who eat three or four servings daily of foods made with white flour (including white bread, wheat bread, bagels, muffins, pancakes, cookies, pies, and cakes) have significantly larger waistlines than people whose carbs come primarily from whole grains.
That's not surprising when you understand that refined flour and the baked goods and cereals made from them are treated almost the same as white sugar in your body. They cause rapid blood sugar spikes, which cause your pancreas (the organ just below your ribs on the left side of your abdomen that regulates digestion and blood sugar) to secrete insulin.
How to Benefit: Avoid eating foods made with refined sugar or white or wheat flour. Over time your desire for these types of foods will diminish. If you're still craving sweets, eat a meal or a snack more often—about every 2 to 3 hours. Be sure your meal contains some protein foods like fish, chicken, nuts, seeds, tofu, or beans. Eating more healthy fats such as coconut oil, flaxseeds and flaxseed oil, avocado, and nuts can also help you feel full longer. You can also supplement with chromium.
Super Health Bonus: Eat moderate amounts of healthy carbs. They include most vegetables (sorry, potatoes don't work on a slimming program), whole grains, legumes, and fruit (eat fruit occasionally, and avoid pineapples and bananas until you've reached your target weight—and then eat them only in minimal amounts, because of the high amount of sugars they contain).
