The Glycemic Index Diet for Dummies - Meri Raffetto [86]
Lack of sleep: Recent research shows that people who don't get the appropriate amount of sleep at night produce more of their "hunger hormone" and less of their "full hormone," leading them to feel hungrier during the day, overeat, and consequently gain weight. The study also found that these people had more cravings for salty and sweet foods throughout the day. To counteract this physiological trigger of food cravings, allow yourself seven to nine hours of sleep each night. If you have sleep problems, contact your doctor for professional help.
Can't wind down at night? Try drinking a cup of chamomile tea, doing a few yoga stretches, reading, meditating, journaling, or any other activity capable of turning off your mental to-do list.
Low serotonin levels: Some researchers feel that a hormone imbalance, specifically low serotonin levels, may be another physiological trigger for food cravings. Scientific evidence also suggests that carbohydrates may help replenish the body's serotonin levels (serotonin is a feel-good brain chemical). Although there's no conclusive evidence that eating carbohydrates has a calming effect, it may be enough for a quick feel-good moment. Keeping your blood sugar stable and eating high-quality carbohydrates such as whole grains, fruits, and vegetables (rather than high-glycemic carbohydrates) can help. Exercise also increases serotonin levels and may help decrease food cravings. (For tips on adding exercise to your life, head to Chapter 21.)
Conditioned responses from childhood: One of the biggest psychological reasons people crave food is because they're conditioned to from childhood. Conditioned responses go hand in hand with emotional eating (I share tips for fighting emotional eating later in this chapter). Infants and young children learn through experience that certain foods make them feel better or even make them feel full or emotionally satisfied. Perhaps you always had dessert after dinner as a child, or maybe you got ice cream when you lost the soccer game. Some of these conditioning cues are okay because they're once-in-a-while things, but some are tougher because they're daily habits. For instance, if as a child you were rewarded with sweets each day for doing your chores, you may continuehis pattern as an adult, thinking "I worked hard today; I deserve this."
To break away from your conditioned food responses, you may be tempted to cut out the food altogether, but doing so will only make your craving worse. Instead, eat something similar. If you're craving ice cream at night because that's what you ate before bed when you were little, then have a small amount of frozen yogurt or a fruit smoothie. If you're craving chocolate, have an ounce of dark chocolate.
Restrictive dieting and restrained eating: Studies suggest that when people refrain from eating certain foods, they end up craving them more, giving into the craving, and overindulging. As a psychological response, they then feel guilty and decide to refrain from eating the foods, which only prolongs the food-craving cycle. Severe restrictive eating (found in very-low-calorie diets) can also result in a physiological trigger — low blood sugar from not eating! Instead of cutting yourself off from certain foods, eat small amounts of them. You can also try a lower-glycemic food that's similar to what you're craving.
Think about the last time you had a food craving. Can you point to your trigger? Becoming aware of why you crave certain foods can help you overcome and prevent these cravings in the future.
