Regulate appetite cravings -

Of course, individual cravings are brief and can vary in intensity, May said. While a person can resist a craving by stopping the mental elaboration, it's still possible that a new craving will pop up a few minutes later, he said. But studies have shown that trying these specific tasks may reduce the intensity of people's cravings as well as the amount they eat.

For example, in a study published in the journal Appetite , researchers found that women who looked at a smartphone app that showed a rapidly changing visual display whenever they had a craving reported that the craving became less intense.

What's more, they also consumed fewer calories over a two-week period. In another, shorter study , researchers found that asking college students to vividly imagine engaging in a favorite activity when a craving struck reduced the intensity of those cravings over a four-day period.

Since May first proposed the elaborated intrusion theory in , a number of other researchers have explored the theory, and there's a growing amount of evidence to support it. In , May wrote a retrospective detailing how the theory caught on in the world of cravings and addiction research.

Beyond our in-the-moment thoughts about food, the mechanisms in our bodies that regulate hunger are complex. Indeed, many factors beyond the foods we tend to eat on a daily basis can influence these mechanisms.

These factors include sleep, exercise and stress. Much research has shown that not getting enough sleep increases hunger , said Erin Hanlon, a research associate in endocrinology, diabetes and metabolism at the University of Chicago. For example, sleep restriction may lead to increases in ghrelin and decreases in leptin, according to the National Institutes of Health.

Shifts in leptin and ghrelin levels are thought to be involved more in homeostatic hunger, but there's growing evidence that sleep deprivation also may increase hedonic hunger, she said. Researchers know that when people's sleep is restricted, they report higher levels of hunger and appetite, Hanlon said.

But studies in laboratories have shown that sleep-deprived people seem to eat well beyond their caloric needs , suggesting that they're eating for reward and pleasure, she said. For example, Hanlon's February study, published in the journal Sleep, looked at one measurable aspect of hedonic eating: levels of endocannabinoids in the blood.

Endocannabinoids are compounds that activate the same receptors as the active ingredient in marijuana does, leading to increased feelings of pleasure. Endocannabinoid levels normally rise and fall throughout the day and are linked with eating.

However, it's unclear whether these compounds drive a person to eat or if, once a person starts eating, make it harder for him or her to stop, Hanlon said. The researchers found that in a hour period following sleep deprivation in which people slept 4.

Those peaks coincided with other measurements in the study, including when people reported being hungry and having increased desires to eat, and also when they reported eating more snacks, according to the study. Overall, the results of the study add further evidence to suggest that insufficient sleep plays an important role in eating and hunger, the researchers said.

But although there's growing evidence to suggest that not getting enough sleep increases both types of hunger, there's still the question of whether the reverse is true, too — namely, if people get more sleep, will they be less hungry?

Researchers have only just started looking into that question, Hanlon said. For example, some research has suggested that increasing sleep time may reduce cravings for certain foods, she said. But so far, most of these "sleep extension" studies have focused more on how sleep affects blood sugar levels than on which foods people choose and how much they eat, she said.

Therefore, more research is needed to answer these questions. To anyone who's ever felt ravenous after working out, the idea that exercise can suppress appetite may sound counterintuitive.

But some research suggests that certain types of physical activity — namely, a short, intense workout — may suppress levels of the hormones known to drive appetite. Based on the scientific literature, "it certainly seems that exercise would decrease the appetite-stimulating hormone ghrelin," said Tom Hazell, an assistant professor of kinesiology and physical education at Wilfrid Laurier University in Canada.

However, not all studies on this topic have shown this effect, he added. Exercise also appears to increase levels of other hormones, such as cholecystokinin and peptide YY, which play a role in inhibiting appetite, Hazell told Live Science. However, more research into precisely how exercise affects the suppression and release of these hormones is needed, he said.

This is still a relatively new topic of research, he added. But not all types of exercise appear to have the same effect. Most people actually feel hungrier after doing low- to moderate-intensity exercise, Hazell said, and this is the preferred type of workout for many people.

It seems logical that the body would try to replenish the energy it used during exercise, and when the intensity is low to moderate, it's relatively easy to do so after exercise, Hazell said. In other words, to restore balance, the body wants to eat food to replace the calories it just burned.

But, in contrast, when someone does a high-intensity workout, the body experiences many more changes in metabolism than just losing calories, he said. So although the body does want to replenish its energy stores, it prioritizes dealing with these other changes before doing so, he said.

All of this begs the question, if you're feeling hungry, could exercise possibly squash the feeling? Exercising around times when you know hunger tends to strike "could be an interesting preemptive option too," he added, though this idea has not yet been looked at in a formal study.

When it comes to factors that influence eating, it's hard to ignore good old stress eating. But different types of stress can have different effects on different people, said Dr.

Michael Lutter, a psychiatrist at the University of Iowa. Major stressors — such as war, famine and severe trauma — are associated with an increased risk of developing serious mental illnesses, such as major depression and post-traumatic stress disorder , both of which have been linked to changes in appetite, said Lutter, who has researched the neurological basis of feeding and disordered eating.

But the data on whether mild stressors — the kinds people experience on a day-to-day basis — can trigger hunger is less clear, Lutter said. In surveys, about 40 percent of people report that they eat in response to stress, but another 40 percent say they experience a decrease in their appetite in response to stress, he said.

As for the remaining 20 percent? They report no effect, Lutter said. It's also unclear what's going on in the body to drive stress-induced eating. But this link was based on research showing that high levels of cortisol — resulting from either medication or an illness — could affect metabolism, he said.

Mild stress also causes cortisol levels to rise acutely; but these increases are much smaller and do not last as long, so it's not entirely clear how much "stress-induced" changes in cortisol drive comfort eating, he said.

Rather, "ghrelin, and possibly leptin, also likely contribute to changes in food intake and body weight in response to chronic stress," Lutter said.

However, the strongest data for this is in mice, not in humans, he added. Eating slowly doesn't always work, but when it does, the reason has as much to do with the brain as with the gut. Scientists have known for some time that the fullness of your stomach is only part of what makes you feel satisfied after a meal; the brain must also receive a series of signals from digestive hormones secreted by the gastrointestinal tract.

The complex signals that control appetite are only partially understood, but by eating too quickly, you might not give this intricate hormonal cross-talk system enough time to work.
