But what if these strategies fail you? What do you do when you still have a hankering so intense, you struggle to focus on anything else?
That's when you need to take a look at your lifestyle and assess whether any of the following five issues may come into play.
Multiple studies in recent years have suggested that cardiovascular exercise is an effective way to suppress and manage hunger.
One recent study suggested that appetite can be better controlled by exercise than by simple restraint-take note, dieters who struggle to say "no!" But if you're chained to the cardio machines for hours on end at a moderate intensity, it could send your hunger soaring.
A study of German cyclists found that their production of the appetite-stimulating hormone ghrelin rose significantly after a 120-minute low-to-moderate intensity exercise session, but not nearly so much after high-intensity workouts of any duration.
Other recent studies have reinforced the notion that high-intensity workouts don't dramatically stimulate appetite. If you're stuck on the moderate intensity cardio bandwagon and feeling ravenous, now might be the time to up the intensity.
Of course, not all cardio is the same. One recent study, for instance, suggested that swimming can have a tendency to stimulate appetite in the hours following exercise.
If you find yourself climbing out of the pool and racing for the bakery, consider mixing cross-training into your routine.
It's no secret that sleep deprivation can damage your workout performance and make for a miserable recovery period, but it may also influence how well you can stick to your diet plan.
A study in the Journal of Sleep Research found that a single night of sleep deprivation caused subjects' reported hunger levels and their appetite-stimulating ghrelin levels to rise drastically. Other studies have reported similar findings for subjects who slept poorly over multiple nights.
These studies suggest a simple relationship: The less you sleep, the more you put yourself at risk for uncontrollable hunger. You probably don't need an academic study to tell you that if you're feeling tired and cranky after a bad night's sleep, it's going to be hard to stay positive about a diet.
Speaking of temptation, a growing body of research suggests that exposure to delicious food increases cravings. Big surprise, right?
The food you see in pictures, on television/Internet commercials, or on your coworker's desk can create a feeling of hunger in you. Smell is another powerful hunger stimulant. If you walk into a room filled with the aroma of delicious food, don't be surprised if your stomach starts rumbling.
It's almost impossible to totally shield yourself from hunger-spiking "food porn," but if you're feeling famished, it's probably a good idea to try.
One recent study found that people who struggled with weight control in the past are especially susceptible to the temptation brought on by exposure to food. If that describes you, do your best to build a wall around you!
Most of us have been conditioned to grow hungry at the typical meal times: in the morning after waking up, at midday, and in the early evening.
If you've switched over to a higher frequency meal plan, don't be surprised if you still experience some hunger when those old meal times hit.
This may be especially acute if those around you are eating, since hunger can be socially triggered.
If nostalgia for those three-squares-per-day impacts your ability to stick with your diet, then you may want to consider being flexible about your meal times and moving at least a couple of them in-line with the traditional times.
Your body will probably catch up to your new system with time, but you might feel a powerful hankering until it does!
If your shaker bottle has taken the place of your knife and fork, take note: A pair of recent studies at the Nutrim School of Nutrition found that solid protein meals are more effective in suppressing hunger than similar liquid protein meals.
The subjects received the same nutritional benefits from nutrient shakes and chicken breasts, but the difference was after the shake, they still felt hungry.
So while those supplements may help you to reach your fitness goals, don't forget that they're supplementing food!
