Your appetite rests on a simple set of principles: When you’re hungry, you eat, and when you eat, you become full. It’s a predictable pattern—but what happens when it stops working, and you feel hungry even after eating?
“It’s normal to feel that your appetite fluctuates a little day to day, but if you’re noticing a persistent sense of hunger after every meal, even when you think you’ve eaten enough, I’d recommend a quick audit of any other lifestyle factors or life stressors that might be in play,” Maddie Pasquariello, MS, RDN, who runs the Brooklyn-based practice Nutrition With Maddie, tells SELF. Many, but not all, of these factors can result in food noise—“compulsive and often disruptive thoughts about food,” she explains. “Cravings and compulsions around food can be distracting, and even if you think you’ve eaten enough, your body might not feel fully satisfied or satiated.”
Here’s a detailed rundown of some of the physical and psychological forces that could be behind your ongoing postprandial hunger—and how to tackle each of them. Whatever the cause, “it’s important you don’t completely ignore what’s going on,” Pasquariello says.
Why you might feel hungry even after eating
1. You have a medical condition or take a medication that increases your appetite
How this works: Certain meds can heighten your sense of hunger and overall desire to eat, Pasquariello says. These include a range of psychiatric meds, such as the antidepressants amitriptyline, citalopram, mirtazapine, nortriptyline, trimipramine, paroxetine, and phenelzine; the antipsychotics olanzapine, risperidone, and quetiapine; and the mood stabilizers lithium, valproic acid, divalproex sodium, carbamazepine, and lamotriginelithium, which are commonly used to treat bipolar disorder. Similarly, certain medical conditions and symptoms can also impose consistent hunger, including hypothyroidism, PMS, and perimenopause.
What to do about it: In addition to basic healthy-lifestyle pillars—eating a balanced diet, drinking plenty of water, staying physically active, getting enough sleep, and managing stress—prioritizing veggies and high-fiber whole grains, keeping your pantry stocked with healthy options, and sticking to a regular eating schedule can all help cushion the impact, according to the BC Children’s Hospital in Canada. If nothing helps and you’re not willing to tolerate this side effect, you can also speak to your doctor about your options, like switching to an alternative medication that might be a better fit or starting another one that could counterbalance it, per Harvard Health.
2. You didn’t eat enough
How this works: Obviously, the amount of food you eat is the main driver behind your sense of fullness, so it’s possible the amount you ate wasn’t sufficient—especially since your calorie needs aren’t fixed. “What feels sufficient for your body one day might fluctuate the next, depending on how active you have been, your workout style, and other factors. And what’s sufficient for one person is going to be completely different for someone else,” Pasquariello says. Cardio exercises like running, swimming, and cycling tend to bestow a bigger burn than strength training exercises like weight-lifting, for example. Besides physical activity, pregnancy and breastfeeding can also significantly boost your calorie needs.
What to do about it: While calorie-counting isn’t something we typically recommend, tracking your food intake and macro breakdown could be helpful for sussing out patterns in this case, according to Pasquariello. You might realize you’re “under-eating at certain meals, leading to unpredictable hunger levels later in the day,” Pasquariello says. In addition to monitoring your stats, you can also consider tacking on a nutrient-dense snack to every meal to add a little more bulk. That’s “a great place to start,” Pasquariello says. If calorie counting is triggering for you, or something you’re not interested in pursuing for any reason, we recommend reaching out to a registered dietitian who can help you ID patterns and tailor your meal prep.
