Hunger is a biological response your body sends out when it is time to consume necessary nutrients that allow your body to thrive! While our body needs a specific set of nutrients, we often pick our foods according to what we are craving. While your cravings don’t necessarily have to be unhealthy, a lot of the time the food we are craving do not satiate our hunger. According to WebMD, hunger hormones and an empty stomach signal to the brain you want food, while nerves in the stomach communicate fullness once you eat. However, this feedback loop isn't instantaneous, it can take up to 20 minutes for your brain to register satiety. It is very easy to give in and end up overeating, but you must pay attention to your hunger cues. There are many reasons why you may end up feeling hungrier than usual or even right after you eat, hence it is wise to eat too quickly. Here are some other reasons why you may be feeling hungry even after eating food. Not Enough Protein in Your Diet Protein is super important for feeling full. A 2006 study in Cell Metabolism showed that a high-protein diet boosts peptide YY (PYY), which is a hunger-suppressing hormone. It also helps your body build strong muscles and bones. If you're always hungry, try eating more eggs, chicken, beans, or yogurt. These foods help you stay full longer and keep you from snacking too much. Not Getting Enough Sleep When you don't sleep well, your body's hunger signals get mixed up. A 2007 study in Sleep Medicine Clinics confirmed that lack of sleep changes ghrelin and leptin levels, which in turn cause more appetite. Adults should aim for 7 to 9 hours of sleep each night. If you're older, try for 7 to 8 hours. Good sleep can help you control your appetite and eat healthier. Eating Too Many Refined Carbs Foods like white bread and sugary cereals don't have much fiber or nutrients. They give you a quick burst of energy, but you'll feel hungry again soon. Eating whole grains like oatmeal or whole wheat bread can help you feel full longer. Check food labels for added sugars like syrup and molasses. These sugars can make you feel hungry faster. Not Enough Healthy Fats in Your Food Healthy fats are important for feeling full and for your body to work right. A 2011 Obesity study indicated that low-fat diets resulted in higher hunger levels compared to low-carb diets. Eating foods with healthy fats can help you feel satisfied. If you find yourself always hungry, make sure to include healthy fats in your diet. Not Drinking Enough Water Sometimes, when you think you're hungry, you're actually thirsty. A 2018 Physiology & Behavior study found that increased water consumption suppressed energy intake. How much water you need depends on your activity level and health. Eating water-rich foods like watermelon can also help you stay hydrated. Not Eating Enough Fiber Fiber helps you feel full and satisfied after eating. It's found in fruits, vegetables, beans, and whole grains. Eating enough fiber can help you control your appetite. Add fiber to your diet slowly to avoid gas and bloating. Eating While Distracted If you eat while watching TV, you might not notice how much you're eating. A 2011 study in showed that distracted eating reduces feelings of fullness. Try to focus on your food and eat without distractions, this can help you feel more satisfied and eat the right amount. How Exercise Affects Hunger Doing a lot of exercise, especially lifting weights, can make you feel hungrier. Not drinking enough water while exercising can also make you crave sugary and salty foods. Eating a snack before you exercise can help you avoid feeling too hungry. Make sure to drink plenty of water to stay hydrated and control your hunger. Drinking Too Much Alcohol Alcohol can make you feel hungrier. It can also make it harder for you to control how much you eat. A 2004 study showed that drinking alcohol, especially before meals, can lead to eating more calories. It can also lower your inhibitions, making you more likely to choose unhealthy foods. If you're trying to control your hunger, limit how much alcohol you drink.
