Effects of caffeine on hormones

Caffeine in coffee changes your hormones. It can lower ghrelin in your body for a while. Ghrelin is the hormone that tells you when to eat. After you drink coffee, you may not feel hungry for one to two hours.

But caffeine also cuts down leptin in your body. Leptin is the hormone that says if you’re full or not! With less leptin, your body might tell you it’s time to eat even if it’s not true.

So after taking coffee, it can make your belly ask for more food!

Effects of caffeine on blood sugar levels

Caffeine in coffee can affect your blood sugar levels. When you drink coffee, caffeine can cause a spike in your blood sugar levels. This happens because caffeine stimulates the release of a hormone called adrenaline, which then triggers the liver to release stored glucose into the bloodstream.

The increase in blood sugar can give you quick energy but may also lead to feelings of hunger afterwards when your blood sugar drops again. So, if you feel hungry after drinking coffee, it could be due to this fluctuation in blood sugar levels caused by caffeine’s effects on hormones and glucose release from the liver.

Reasons Why You Feel Hungry After Drinking Coffee

– Loss of calories due to increased metabolism.

– Cramping in your belly triggers hunger signals.

– Sugar spike and subsequent crash lead to increased appetite.

Loss of calories

Drinking coffee can actually help you burn calories. The caffeine in coffee acts as a stimulant, which increases your metabolism and fat-burning ability. This means that when you drink coffee, your body is working harder to process the caffeine, resulting in an increase in calorie burning.

So even though you might feel hungry after drinking coffee, it’s important to remember that it can also help with weight loss by boosting your energy expenditure.

Cramping in your belly

Drinking coffee can sometimes make you feel cramping in your belly. This is because coffee stimulates the production of stomach acid, which can irritate the lining of your stomach and cause discomfort.

Additionally, caffeine in coffee acts as a diuretic, which means it can increase urine production and lead to dehydration. Dehydration can contribute to abdominal cramping as well.

To avoid or reduce this issue, try drinking coffee in moderation and make sure to stay hydrated by drinking plenty of water throughout the day.

Sugar spike and crash

When you drink coffee that has sugar in it, your blood sugar levels can spike. This sudden increase in blood sugar may make you feel hungry because your body wants to balance out the high levels of sugar.

However, this spike is usually followed by a crash in blood sugar levels, which can leave you feeling even hungrier than before. It’s important to be mindful of the amount of sugar you add to your coffee and consider opting for healthier alternatives like natural sweeteners or reducing the overall amount of added sugars in your diet.

Association with food

Drinking coffee is often associated with certain types of food, such as pastries or breakfast items. When we see or smell these foods while enjoying our coffee, it can trigger hunger signals in our brain.

This association between coffee and food may explain why we feel hungry after drinking it. Additionally, the potential sugar content in some coffees can cause a spike in blood sugar levels, leading to increased feelings of hunger.

So, if you find yourself reaching for a snack after your morning cup of joe, it could be due to this connection between coffee and food.

Is Feeling Hungry After Drinking Coffee Healthy?

Feeling hungry after drinking coffee is not necessarily unhealthy. It can be a normal response to the effects of caffeine on your body. However, it’s important to understand why you may feel hungry and how it can affect your overall health.

One reason for feeling hungry after drinking coffee is the temporary decrease in ghrelin levels. Ghrelin is a hormone that stimulates hunger, and when you drink coffee, it can temporarily lower these levels, making you feel less satisfied.

Additionally, consuming sugar in your coffee can cause a spike in blood sugar levels. This spike can lead to feelings of hunger as your body tries to regulate its glucose levels.

Furthermore, the association between coffee and food can also trigger hunger. If you often pair your coffee with snacks or meals, your brain may start associating the two together, leading to increased appetite when you consume coffee alone.

While feeling hungry after drinking coffee is generally not harmful, extreme hunger could indicate other factors such as excessive sugar consumption or inadequate food intake. It’s essential to listen to your body’s signals and make sure you’re fueling yourself properly with nutritious meals throughout the day.

In conclusion, while feeling hungry after drinking coffee is normal due to the effects of caffeine on hormones and blood sugar levels, it’s crucial to pay attention to potential underlying issues such as excessive sugar consumption or inadequate nutrition.

Remember that balance is key when it comes to maintaining a healthy lifestyle.


In conclusion, drinking coffee can make you feel hungry due to the effects of caffeine on hormones and blood sugar levels. It can also lead to a loss of calories and stimulate cravings for food.

While feeling hungry after drinking coffee is not necessarily unhealthy, it’s important to be mindful of excessive sugar consumption and ensure an adequate intake of nutrients. Remember that the impact of coffee on appetite can vary from person to person, so listen to your body and make choices that work best for you.

Adding evaporated milk versus half and half to coffee may affect hunger levels. While evaporated milk is thicker and creamier, half and half has lower fat content. Choosing between the two may depend on personal preferences and dietary needs. Experimenting with different options can help determine which one keeps you satisfied for longer without impacting hunger levels.

2. Does drinking coffee always lead to increased hunger?

Not everyone will feel an increase in hunger after drinking coffee, as it can depend on factors like how much sugar is added and individual metabolism rates.

3. Can coffee affect weight loss or calorie burning?

Yes, both the caffeine in coffee and appetite suppression linked with it might play a role in weight loss and speed up calorie burning, though this also depends on other dietary habits.
