Can Coffee Make You Gain Weight?

It’s interesting to think about how coffee affects weight. Coffee, which is loved all over the world for its rich taste and ability to wake people up, may have an effect on how much we weigh. 

But just what is this connection? Does coffee help you lose weight or make you gain weight? This study looks at what scientists have found out about these questions.


Coffee and Weight: An Overview

Coffee is a complex beverage. It’s not just water and coffee beans. It contains hundreds of different compounds, some of which can affect body weight. However, its effect on weight can depend on many factors, including the type of coffee, how it’s prepared, and individual metabolism.

The Popularity of Coffee

Coffee is undeniably one of the world’s most popular beverages. According to the National Coffee Association, 62% of Americans drink coffee daily. This prevalence prompts many to explore its potential effects on health and body weight.

The Mixed Effects of Coffee on Weight Management

Scientific research on coffee’s impact on weight has yielded mixed results. Some studies suggest potential benefits for weight loss, while others indicate possible risks for weight gain.

Potential Weight Loss Benefits of Coffee

Potential Weight Loss Benefits of Coffee

Coffee, specifically black coffee, has been associated with potential weight loss benefits. This can be attributed to several factors:

How Black Coffee Might Aid in Weight Loss

Black coffee is coffee that is served without milk, cream, or sugar. It is low in calories, with a standard 8-ounce serving containing only 2 calories. Its low-calorie content makes it a sensible choice for those trying to lose or manage weight.

Moreover, black coffee contains chlorogenic acid, a type of antioxidant. Research suggests that chlorogenic acid can slow the absorption of carbohydrates and potentially aid weight loss.

Coffee’s Role in Calorie Intake and Metabolism

Coffee also plays a role in metabolism, which is the process by which your body converts what you eat and drink into energy. Caffeine, the main stimulant in coffee, is known to increase resting metabolic rate. This means that caffeine can help your body burn more calories even when it’s at rest.

How Caffeine May Affect Appetite

Additionally, caffeine has been shown to affect hunger. According to the findings of a number of studies, caffeine use is associated with a brief decline in appetite, which may be followed by a reduction in calorie consumption. However, more research is needed in this area to understand the long-term effects of caffeine on appetite and weight management.

Potential Weight Gain Risks of Coffee

Potential Weight Gain Risks of Coffee

While coffee has potential weight loss benefits, it’s important to note that it can also contribute to weight gain in some circumstances.

How Coffee Could Negatively Impact Weight

Short-term, caffeine may speed up your metabolism and make you less hungry, but these benefits may wear off if you drink it often and for a long time. Some studies show that if you drink a lot of caffeine over a long period of time, you may develop a tolerance to it. This means that its effects on your metabolism and hunger may change over time.

The Potential Pitfalls of Specialty Coffee Drinks

Specialty coffee drinks, such as lattes, mochas, and frappuccinos, often contain high levels of sugar and fat, significantly increasing their calorie content. Consuming these beverages regularly can contribute to an excess calorie intake, which can lead to weight gain over time.

The Impact of High-Calorie Additives in Coffee

Even regular coffee can contribute to weight gain if it’s loaded with high-calorie additives. Adding cream, sugar, or flavored syrups can significantly increase a cup of coffee’s calorie content.

How Sugar Substitutes in Coffee Might Affect Weight

Some people use sugar substitutes, like artificial sweeteners, to reduce the calorie content of their coffee. However, some research suggests that these sweeteners could lead to weight gain by increasing cravings for sweet foods and drinks.

Coffee and sleep

Another aspect to consider when discussing coffee and weight is its impact on sleep.

The Stimulant Effects of Coffee and How It Might Impact Sleep

Caffeine, the primary active ingredient in coffee, is a stimulant. It can help you feel more alert and less tired. However, it can also interfere with sleep if consumed too close to bedtime.

How Poor Sleep Quality Could Relate to Weight Gain

Poor sleep quality has been linked to weight gain. Sleep deprivation can disrupt the balance of hormones that regulate hunger and satiety, leading to increased appetite and potential weight gain. So, if coffee consumption is interfering with sleep, it could indirectly contribute to weight gain.

Coffee as a meal replacement

Coffee as a Meal Replacement

It’s also important to discuss the trend of using coffee as a meal replacement:

Why Coffee Should Not Replace Meals

While coffee can suppress appetite and increase metabolism, it should not be used as a substitute for a balanced, nutritious meal. Coffee does not provide the necessary nutrients that our bodies need, and using it as a meal replacement can lead to nutrient deficiencies and potential weight gain in the long term.


The relationship between coffee and weight is complex. On one hand, coffee, particularly black coffee, can offer potential weight loss benefits by boosting metabolism and reducing appetite. On the other hand, factors like high-calorie additives, sugar substitutes, sleep disruption, and using coffee as a meal replacement could contribute to weight gain. The key is to consume coffee mindfully and in moderation, keeping in mind that the potential effects can vary from person to person.

Frequently Asked Questions:

Is coffee fattening?

Coffee itself is not fattening. A cup of black coffee contains only a few calories. However, adding cream, sugar, or other high-calorie additives can significantly increase its calorie content.

Can coffee make you lose weight?

Coffee may aid in weight loss by increasing metabolism and reducing appetite. However, these effects are usually temporary and may diminish with regular and prolonged consumption.

Can drinking coffee cause weight gain?

Drinking coffee can potentially contribute to weight gain, particularly when consumed with high-calorie additives or as high-sugar specialty drinks. Additionally, if coffee consumption disrupts your sleep, it could indirectly contribute to weight gain.

Should I replace meals with coffee?

No, coffee should not be used as a substitute for meals. While it can suppress appetite, coffee does not provide the necessary nutrients that our bodies need. Using it as a meal replacement can lead to nutrient deficiencies and potential weight gain in the long term.
