Do Energy Drinks Really Make You Fat? (Facts Spilled)

The claims made about energy drinks are bold. Some are true and some are just plain misleading. One popular claim is:

‘Energy drinks make you fat.’

It’s a vague claim, but it’s enough to grab your attention, especially if you’re a fan of energy drinks and staying healthy. But do they really? Do energy drinks make you fat?

The short answer is, sugary energy drinks might lead to weight gain, especially if consumed often. Although certain energy drinks utilize artificial sweeteners (which have no caloric value) as a sugar replacement, excessive use might still result in weight gain. However, energy drinks will have little to no influence on your weight if you consume them in the proper amount.

Prominent Ingredients in Energy Drinks

Let’s go through the usual ingredients found in energy drinks before getting into the specifics of their harmful effects. Then, we’ll talk about how they’re used and whether or not they have significant effects on our weight.

Because of its stimulating effects, caffeine is the most common ingredient found in energy drinks.

Caffeine works by blocking the adenosine receptors, a chemical in our bodies that promotes drowsiness). By doing so, it makes us feel more alert and awake. Moreover, Riboflavin (vitamin B-2), niacin (vitamin B-3), magnesium, potassium, and different phenolic compounds, or antioxidants, are among the nutrients found in coffee that prove to be beneficial.

Caffeine is a stimulant that works rapidly. Caffeine’s effects peak after 30-60 minutes of intake but gradually fade after 5 hours. It eventually leaves your system after about 12 hours, but it may cause side effects such as tiredness depending on your tolerance. 

Caffeine is an aid to most individuals who are always on the go or go to extremes, so it is extensively marketed in sports, in-office corridors or halls (vending machines), and even in universities.

Here are some other benefits of caffeine:

  • Improve energy levels
  • Can boost metabolic rate
  • Improve physical performance
  • Contains nutrients
  • Antioxidant

Although caffeine may be beneficial from time to time, overconsumption may lead to health risks. Some of these are:

  • Anxiety
  • High blood pressure
  • Insomnia
  • Jitteriness
  • Palpitations

The Right Amount of Caffeine

So what’s the right amount of caffeine?

Caffeine intake for healthy individuals should not exceed 400mg per day, according to the FDA. However, if you have a poor tolerance, 50-100mg of caffeine may be beneficial. Regardless of your tolerance, you should limit your caffeine use.

Does Caffeine Make You Gain Weight?

No, caffeine does not make you gain weight.

It does, however, negatively affect your sleep, which is a factor in weight gain. But as long as you consume the right dosage, caffeine will have minimal to no effect on your weight.

In fact, it contains antioxidants and is something that can boost your mood and physical performance.

Another typical component in energy drinks is sugar. Sugar is not only used to give beverages a sweet flavor, but it is also a calorie or carbohydrate that is converted into energy.

Energy drinks are made with a lot of sugar in them, but some companies are offering sugar-free energy drinks by using artificial sweeteners instead.

Surprisingly, sugar, in adequate amounts, may be beneficial. Here are some of the ways sugar is helpful for you:

  • Can give you immediate burst of energy
  • Helps store energy for later use
  • Can improve thinking skills
  • Has added nutrients

The American Heart Association (AHA) advised a specific quantity of sugar per day. About 6 teaspoons (24g) for women, and no more than 9 teaspoons (36g) for men.

Excessive consumption may lead to:

  • Causes blood sugar to plummet
  • Increases risk of obesity and heart diseases
  • Accelerates aging
  • Interferes with immune function
  • Causes tooth problems

Does Sugar Make You Gain Weight?

Sugar makes you gain weight if you take excessive amounts of it.

Since sugar is a type of carbohydrate and calorie, eating excessive amounts may lead to weight gain and even chronic health issues such as heart diseases.

Moreover, sugar is often high in calories while it offers few nutrients. It also impacts hormonal levels like elevating blood sugar levels which can then, in turn, cause serious harm to your body, including weight gain.

Excess sugar consumption can lead to overeating by raising the levels of the hunger-promoting hormone ghrelin while decreasing the appetite-suppressing hormone peptide.

To know more about the significance of excessive amounts of sugar in weight gain, here’s a video by UW Medicine:

Now that you have a quick overview of how prominent ingredients in energy drinks work and how they may be significant in weight gain, let’s head over to the main question:

Do energy drinks make you gain weight?

Energy drinks can make you gain weight if taken in excess as they are primarily heavy in calories and sugar.

As we all know, energy drinks are processed and may include chemicals or substances that contribute to weight gain.

However, some brands are now promoting zero-calorie and sugar-free variations, which, if taken responsibly can help you with your diet. Here’s an article we have on zero-calorie energy drinks if you’re interested in knowing more about it.

With that said, zero-calorie energy drinks do not mean that they are healthier than those with sugar or calories.

Energy drinks that use artificial sweeteners to substitute for sugar can also lead to some risks, such as weight gain.

Artificial sweeteners such as sucralose and acesulfame potassium are 200-600 times sweeter than sugar; they may contribute to the risk of obesity despite having no caloric components.

In fact, artificial sweeteners tend to interfere with the body’s capacity to calculate calories, which means that sugar-free or any diet beverages may promote weight gain rather than weight loss.

Adopting a junk-food-free diet has several advantages, including weight loss.

Meals rich in calories, sugar, and fat are often found in junk food and processed foods. As a result, they’re considered a major contributor to the obesity epidemic and a driving force behind the onset of some chronic illnesses.

Adopting a junk-food-free diet has several advantages, including weight loss, stronger bones, improved digestion, a sharper memory, and a healthier heart.

Drinking More Water

According to certain studies, drinking water might help you burn calories.

Water can temporarily boost the body’s resting energy expenditure or the number of calories expended when at rest. Because the body expends energy, or calories, to heat up the water for digestion, drinking cold water may boost water’s calorie-burning effects.

Eat Foods That Are High in Fiber

Get Active

Exercise burns calories and reduces the risks of certain diseases.

While you’re burning calories, more exercise increases the number of calories your body utilizes for energy or “burns off.” When you burn calories via physical exercise while also reducing the number of calories you consume, you create a “calorie deficit.” This results in weight loss.

In addition, getting active can reduce the risk of certain diseases such as cancer, diabetes, and heart diseases.

30 minutes of exercise a day might be beneficial, but you should speak with your doctor or a trainer for a more tailored weight reduction program.

Adopt a Healthy Diet

You may also adopt a healthy lifestyle by consuming more whole meals and avoiding sugary foods. I’m not a health specialist, so speaking with your doctor about your diet may be beneficial and a more precise diet recommendation based on your body type.

How Often Should You Drink Energy Drinks?

If you decide to consume energy drinks, you can limit your intake to the recommended sugar limit by AHA. It is as follows:

Daily Limit (Sugar)

Drinking energy drinks on occasion has little to no influence on your weight or general health as long as you keep track of your intake and stick to the guidelines set by experts.

However, if you’re still looking for a boost or elevating your energy and mood, you can try sugar-free or no-calorie energy drinks. But like mentioned, these will unlikely cause you any weight gain as long as you consume the right dosage.


Energy drinks can make you fat if consumed in excess.

While energy drinks can be useful from time to time, the amount of caffeine and sugar in them might have negative consequences, such as weight gain.

You can always try the sugar-free and no-calorie variants if you’re seeking a boost while trying to avoid gaining any weight, but make sure you get the correct amount. They don’t help you lose weight or prevent you from gaining weight; they’re just ordinary energy boosters that can help you get through the day. However, they should only be taken on rare occasions or just when you need to.

Otherwise, get medical assistance from a dietitian or nutritionist to assist you with weight management and a customized diet that will boost your energy levels.
