Why an Energy Drink Is Sometimes Better Than Fruit Juice

I was maybe sixteen when I first tried an energy drink. Not at a party, not during a late gaming night. Just an ordinary day at school, a friend brought a can after we played football, I never really played football but somehow ended up there that day. I tried it. It was fine. And that was it, because for the next three years I didn’t touch one. Only later, already a bit older, I just bought one for myself one day. No occasion, no reason. Just felt like trying it again. And that’s when it became part of my gaming routine.

For the next few years energy drinks showed up mainly during evening gaming sessions. Not every day, not several at once, usually one, and maybe once or twice in my entire life did I drink two in a single day. I drank the well-known brands, in half-litre cans. Nobody recommended them to me, nobody warned me off them. I just drank them.

Today I’m twenty-seven, I train regularly, I watch what I eat, and I’ve recently gone back to the occasional energy drink. I’m not going to justify that. What I do want to say is something not many people say out loud: a sugar-free energy drink is sometimes a better choice than a glass of store-bought fruit juice. I know that sounds provocative. That’s exactly why I’m writing this.

How the Habit Started and How I Got Out of It

The problems started appearing somewhere around age twenty-three or twenty-four. I don’t remember the exact moment, but I remember the feeling: shaky hands after drinking an energy drink, worse sleep, a general restlessness I hadn’t previously connected to caffeine or sugar. Several things were probably piling up at once. I was finishing a three-year vocational training programme in Germany, I had exams, I had stress. But my body was clearly signalling that something was off.

I decided to stop. And not just with energy drinks. I cut all sugary drinks at the same time. New Year, one clear decision: from now on only water, tea, coffee. And I stuck to it for nearly two years.

Two Months to Feel the Difference

The first weeks were ordinary. No dramatic changes, no sudden “I feel like a new person.” It was only after roughly two months that I started noticing things I hadn’t previously connected to drinks.

First, the sugar cravings. They disappeared in a way I didn’t expect. Not immediately, but one day I simply realised I had no urge for chocolate bars or sweets. Things I used to eat without thinking were suddenly too sweet for me. It wasn’t a resolution or a special diet, they just stopped appealing to me.

Sleep improved. Steadily and noticeably, though not overnight. Fewer moments of waking up in the middle of the night for no reason. I work rotating shifts and often start at 3:50 in the morning, so sleep quality is not an abstract concept for me, it’s a matter of functioning through the whole day. I also noticed the afternoon energy dips happening less often. A coffee or a short twenty-minute nap, the kind that actually works, was more than enough.

This all makes sense in light of the research. A meta-analysis published in BMJ, covering over thirty randomised controlled trials and thirty-eight cohort studies, found that increased sugar intake, particularly from sugar-sweetened beverages, was associated with weight gain in populations eating without strict calorie control, and that the risk of overweight was 55% higher among those with the highest intake of sugary drinks compared to those with the lowest (Te Morenga et al., 2013, BMJ, DOI: 10.1136/bmj.e7492). I didn’t plan this as an experiment, but my body ran it for me.

Why I Came Back and Don’t Regret It

After nearly two years without energy drinks, I started reaching for one occasionally. Not because I’d fallen back into some habit, not because anything was wrong. One day I simply read the ingredients of a sugar-free version carefully and concluded that nothing dramatic was going on. Caffeine, B vitamins, zero sugar.

Now I drink energy drinks irregularly. Sometimes one a week, sometimes two, then three weeks of nothing because I simply don’t feel like it. I don’t treat them as something forbidden, so I have no particular drive to focus on them in either direction. About one a week on average, but that’s a result, not a plan.

And this brings me to the point.

Why Fruit Juice Is More Misleading Than an Energy Drink

When someone pulls a carton of orange juice out of the fridge and says “I’m having something healthy,” I feel a quiet discomfort. I don’t mean that unkindly, I thought the same thing for years. But store-bought fruit juice is largely sugar in liquid form. Not vitamins, not fibre, not the same as eating a piece of fruit. In a whole fruit you have fibre, which slows sugar absorption and regulates the glycaemic response. In juice you don’t.

This isn’t my personal theory. The same BMJ analysis that covered sugary drinks also found that regular consumption of fruit juice was associated with a 7% higher risk of type 2 diabetes per daily serving, and the authors explicitly state that both artificially sweetened beverages and fruit juice are unlikely to be healthy alternatives to sugar-sweetened beverages for the prevention of type 2 diabetes (Imamura et al., 2015, BMJ, DOI: 10.1136/bmj.h3576). This is not an article about energy drinks. This is an article about juice.

Meanwhile, a sugar-free energy drink has a clear label and a clear ingredient list. And, perhaps more importantly, nobody walks out of a shop with a can thinking “right, that’s my five portions of fruit and vegetables sorted.” That is exactly what tends to happen with juice. You drink it, you feel like you’ve done something good for yourself, and the rest of the day stays exactly the same, because you already got your fruit in.

When I drink an energy drink, I know I’ve had something extra and I factor that into the rest of my day. That is the key difference for me: a conscious decision versus the illusion of a healthy choice.

I’m not saying energy drinks are healthy. I’m saying store-bought fruit juice isn’t either, and a lot of people treat it like a dietary supplement.

What Two Years Without Taught Me

I don’t regret that break. I learned a few things that now feel obvious but weren’t at the time.

Sugar in drinks works differently to sugar in food. You don’t feel full from it, you raise your blood glucose and shortly after you want something sweet again. Cutting sugary drinks is one of the easier steps for stabilising sugar cravings throughout the day, without any special diet and without counting calories in every meal.

Caffeine without sugar works more predictably for me. A black coffee or an occasional sugar-free energy drink gives me a clean, steady effect. Caffeine paired with a large amount of sugar used to give me that sugar rush followed by a crash, and that was exactly what I felt as shaky hands and irritability. Now when I want more energy I reach for coffee or, less often, a sugar-free energy drink. Not a can with twenty-seven grams of sugar.

It’s also not about avoiding something for the rest of your life. It’s about knowing what you’re drinking and why. When I went back to the occasional energy drink, it was a conscious decision based on reading the label, not a reflex from old habit. And that difference, between habit and choice, matters more to me than the product itself.

Now when I stand in front of the fridge at a petrol station and see half a litre of “100% fruit juice” next to a zero sugar can, I know what I pick. And I know exactly why.
