Garcinia diet stick coffee with 750mg a pack: Heorissok Dark Americano
In short
Heorissok Dark Americano is a Korean stick-type diet coffee that packs 750mg of garcinia cambogia extract, the full daily intake, into one sachet. Drinking 1 to 2 packs a day for a week — on the way to an internship and on a camping morning — Heorissok dissolved fully in cold water and tasted clean like cold brew, with no sourness or harsh bitterness. For dieters who can't give up daily coffee, Heorissok Dark Americano is worth trying as a substitute.

I'd been enjoying my time off pretty well, but then I ended up doing an internship through a government program called Miraenaeil Chaeumjeol. Getting back to commuting after so long threw me off completely and left me exhausted. So naturally, the thing I reach for every single day is a nice cold cup of coffee. That's how I stumbled onto a diet Americano and gave it a try — and it's so good I really had to tell you all about it!! haha


What is Heorissok Dark Americano diet coffee?
📍This is Heorissok Dark Americano. The reason I'm recommending this instead of your average stick coffee brand is that it's actually made to support your diet haha
📍It contains garcinia cambogia extract, which helps reduce body fat by suppressing the conversion of carbs into fat — so it takes a bit of the guilt off carb intake. The daily recommended intake of garcinia cambogia extract is 750mg, and that's all packed into a single stick. Garcinia has been a famous diet supplement ingredient for a long time now.

Easy-cut sticks that fit a commute tumbler
The tumbler I carry to work every day and Heorissok diet coffee basically come as a set haha. I share it with a fellow intern too, so we always drink it together.


It's easy to tear open with the easy-cut design, and the powder is so fine it dissolves well even in cold water!

How does Heorissok taste? Water amount and bitterness
📍The basic recommended water amount is 250-300ml, but I prefer a weaker Americano so I tend to add more water. Even so, the flavor still comes through rich enough. There's none of that typical Americano sourness or bitterness — it just tastes clean, like cold brew.
The coffee aroma is fragrant without being overwhelming, so it's easy to get into even if you're not great with bitter coffee. I once tried a diet coffee called Bulletproof Coffee and it was a bit greasy and not really my style, so I was a little worried this one might be similar — but I've been drinking it happily without any issues.

I just mix it into my water bottle on the way to work, and I always keep two or three packs in my bag. You never know when you'll want one, right? lol


One pack on a camping morning, with salt bread
Even after a full-on eating party at the campsite, I had bread and Heorissok diet coffee for breakfast. Dieting isn't about dropping weight all at once — it's about consistently managing your diet and lifestyle habits, but sometimes it's hard to stick to that ㅜ. In those moments, this kind of thing can help mentally too, so I'm planning to use this convenient product as part of my diet routine!
It dissolved well even in ice water, so I started the morning off with a refreshing cup of coffee. My friends said it was delicious and took a few packs home lol. It goes really well with salt bread too — since it's the dark Americano flavor, it actually paired really well with heavier, more indulgent bread. (Not saying you should go eat indulgent bread all the time though haha)

It's only been a week since I bought it, but since I've been drinking 1-2 packs a day without fail, half of it is already gone ㅜㅜㅠ I've been enjoying it so much that I'd definitely repurchase once I finish the box!
Who should try Heorissok Dark Americano?
- People who are dieting
- People who can't live without a daily cup of coffee
- People worried about their carb intake
🚨Conclusion🚨 I've been combining exercise and diet, and swapped my daily coffee for Heorissok diet coffee. There are probably several factors at play, but even after eating a ton at the campsite, my weight barely changed and stayed pretty stable, and I've been losing a little bit day by day, so it seems to actually be pretty effective! Of course, relying too much on any one product isn't a good idea, you all know that right?? haha

Here's a shot of my little blog troublemaker too haha. Grown up so much, right??
