Oh, you could've just ask someone in the supermarket, Hungarian people are usually very helpful :) Yes in English it's sour cream but I suppose it's completely different from the US ones. There are different types for those who are on diet, so you can choose a low fat version if you buy and I agree with the sugar thing. Sour cream is part of the Hungarian cuisine and is very healthy. :) (yoghurt is joghurt in Hungarian btw)

I can speak from experience that if you really want to diet try to minimize the sodium and sugars. Inside three weeks with almost no exercise I lost 21 pounds.

A diet? I guess that makes you hungry in Hungary

Even if it was yogurt, it doesn't seem like a healthy way to diet. You need proper varied meals, albeit lean ones.

Okay, just to say it because otherwise I'll wind up saying the same thing to a hundred different people, apparently, and will wind up more worried about people than I already am, here's a bit of a rant: Dieting by JUST "counting calories" or JUST "not eating carbs" or JUST "minimizing X and Y" IS NOT HEALTHY IN THE LONG RUN. Losing weight without any form of exercise is even worse because you WILL lose muscle tone and weight doing that. Before you even start a 'diet,' you need to figure out what your starting vitals and blood statistics like cholesterol, vitamins, and minerals are. Because if you have something that is low, and you cut back your general food intake you can not only make yourself very sick, but possibly cause permanent injury or even death to yourself. You need to know if you have any physical problems for the same reason- plus, if you do have health issues they can slow or even prevent weight loss. Plus, your doctor NEEDS to know what your starting statistics are so that they can stop you and tell you if you are being too aggressive in your weight loss and it is impacting your health. You ESPECIALLY need to make sure you don't have heart problems that you didn't know about- it's unfortunately common for people to decide to "be healthy" and jump into an exercise routine that's a over their level and causes them to have a heart attack because of a heart condition they didn't even know they had. If you want to lose weight, or even just improve your health, changing your lifestyle is inherently superior to doing diets, because once you stop a diet, your weight WILL go back up- and yoyo-ing your weight can cause heart problems, amongst other health issues- but when you change your way of living to be healthier, the weight tends to stay off and the benefits tend to stick around because you aren't doing what caused the weight and health issues to begin with. Lifestyle changes are also easier on your mental and emotional state- yes, there's some initial upheaval while you adapt, but once you do the changes become habit instead of being a thing you have to constantly consciously think of like a diet. Maybe I'm overreacting a little, but it worries the hell out of me when people endanger their health trying to improve it because they got some well meaning but hazardous advice. Your health is a precious thing- please don't endanger it by jumping from diet to diet or by diet if without exercising; it could take you years to recover from the damage caused by a few weeks, if recovery is even possible.

At least it's delicious?

To the one saying fat doesn't make you fat but sugar does. A gram of fat is equal to two grams of sugar or proteins in terms of energy/kcal (yes, proteins makes you just as "fat" as sugar). Stop reading some stupid magazines with "miracle diets" and learn it's all about calorie consumption compared to how many calories you burn.

OP I wonder how you didn't notice the difference, can't you taste it's not yoghurt?

That's double ydi. First one for being dumb enough to not being to tell cream from yougurt. Second for being dumb enough to think yogurt and fruits is dieting

According to google, tejföl is sour cream.
