I found that kombucha is an excellent, really low-calorie alternative to sugary drinks. Actually, to sugar in general. I have a sweet tooth and I have difficulty managing it some times.
Kombucha is filling and most times one can is enough to make the cravings stop completely. I suspect it's a combination of the slightly sweet taste with the good gut bacteria.
You unfortunately need to be fairly careful about the kombucha you select. Many of the big/common ones sold at grocery store chains oftentimes anywhere from 10-20mg sugar for a 12/14oz bottle (I've seen them with more than that too!). Better than soda but worse than many smaller brands or even local kombucha you might find at restaurants around town or a farmers market. My favorite kombuchas hover around 5mg per 12oz serving which is perfect.
I'm in the UK. I always check the nutritional information labels. So far I haven't found a single brand of kombucha that has more than about 20kcal/100ml. Most are around 1-5kcal.
For example, this Lo Bros [0] flavour has <0.5g of sugar, and only 3kcal/100ml.
Isn't kombucha basically the same as soda? High acidity (which is bad for dental health), which is offset with sugar (which coincidentally is also bad for dental health).
(At least, as a water drinker, they both taste equally strong)
