OTL Fitness-Podcast 096 | Sind Zerogetränke gesundheitsschädlich?

This is a podcast episode from the Online Trainer Lizenz Podcast (OTL) addressing whether zero-/light beverages are harmful and what role alcohol plays for health and hydration. The speaker explains that artificial sweeteners in Zero products are not conclusively dangerous at normal intakes (long-term studies lacking) and that such drinks should not replace water but can supplement it. The episode summarizes DGE reference values for alcohol (≈10 g/day for women, ≈20 g/day for men), explains that alcohol is calorically dense (~7 kcal per gram), diuretic, and detrimental to hydration, performance and long-term health, and notes societal contexts where moderate occasional consumption may have limited harm. The podcast then introduces osmolarity and osmosis as determinants of fluid uptake, gives practical hydration tips (slightly cooled fluids are absorbed faster; during exercise ~200 ml every 15–20 minutes is recommended; higher sodium concentration can accelerate water uptake), and previews a deeper look at isotonic, hypotonic and hypertonic sports drinks in the next episode.

Questions this video answers

About 10 grams per day for a healthy woman and about 20 grams per day for a healthy man.

Approximately 7 kcal (per gram of alcohol).

Up to about 200 ml of slightly chilled fluid every 15–20 minutes.
