German YouTube podcast episode (OTL Fitness-Podcast 096) discussing health aspects of Zero/Light (sugar-free) beverages and alcohol, plus practical hydration and basic sports-drink physiology. Key points: Zero drinks are nearly calorie-free and useful as occasional complements to water but long-term safety of sweeteners is not fully settled due to lacking long-term studies; alcohol has no health benefits, is dehydrating, caloric (~7 kcal/g alcohol), can impair sport and muscle growth, and carries disease/addiction risks though small occasional intake near DGE reference values (≈10 g/day for women, ≈20 g/day for men) is viewed as acceptable; osmolarity and the three sports-drink classes (isotonic, hypotonic, hypertonic) affect fluid uptake, and lightly chilled fluids (~200 ml every 15–20 minutes) improve hydration during exercise. The episode previews a follow-up that will examine isotonics and other drink types in more detail.
