Hmm, the user is asking which drink in the fridge has the lowest calories. Let me analyze the fridge contents and the search results carefully.

First, I need to identify all drink types visible in the fridge image. The search results provide calorie information for various beverages, which is crucial for comparison.
Looking at the search data:

• Regular sodas like Coca-Cola have about 43kcal per 100ml
• Sugary teas like Kangshi ice black tea (490ml bottle) contain ~165kcal
• Zero-calorie options are mentioned in the low-calorie drink article: Yuanqi Forest气泡水, Zero Coke, Kangshi无糖冰红茶, etc.

From the fridge image, I can see several categories:

1. Carbonated drinks (Bundaberg, Perrier)
2. Juices (orange juice bottles)
3. Sugary drinks (red-labeled bottles with Chinese characters)
4. Possibly zero-calorie options (VOSS water, green tea packets)

The key is distinguishing between sugary and zero-calorie drinks. The search results emphasize that "zero-sugar" labeled drinks like Zero Coke and Yuanqi Forest are low/zero calorie. Among visible options, the green tea packets (乌龙茶等) are likely low-calorie since unsweetened teas typically have minimal calories.
The VOSS water bottles might be plain or flavored - if flavored without sugar, they'd be near zero calories. But the image doesn't show clear labeling. The bottled juices clearly contain sugar based on packaging.

Therefore, the green tea packets and possibly the VOSS water (if unsweetened) are the safest bets for lowest calories. I should recommend these while acknowledging the uncertainty about some bottles.
