Discover how water influences weight loss and whether it's wise to drink it during meals. Dietitian Lenny Versteegden provides clear, evidence-based answers.
Question: You often hear that drinking plenty of water is key to weight loss. Why is that? And should you avoid water with meals because it supposedly hampers digestion? A. van D., Pijnacker
Dietitian Lenny Versteegden: Water expands stomach volume, promoting a sense of fullness that naturally curbs appetite. However, ensure you're getting adequate nutrition—water provides no calories. Drinking too little food but too much water can lead to rebound hunger and cravings for sweets. Sipping water during meals is fine and won't hinder digestion, but moderation is key. Proper hydration supports kidney function for efficient waste elimination.
It's also essential for healthy bowel movements, which often suffer during weight loss due to reduced food and fluid intake. Prioritizing fluids helps counteract this.
Key facts on water: Extra water alone won't make you slim—that's a myth. Adults need about 1.5 liters daily, more with exercise, medications, or heat. Count tea, coffee, milk, and juices toward intake, but limit sugary juices, sodas, and alcohol during weight loss as they add calories and can increase hunger. Image: Getty Images
