Can Drinking More Water Really Help You Lose Weight?
Research suggests that simply increasing your daily water intake may offer a range of health benefits, including weight management, improvement in metabolic conditions, and even fewer urinary tract infections.
This study, published in JAMA Network Open, comes at a time when many are looking for simple, low-risk ways to improve their health. It reviewed 18 randomized clinical trials, encompassing a range of durations from just 4 days to 5 years.
The results were promising. Three studies showed that drinking two cups of water before meals could significantly boost weight loss in adults, with some participants losing up to 100% more weight than those who didn’t alter their water intake. Researchers theorize that this effect might stem from a feeling of fullness before eating, potentially leading to reduced food consumption.
Beyond weight management, the trials added to a growing body of evidence suggesting that staying properly hydrated can be beneficial for other health issues. Diabetes patients saw significantly reduced fasting blood glucose levels when they drank water before meals. While the benefit is not fully understood, it’s thought that water intake may help regulate blood sugar by aiding the digestive process, making it easier for the body to process carbohydrates.
Women who increased their daily water intake by 1,500 milliliters experienced fewer urinary tract infections. These findings suggest that increased water intake can improve urinary tract health, potentially helping to flush out bacteria, reducing the likelihood of infection.
Though a lack of a one size fits all approach for water intake is emphasized.
“We know that dehydration is detrimental, particularly in someone with a history of kidney stones or urinary infections,” said senior and corresponding author Benjamin Breyer, MD, MAS, the Taube Family Distinguished Professor and chair of the University of California-San Francisco’s Department of Urology.

## Can Drinking More Water Really Help You Lose Weight?
**Host:** Welcome back to the show! We’re talking about the trendy topic of weight loss today, and our guest is Dr. [Guest Name], a registered dietician with expertise in nutrition. Dr. [Guest Name], thanks for joining us.
**Dr. [Guest Name]:** My pleasure.
**Host:** We’re all bombarded with fad diets and complicated workout programs promising quick results. This new study published in *JAMA Network Open* is making headlines because it suggests something as simple as drinking more water could be key to weight management. What are your thoughts on this?
**Dr. [Guest Name]:** It’s certainly a fascinating study. The researchers analyzed 18 clinical trials and found that drinking two cups of water before meals could significantly boost weight loss in adults. Some participants lost up to 100% more weight compared to those who didn’t change their water intake.
**Host:** That’s pretty impressive! Can you explain how drinking water before meals might lead to weight loss?
**Dr. [Guest Name]:** Researchers believe it might be due to a feeling of fullness. When you drink water before eating, it takes up space in your stomach, signaling to your brain that you’re already partially full. This could lead to eating less during your meal and ultimately consuming fewer calories [1].
**Host:** That makes sense. Are there any recommended daily water intake guidelines for weight loss?
**Dr. [Guest Name]:** The study doesn’t specify a precise amount, but generally speaking, aiming for the daily recommended intake is a good starting point. According to Verywell Health, the dietary reference intake (DRI) of water for men is 3.7 liters per day, and 2.7 liters for women. [1]
**Host:** Of course, this shouldn’t replace a healthy diet and regular exercise, but it seems like a simple, low-risk way to potentially support weight loss goals. Dr. [Guest Name], thank you so much for sharing your insights.
