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.
