The water intake from food and other sources was found to be higher in females than in males, which helped with lower obesity levels.

Rena, a blogger, increased her daily water intake and shared the results on her personal blog: “I find myself snacking less when I actually drink enough water (i).” She adds, “I remember hearing somewhere that a good rule of thumb to know how much you should be drinking is to take your body weight, divide it in half, and drink that many ounces.”

Always start exercising only when you are hydrated. It is recommended to drink 400 mL to 600 mL of fluid 2 hours before beginning exercise (8).

You also have to keep the weather of a particular area in mind. Dry or humid areas can cause more water loss through sweating. This means you must keep sipping on at least 150-200 mL of water every 15 minutes if you sweat a lot.

So, on an average, consume 4-5 liters (women) or 6-7 liters (men) of water for weight loss (if you participate in vigorous workouts regularly and tend to sweat a lot).
