How much water should I drink each day?

7 April 2011 No Comment

Perhaps you have heard me say that drinking water helps you lose weight, or perhaps you have read something similar elsewhere. But when somebody says that to you, what does that even mean? How much water do we need to drink each day? do we need to drink more water on days we work out? How can we tell if we have had enough water?

© Microsoft ImagesWhen I first looked up how much water I should drink a day I found this article by After describing WHY we should drink water (another article for another day), concludes that we should drink half our weight in ounces. So if you weigh 116 pounds you need 58 ounces of water a day – or roughly just over 7 cups of water. This is how I calculate my daily water intake.

Dr. Sharon E. Griffin confirms these recommendations in her post using the formula: 0.5 ounces x Body Weight in Pounds = Daily Fluid Requirement in ounces.

She continues to say that another way to measure your daily water intake is to use the formula: 0.034 ounces x Daily Caloric Intake = Daily Fluid Requirement in ounces.

Dr. Griffin further concludes that regardless of which way you calculate it, “as you calculate out what your daily fluid requirements are, you’ll probably realize that it is close to that common recommendation of 8 – 12 cups per day.”

Kraft Recipes does a really good job of summarizing the requirements from the Institute of Medicine on their website. Below are the Institute of Medicine’s daily water recommendations based on age and sex.

I stick with drinking half my weight in water – the 9 cups of water suggested here is more than half my weight in water.

But regardless of what you decide – here are a few things to keep in mind

  • If you are thirsty, you are already deydrated
  • Water consumption needs to include the water you are drinking in coffee, tea and koolaid and other beverages   – but plain water doesnt come with the sugar and calories you find in other drinks.
  • Water can also be found in water dense foods like iceberg lettuce and watermelon – and these all count towards your total daily consumption
  • THERE IS SUCH THING AS TOO MUCH WATER – be aware of your body. and be careful.

On that note, my first glass of water everyday is in my shakeology. Nutrient dense AND full of water 🙂 I am making sure to start out my day right! Are you? How much water do YOU drink everyday?
