How We Calculated This

What Counts Toward Your Water Goal?

โœ… These Count

  • Plain water (still or sparkling)
  • Zero / low-calorie flavored water
  • Black coffee
  • Unsweetened tea
  • Diet drinks (0 cal)

โŒ Don't Count These

  • Milk (it's a calorie source)
  • Juice or regular soda
  • Protein shakes & smoothies
  • Sweetened coffee drinks
  • Alcohol (dehydrates you)
Remember: These are guidelines, not exact science. Listen to your body. A good check is your urine color โ€” aim for pale straw. If it's dark yellow, drink more. If you're on a high-protein diet, your kidneys are working harder to process nitrogen byproducts, so adequate water is especially important to keep them healthy.

Pro Tip: Front-load your water intake early in the day. Carry a large bottle and sip consistently rather than chugging large amounts at once.
