Frequently Asked Questions
Does water help you lose weight?
Water itself does not cause fat loss, but proper hydration supports metabolism, reduces appetite, and helps your body process stored fat. It also replaces caloric drinks.
How much water to drink for weight loss?
Aim for at least half your bodyweight in ounces daily. Some studies show benefits from drinking 8-16 oz before meals to reduce appetite.
Does cold water burn more calories?
Minimally. Your body expends a small amount of energy warming cold water to body temperature, but the effect is too small (about 8 calories per glass) to rely on for weight loss.
