Four litres of water a day puts stress on your body, dietitian warns

A dietitian warns that four litres of daily water is excessive and forces the body to work harder to excrete the surplus.

Justin Kestelman drinks four litres of water every day, thinking it supports his health. A dietitian reviewing his diet had a caution: that's too much.

Four litres is a lot of water. Excreting that excess can place extra stress on the body.

The amount you need depends on your size, activity level, climate and diet. Most healthy adults need far less than four litres.

Kestelman's diet does have genuine strengths: protein spread across the day, plenty of wholefood carbs, and oily fish for heart and brain health. His gap is vegetables.

Adding green leafy vegetables and salsa would boost fibre and phytonutrients without excess water.

Why it mattersMany people think more water is always better. It is not. Excess water can stress your body's system.

AustraliaIf you drink large amounts of water daily thinking it's healthy, you may be putting unnecessary stress on your body. Listen to thirst instead.
