How Much Water Should You Drink on the Dukan Diet?

As a rough rule of thumb you should be looking to drink 1.5 to 2 liters of fluid per day but each person’s requirements vary depending on their circumstances.

Weight – the more you weigh the more fluid you need

Gender – men need more water than women.

Where you live – the warmer the climate the more water you’ll require.

Breastfeeding – requires a greater fluid intake but you should not be following the Dukan Diet if breast feeding.

Certain Health Conditions – mean a higher intake of fluids is needed such as diabetes or cystic fibrosis.

Exercise – the higher the level of activity the higher the water intake should be.



 Ensuring an adequate intake of fluids each day is very important for reasons I’ll explain later in the post but not many people know that it is possible to drink too much.

Your body can process a large amount of fluids but excessive water in a short space of time can cause a condition known as water intoxication which produces symptoms from confusion and headaches to coma and seizures, milder symptoms include bloating, weight gain, vomiting and nausea.

 So why is water important

  • Our bodies are mostly made from water containing on average between 55% and 75%.
  • Every organ and tissue in our body contains water
    • Blood has 83%
    • Muscles 73%
    • Body fat 25%
    • Bones 22%
  • We need water to
    • eliminate waste, keeping us regular and preventing the formation of kidney stones
    • maintain our body temperature
    • keep our skin hydrated and supple
    • cushion our joints
    • transport nutrients around our body
    • help our heart – when our fluid levels are where they should be our heart doesn’t have to work as hard to pump blood throughout our body.
    • boost our energy levels – being dehydrated makes us tired and lethargic
    • exercise optimally – drinking waters prevents cramps and it allows you to exercise for longer.  You should take a small amount of fluid every 20minutes or so when exercising.
Water can also be an aid to help us lose weight
  • It can help reduce our caloric intake – drinking water before a meal reduces the amount that you eat.
  • Replacing other drinks with calorie free water reduces your calorie intake.
  • It can increase your metabolic rate especially if drunk very cold as your body has to expend energy warming the water up.

    I was wondering if drinking too much water can work against you.

    I lost 4 pounds in attack phase and in day 6 I gained 4 lbs overnight.

    I have been following the diet to the T and exercising lots.

    Thanks,

      Hi Pat

      If you are following the diet to a T try not to worry as water retention can make a big difference to weight loss. Certainly drinking too much water can cause this but there are also other causes such as monthly hormone cycle or salt in foods. The other most common reason for weight gain is constipation.

      Kind regards

    Thank you for the swift reply Amber!

    I was going to ask him to cut down to 3 litres a day, and just see how it goes for a week. It’s such a dangerous time when eating so much protein. If he really struggles I’ll send him to the GP.

    Would you advise I try not to exceed my usual 2 litres a day?

      Hi Sarah

      I think the 2 litres is going to be about right:)

      Best wishes

    Hi,

    My boyfriend and I just started this diet yesterday. I am obese with BMI ~30 and he is overweight at ~26. We are both young and in our 20s. Before the diet I would drink 2 litres a day of tap water (which is very soft in our area) and he would drink 4-6 litres. Yesterday I took in 3.5 litres because I’d read about flushing out the uric acid, unaware I could have ‘too much’ water.

    Apart from walking, neither of us exercise anymore, and we live in northern England so it isn’t exactly hot. Is 3.5 litres too much?And is he in danger if he drinks even more?
