Staying Hydrated on a Low Calorie or Low Carb Diet

Cut carbs or calories and your body starts handling water differently. You may drink the same amount as before and still feel flat, headachy or tired. This page explains why, and helps you decide between electrolyte powders, gummies and flavoured diet drinks, plus fibre drinks for regularity.

Electrolyte powders for everyday sipping

Legion Hydrate Electrolyte Powder - 20 Packets - Fruit Punch

$29.99

Legion Hydrate Electrolyte Powder - 20 Packets - Lemon Lime

$29.99

Legion Hydrate Electrolyte Powder - 20 Packets - Watermelon

$29.99

A powder in a packet is the most flexible option. You stir it into a bottle of water and sip through the day. Legion Hydrate is described as having no sugar and no artificial additives, and the retailer says many people on GLP-1 plans find it useful. It suits anyone who wants a proper drink in a bottle, especially at the gym or on a warm day. Check the label for sodium per packet before you pick a flavour, since that is the number that matters most here.

Gummies for travel and tight spaces

Plant People Wonder Hydrate Electrolyte Gummies - Lychee - 10ct

$9.95

Gummies trade volume for convenience. Plant People Wonder Hydrate comes as 10 lychee gummies in a resealable travel pouch, and they are described as vegan and sugar-free. They suit a handbag, a desk drawer or a flight, where mixing a drink is a nuisance. They do not add much water by themselves, so keep sipping alongside them. They are a good backup rather than a full replacement for a powder.

Flavoured diet drinks that add protein

Proti-thin Fruit Drink - Pink Lemonade - 7/box

$16.95

Proti-thin Fruit Drink - Lemon - 7/box

$16.95

ProtiDiet Liquid Concentrate - Cool Raspberry - 7/Box

$12.95

If plain water bores you, a flavoured drink can help you drink more. Proti-Thin fruit drinks are described as light, fruity and easy to drink any time, and they bring protein along with the flavour. ProtiDiet Liquid Concentrate is mixed with cold water and described as a way to add protein without the thickness of a shake. These suit people who want one drink to do two jobs. They are not electrolyte products, so compare the label for sugar and sodium per serving against a powder before you treat them as one.

Fibre drinks and regularity

Weight Loss Systems Fiber Drink - Iced Tea with Lemon - 10/Box

$16.95

Weight Loss Systems Fiber Drink - Mixed Fruit - 10/Box

$16.95

Eating less food often means less fibre, and regularity can slip. Fibre also needs fluid to do its job, which is why it belongs on a hydration page. The Weight Loss Systems Fiber Drinks give 5 grams of soluble fibre per serving, at only 15 calories, in Iced Tea with Lemon or Mixed Fruit. They suit people who find a cold drink easier than a supplement tablet. Have one with a full glass of water on the side.

Why fluid needs change when you eat less

Food carries a lot of water, and so do many carb-rich foods. Eat less of them and you take in less fluid without noticing. Lower carb eating also tends to mean less processed food, which often means less salt. So you may need to drink more on purpose and pay closer attention to sodium and other minerals. Plain water covers the first part. It does not always cover the second.

How to choose

  • Start with the job. Replacing lost minerals points to a powder or gummies. Adding protein points to a Proti-Thin or ProtiDiet drink. Regularity points to a fibre drink.
  • Read sugar and sodium per serving. This is the quickest way to compare a powder, a gummy and a flavoured drink fairly.
  • Think about where you will use it. Gummies travel well. Powders need a bottle. Boxed drinks suit a routine at home or work.
  • Look at the pack size. Legion Hydrate has 20 packets, the gummy pouch has 10, and the fruit drinks come in boxes of 7 or 10.
  • Pick a flavour you will actually finish. A drink you like is a drink you will keep having.

Questions people ask

Do I need electrolytes if I just drink more water?

Not always. But on a low carb or low calorie plan you may take in less sodium, so some people add an electrolyte product. Check the label and follow the directions.

Are gummies as good as powders?

They do different things. Gummies are easy to carry. Powders turn into a drink, so they help you take in fluid too.

Can a protein fruit drink replace an electrolyte powder?

The descriptions present them as protein drinks, not electrolyte products. Compare the labels to see what each one gives you.

When should I have a fibre drink?

Follow the directions on the box, and have it with plenty of water. A regular time each day makes it easy to remember.
