  • Celsius drinks are not a substitute for water, and you should still drink plenty of fluids to stay hydrated and prevent keto flu symptoms.

Whether you drink it or not, you should always choose Celsius drinks that are sugar-free and have natural flavors. Because:

Do not store Celsius drinks in the freezer, as freezing can damage the container and cause the drink to become flat.

Finally, remember, Celsius drinks are a convenient way to boost your energy and metabolism, but they are not a magic bullet for weight loss or health.

You should still follow a balanced keto diet and exercise regularly to achieve your goals.
