A Glass of Water on an Empty Stomach for Dieting... Is It Effective?

A glass of water on an empty stomach.

You have probably heard many times that drinking a glass of water on an empty stomach is good for dieting and detoxing.

However, research results show that these benefits may be somewhat exaggerated.

According to literature published in the international journal JAMA Network Open in 2024, only 10 out of 18 randomized clinical trials showed positive results, while the remaining 8 showed no such effect.

There is also a claim that lukewarm water is better.

A 2014 study published in Acta Physiologica found that energy expenditure increased when drinking cold water, but there was no significant change with 37°C (99°F) water.

However, drinking enough water can help manage constipation.

It was also found to play an important role in total daily water intake.

Keep in mind that water itself is good for you.
