Lemon Water & Weight Loss: Does It Work?

TikTok is known for its trends, with users trying various things for their health goals, from “oatzempic” to okra water and seed cycling.

The latest trend is hot lemon water, which influencers claim can boost metabolism, reduce bloating, and burn calories if consumed before bed.

However, according to registered dietitian Denise Hernandez, this claim is not true.

Hernandez explains that lemon water is traditionally used for cold and flu relief, but there’s no scientific evidence that it contributes to weight loss.

While lemon water may not aid weight loss, it could offer other benefits.

Lemons are a good source of antioxidants, like vitamin C and polyphenols. These antioxidants protect cells from damage. Vitamin C helps the body produce collagen, a protein that supports skin, muscle, bones, and connective tissue. It also helps the body absorb iron from food and may boost the immune system. Polyphenols, another antioxidant found in lemons, may help alleviate fatigue and lower cholesterol and blood pressure.

Besides these benefits, lemon water might help with allergies and even alleviate cold and flu symptoms like a sore throat.

Lemon water, whether hot or cold, can help you stay hydrated. According to the NIH, 75% of people don’t drink enough water. Drinking enough water is important for temperature control, cognitive performance, and gastrointestinal function.

Be careful not to consume too much lemon in your daily water intake.

Mercer warns that excessive lemon water can worsen acid reflux, increase tooth decay, trigger canker sores, and interact with certain medications.

Don't expect a magical weight loss drink, as Mercer emphasizes that "it doesn't exist." Weight loss and management require a consistent and holistic approach.

However, food-logging is scientifically proven to support weight loss over time. Research shows that individuals who track their food are more likely to achieve their weight loss goals.
