JAKARTA - Recently, social media has been busy with the trend of drinking lemon coffee, a mixture of black coffee and lemon juice which is claimed to help lose weight, burn fat, and increase energy.

This trend is widely known through the hashtag #coffeelemonchallenge on TikTok and has been tried by many people who are curious about its benefits. However, experts warn that lemon coffee is not always healthy and can even cause some unwanted side effects.

Supporters of this trend argue that the mixture of caffeine from coffee and vitamin C from lemon can have a double effect, namely reviving energy while helping the body detox.

Some netizens claim they managed to lose weight after regularly drinking lemon coffee every morning. But nutritionists insist there is no scientific evidence to support the claim.

Reporting from the Tasting Table page on Saturday, October 11, 2025, weight loss occurs due to a calorie deficit, not due to a combination of coffee and lemon. He added that the effects felt by some people most likely came from caffeine which could suppress appetite for a while, not from a mixture with lemon.

Coffee and lemon both have a high level of acidity. The average coffee has a pH of around 4'5, while lemon is much more acidic with pH 2'3.

According to the Tasting Table report, adding lemon into coffee can change the balance of the natural acid of the drink. Lemon can make coffee taste too sharp and cause digestive disorders.

For those who have a sensitive stomach or stomach acid disorder (GERD), a mixture of coffee and lemon can actually worsen the symptoms. The burning feeling in the chest (heartburn), bloating stomach, and nausea can appear after consuming it.

Caffeine has stimulated stomach acid enough. So adding lemon actually worsened his condition.

In addition, for those who like to add milk to coffee, lemon mixtures can cause milk to clot due to acidic reactions to kaseine protein in milk. The result is that the drink looks clotming and unfit to drink. Although there are many warnings, it does not mean that coffee and lemon cannot be consumed at all.

Lemon is rich in vitamin C and antioxidants. While coffee also contains compounds such as polyphenols that are good for the body if consumed wisely. The benefits of both remain more optimal if consumed separately.

You can still enjoy a glass of dark coffee in the morning and drink warm lemon water at different times. Both can support a healthy lifestyle, but not in the same cup.

If you're curious about lemon freshness but don't want to experiment extremes, try lemonade coffee drinks like Thunderbolt, which come from lemonade mixtures andiri. In this drink, lemon levels are more dominant, while coffee only serves as a flavor balancer.

However, if you want to maintain the health of your stomach and digestive system, it is better to continue to enjoy coffee and lemon separately. Social media trends can not always be used as a reference for a healthy lifestyle.
