JAKARTA - A Harvard-trained gastroenterologist shared an interesting finding that is to stop consuming added sugar for two weeks. By doing this alone can bring real changes to the body. Not through extreme diets or excessive detoxification, but rather small changes that happen slowly in the body.

Through a post on social media, Dr. Saurabh Sethi, a gastroenterologist and hepatologist who practices in the San Francisco area, explained that many people underestimate the impact of sugar on health. In fact, without realizing it, sugar affects appetite, insulin function, and liver health.

Dr. Sethi does not recommend a strict diet or an instant weight loss target. The focus is instead on how added sugar works silently in the body.

"Sugar is not just a calorie booster. Sugar triggers excessive eating, messes with insulin signals and increases fat accumulation in the liver, often without obvious symptoms," said Dr. Sethi, quoted from The Economic Times website.

Therefore, he recommends that his patients try to stop consuming added sugar for 14 days as a simple but meaningful step.

In the first few days, many people feel unwell. From sweet cravings, headaches, fatigue, irritability, to difficulty focusing. However, according to Dr. Sethi, this condition is often misinterpreted as 'sugar sickness'.

"This is not a symptom of substance withdrawal," he explained.

What is actually happening is that the brain is readjusting the reward system after getting used to getting excess sugar intake.

After going through the initial phase, the body begins to show signs of adjustment. Energy feels more stable, the desire to snack is reduced, the stomach is not easily bloated, and the feeling of being tired in the afternoon begins to disappear.

Towards the end of the two weeks, many patients reported sleeping better, a clearer sense of hunger (not just snacking), and a much reduced impulse to eat. In some people, fasting blood sugar levels began to improve, although weight did not necessarily come down immediately.

"These changes are often not visible on the scales, but the body's metabolism has actually started to shift in a healthier direction," said Dr. Sethi.

Stopping the consumption of added sugar for 14 days provides several important benefits, such as a more controlled insulin spike, reduced liver workload, decreased fluid retention, and a sense of taste that is more sensitive to the natural taste of food. Dr. Sethi emphasizes that this is not a diet program to lose weight, but a metabolic reset.

He also clarified that this method is not a keto diet, not zero carbohydrates, not long fasting, and does not prohibit eating fruit. The only thing to avoid is added sugar, which is often hidden in everyday foods.

Many products that look healthy actually contain high sugar. Yogurt flavors, breakfast cereals, energy bars, sauces, salad dressings, cakes, packaged juices, and even sweet alcoholic beverages are often hidden sources of sugar.

According to Dr. Sethi, food labels can be misleading. The words 'healthy' or 'low fat' do not always mean low sugar.

Based on his experience at the clinic, Dr. Sethi said a short break from sugar is very helpful for people who often feel hungry, easily bloated, have fatty liver, insulin resistance, low energy, or poor sleep quality.

This change is not just a theory. He claims to see the results directly on many patients.

As a doctor with dual certification in gastroenterology and hepatology, as well as educational backgrounds from AIIMS, Harvard, and Stanford, Dr. Sethi's views add an important message.

"Small changes over two weeks can open our eyes to how much sugar affects our daily health."
