Three main effects of drinking warm water

On his personal TikTok with more than 2 million followers, American doctor Kunal Sood shared that drinking warm water on an empty stomach has 3 main effects: improving digestion, supporting weight loss and promoting blood circulation.

According to Dr. Sood, "warm water helps dissolve foods that are normally difficult to digest. There are also studies showing that warm water can relieve constipation."

He cited research results published in the journal Gastroenterology Nursing showing that drinking water at 37 degrees Celsius has a "favorable effect on intestinal activity."

In addition to being good for digestion, warm water can also aid in weight loss. "Warm water can temporarily boost your body's metabolism. This is because your body will work to bring the warm water back to body temperature, and the slight increase in your metabolic rate will help you burn calories," says Dr. Sood.

Not only that, drinking warm water improves circulation and blood flow because it dilates your blood vessels.

However, he also noted: "It is important to be careful and ensure the water is not too hot to avoid the risk of burns."

Foods you should not eat when hungry

When feeling hungry, many people often choose whatever is available to satisfy their cravings. However, there are foods that are familiar but are not suitable to eat on an empty stomach, because they can make you hungry again quickly, cause digestive discomfort or even affect long-term health.

Beverages: Soft drinks and carbonated drinks contain a lot of sugar but do not make you feel full. In fact, the gas in soft drinks can cause bloating and stomach irritation.

Bottled fruit juice or fruit smoothies are also not good choices, because they often lack fiber, easily causing blood sugar to rise and then fall quickly, making the body tired and craving more food.

In addition, drinking coffee or tea on an empty stomach can stimulate acid secretion, causing heartburn, stomach pain, and even lead to ulcers if repeated frequently.

Food: Refined starches such as white bread, white pasta or cakes contain a lot of simple sugars, which are digested too quickly, making the feeling of fullness not last long.

Similarly, candy, cookies, and low-fiber snacks, while delicious, provide empty calories that do not adequately nourish the body. Some also contain additives such as MSG, which can stimulate the desire to eat more.

In addition, spicy, sour or acidic foods (such as chili peppers, citrus fruits) can easily irritate the stomach lining, leading to bloating and discomfort.
