Song Seung-heon went on a diet to film an exposure scene… He survived by eating only ‘this’ for 3 weeks?

Actor Song Seung-heon said he went on an extreme diet for the movie.

Song Seung-heon and Park Ji-hyun, the main actors of the movie ‘Hidden Face’, appeared on SBS Power FM’s ‘Kim Young-cheol’s Power FM’, which aired on the 12th.

On this day, DJ Kim Young-cheol read a listener’s comment saying, “Song Seung-heon. I heard that you survived for three weeks by rinsing your mouth with water and eating nuts for the ‘Hidden Face’ bed and bathtub scenes. What did you eat as much as you wanted for your first meal after filming?”

Song Seung-heon responded, “I’m not usually good at dieting, but at that time, I think I only ate nuts and water. After filming, I ate tteokbokki. The director asked me what I wanted to eat at that time and prepared it for me.”

When asked if she ate with actress Park Ji-hyun, Park Ji-hyun expressed her regret, saying, “But I guess I didn’t finish the day Song Seung-heon’s exposure scene ended. So I couldn’t eat.”

Nuts are rich in dietary fiber and help prevent overeating.

Nuts, the food that Song Seung-heon chose for his diet, are rich in healthy unsaturated fats, plant proteins, and dietary fiber, which are beneficial to blood vessel health and are also effective in skin health and anti-aging. It gives you a feeling of fullness and prevents overeating, but it contains fat, which can cause you to gain weight if you overeat.

However, according to a study by a research team from the University of South Australia published in the international academic journal Nutrition Research Reviews, adding an appropriate amount of nuts to the diet can increase the weight loss effect.

The research team provided 676 overweight or obese adults with a calorie-restricted diet of 240 to 1,000 kcal per day. However, one group was given an additional 42 to 84 g of nuts, such as almonds, peanuts, pistachios, and walnuts, every day, while the rest were allowed to eat only the prescribed diet.

As a result of the study, which was conducted over a period of at least 4 weeks and as many as 52 weeks, it was found that the group that consumed nuts as part of their diet every day lost about 1.4 to 7.4 kg more weight than the group that consumed only the basic diet. However, we did not find any additional benefits for body composition and blood sugar control.

“Nuts are rich in healthy unsaturated fats, plant-based proteins and dietary fiber, which play a role in increasing satiety and reducing excessive calorie intake,” said Professor Allison M. Coats, lead researcher of the study. “Furthermore, they further support cardiovascular and metabolic health, gut health and cognitive function. “It can contribute to improvement,” he explained.

It’s easy to call the ‘one food diet’ a yo-yo phenomenon.

However, even if it is a healthy food, eating only one food to lose weight can be detrimental to your health. Calorie intake is inevitably lowered, so fat is lost initially, but this ultimately leads to muscle loss and a lower basal metabolic rate.

If your basal metabolic rate decreases due to muscle loss, you may become prone to gaining weight. When you return to your original eating habits, you will gain weight more easily than before the diet due to the lowered basal metabolic rate.

Additionally, if you eat too little, your body treats it as an emergency and stores the food you eat by converting it into more fat. Aftereffects such as constipation, dehydration, fatigue, headache, and nausea may follow, and problems with blood pressure, blood sugar, and cholesterol levels may also occur.

Therefore, if your goal is to lose weight, lose weight slowly and little by little by combining diet control and exercise appropriately. If you reduce your daily calorie intake by about 500 kcal, you can lose about 0.5 kg of weight per week. The goal is to lose about 10% of your body weight over 6 months, and it is recommended to lose about 2 to 3 kg per month.
