Kim Nayoung Reveals Her Successful Diet Tips

Recently, she uploaded a video titled "Kim Na-young's Weight, Diet Rules, Abs Workout, etc. Q&A!" on her YouTube channel 'Kim Na-young's nofilterTV'. In the video, she said she is 170cm tall and weighs 50.3kg, and added, “I went on a diet when I once weighed up to 60kg."

Kim Na-young said, "I tried mono diet, but It was too difficult. So, the basic idea I have is 'You can eat anything, but reduce the portion by half." She also mentioned, "I don't eat anything after 7 PM, and I find light walking on an empty stomach in the morning helps."

Mono Diets Can Cause Nutritional Deficiency and Muscle Loss

Many people attempt mono diets like Kim Na-young did in the past to lose weight. While these diets can be harmful, they do not provide a balanced intake of nutrients, leading to nutritional deficiencies and muscle loss, which lowers your basal metabolic rate. This can result in weakened immunity and decreased overall physical fitness.

In contrast, the diet tips Kim Na-young revealed can be followed healthily over the long term. By eating a little of what you want, you can reduces stress and get enough of necessary nutrients. The Korean Society for the Study of Obesity advises that reducing daily caloric intake by about 500 Kcal to lose weight without health risks. They also recommend a balanced diet of carbohydrates, proteins, fats, vitamins, and minerals.

Controlling Meal Portions and Exercising Are Essential

Controlling portions and exercising are essential. While there are many ways to exercise, brisk walking, as Kim Na-young mentioned, is known to be effective for weight loss. A 12-week walking program by the Korea National Park Service showed that walking 12km at least 2-3 times per week reduced the body mass index by an average of 0.23kg/㎡. Walking on an empty stomach in the morning can be more effective as the body uses stored fat for energy after fasting during sleep.

Avoiding late-night snacks is also important. Eating late at night increases the risk of obesity and can cause diabetes and hypertension. Late-night snacks are often high in sugar, sodium, and calories.

A study by Johns Hopkins University found that eating late at night increases the likelihood of obesity because less fat is burned. People who ate at 10 PM had higher blood sugar levels the next morning compared to those who ate regularly at 6 PM. They also had higher cortisol levels, a stress hormone.
