The key to dieting: Reducing carbohydrates! A detailed guide on how to do it right.

One of the first methods that comes to mind for dieting is reducing carbohydrates. Many people know that cutting carbs leads to weight loss, but simply starving yourself or drastically reducing them without a plan can harm your health. Here’s a detailed guide on how to smartly manage carbohydrate intake to successfully lose weight and stay healthy.

​Why does cutting carbs lead to weight loss?

Reducing carbohydrates is effective for weight loss because of the principle of energy metabolism in our bodies. Our bodies use carbohydrates first to get the energy needed for daily activities. If the ingested carbohydrates are not all used up, they are stored as glycogen in the liver and muscles. Once this storage is full, the remaining carbohydrates are converted into fat and stored throughout the body.

​However, when you reduce your carbohydrate intake, your body starts looking for other energy sources to make up for the deficit. At this point, it begins to break down the fat already stored in your body for energy. This process leads to a reduction in body fat, which naturally results in weight loss. Additionally, carbohydrates have a property of attracting water, so reducing their intake can cause a temporary drop in body water, making it seem like you're losing more weight.

​The difference between 'bad' carbohydrates and 'good' carbohydrates

Knowing that not all carbs are the same is the first step to smart carbohydrate management. Carbohydrates can be broadly divided into 'bad' and 'good' types.

​'Bad' carbohydrates are refined carbohydrates that cause a rapid spike in blood sugar. This includes white rice, bread and noodles made from white flour, and sugary snacks, cakes, and drinks. These foods are quickly digested and absorbed, leading to a sharp rise in blood sugar, which promotes insulin secretion and rapid conversion of excess sugar into fat. The rapid rise and fall of blood sugar can also make you feel hungry sooner, leading to overeating.

​On the other hand, 'good' carbohydrates are also known as complex carbohydrates and are foods that raise blood sugar slowly. Examples include brown rice, whole grains, oats, beans, vegetables, and fruits. They are rich in dietary fiber, which slows down digestion, keeps blood sugar stable, and helps you feel full for longer. They are also packed with essential nutrients like vitamins and minerals, which can be beneficial for supplementing a diet. For weight loss, it's crucial to minimize the intake of 'bad' carbs and replace them with 'good' ones.

​Practical tips for successful carbohydrate management

Here are some specific ways to practice reducing carbohydrates. By learning how to eat smartly instead of just starving yourself, you can lose weight healthily without the yo-yo effect.

  1. ​Switch from white rice to mixed-grain rice Changing your daily staple, rice, is the most effective step. While white rice is a typical 'bad' carbohydrate that raises blood sugar quickly, mixed-grain rice with brown rice, barley, beans, millet, and sorghum is rich in fiber, digests slowly, and provides a lasting feeling of fullness. If it's hard to adjust initially, you can gradually increase the ratio of mixed grains, starting with 7:3 or 5:5 with white rice.
  2. ​Reduce consumption of flour-based foods Many of the breads, noodles, and snacks we eat daily are made from flour. While they taste good, they are the enemy of dieting. It's especially common to eat bread or noodles as a meal substitute, so you need to make a conscious effort to reduce them and replace them with healthier options. Choosing whole-grain bread or whole-wheat pasta can be a good alternative if you're hungry.
  3. ​Increase protein and vegetable intake When you reduce your carbohydrate intake, your body can feel hungry more easily. At this point, you should increase your protein and vegetable intake to feel full. Protein-rich foods like chicken breast, fish, tofu, and legumes help maintain muscle mass, while salads and various vegetables provide fiber, vitamins, and minerals that aid in metabolism.
  4. ​Switch to healthier snacks Snacks like cookies, chocolate, and sugary drinks, which you might eat without thinking, are the main culprits sabotaging your diet. Instead, switch to healthier snacks like nuts, cherry tomatoes, plain yogurt, or eggs. This will prevent unnecessary calorie intake and ensure you're getting nutrients.

​Important considerations for a carbohydrate-reducing diet

While reducing carbohydrates is an effective dieting method, overdoing it can harm your health. Here are some important precautions to keep in mind for a healthy diet.

  1. ​Avoid extreme carbohydrate restriction Extremely low-carb, high-fat diets have gained popularity, but they can be harmful in the long run. If your body lacks carbohydrates, its primary energy source, you may experience side effects like poor concentration, lethargy, and headaches due to a lack of glucose for brain function. Extreme diets also have a high probability of leading to the yo-yo effect. It's best to maintain a moderate amount and focus on 'good' carbohydrates.
  2. ​Always combine with exercise While you can lose weight through diet alone, the effects are much greater when combined with exercise. Aerobic exercise is effective at burning body fat, and strength training boosts your basal metabolism, making it harder to gain weight. By managing your carb intake and exercising consistently, you can build a healthy body with less body fat and more muscle mass.
  3. ​Sufficient hydration is essential Since reducing carbohydrate intake can also decrease your body's water content, you should drink more water than usual. Sufficient hydration helps smooth metabolism and flush out waste, enhancing the effect of your diet. It's good to get into the habit of drinking about 1.5 to 2 liters of water a day.
  4. ​Adjust based on your activity level and health condition Generally, it's recommended that carbohydrates make up 45-65% of your total daily calorie intake, but this is just a general guideline. It should be adjusted based on your personal activity level and health condition. For example, people with high activity levels like athletes may need more carbohydrates. It's a good idea to plan a diet that suits you and, if necessary, consult with a professional for guidance.

​Additional explanations related to carbohydrates

Glycemic Index (GI)

This index indicates how quickly the carbohydrates in a food raise blood sugar. The higher the GI, the faster the blood sugar rises. White rice, white bread, and sugar are typical high-GI foods. In contrast, brown rice, whole grains, and vegetables have a low GI, making them more suitable for dieting.

​The importance of protein

When you reduce your carbohydrate intake, your body might start using protein stored in your muscles for energy. This can lead to a loss of muscle mass and a lower basal metabolic rate. To prevent this, it's crucial to increase your protein intake as you decrease your carbs. Protein also helps you feel full for longer, which can suppress your appetite.

​Dietary fiber

Dietary fiber is a type of carbohydrate that is not digested and passes through to the gut. It increases the feeling of fullness and prevents a rapid rise in blood sugar. It also promotes regular bowel movements and helps prevent constipation, making it an essential nutrient to include in your diet. It is abundant in fruits, vegetables, seaweed, and whole grains.

On your way to work during the rainy season, are you done worrying about wet shoes? Everything on the shoe cover you don't know.



During the rainy season, many office workers suffer from rain-soaked shoes and socks. Especially for men who need to wear suits, the options are even narrower. You can be wary of wearing sandals or boots, and you are worried that your precious shoes will be damaged by rainwater. As an item to solve these problems, sneaker silicone covers are attracting attention recently. Could this shoe cover be a really practical solution?
The reason why I'm no longer afraid of going to work in the rain.
Many office workers envy young women wearing pretty boots or sandals on rainy days. Especially for men who need to dress up in suits, choosing shoes on rainy days is not difficult. Shoes are likely to get wet with rainwater and dampen socks, and it is also cumbersome to carry shoes separately.

But now there are items that can relieve these concerns. It's the shoe cover. The shoe cover is a form of overlaying over the shoes that were previously worn, effectively preventing the shoes from getting wet. In particular, sneaker silicone covers are popular with many people because they are light and easy to carry.

Silicone shoe cover, when I used it myself
Silicone shoe covers are easily available at Internet shopping malls. The advantage is that the price is low, so you can purchase it without much burden. Most of the covers are in the shape of sneakers, but they are not very awkward even if they are put on the shoes. Rather, it goes well with formal attire and becomes an unexpected fashion item.

This cover covers the entire shoe without any room for rainwater to seep in, so you don't have to worry about getting your shoes and socks wet even on rainy days. In particular, even old shoes with cracked soles and watering in can be worn like new shoes with just a cover, which is economical. However, there are a few points to note.

First, be careful not to slip. Due to the nature of the silicone material, it can be slippery on wet marble floors or subway station floors. Therefore, you should be especially careful when walking up and down stairs or on wet floors.

Second, it is poorly ventilated. Because silicone seals the entire shoe, it can feel a bit stuffy in the summer months when you sweat a lot. It is good to use it with this in mind.

Silicone shoe cover, what size is suitable for me?
When purchasing silicone shoe covers, choosing a size is very important. In general, the L (large) size is suitable for shoes of 255 mm or more, and the XL (X-large) size is suitable for shoes of 275 mm or more. If you choose a size that is too small, it will not be easily covered on your shoes and will be torn, and if you choose a size that is too large, it may come off while walking. Therefore, you should choose the correct size for the shoe size you wear.

Shoes are worried during the rainy season, and now silicone covers are used to solve them.
You can stop worrying about wet shoes on your way to work during the rainy season. Silicone shoe covers can be a great alternative to protecting shoes at low prices and creating a pleasant way to work. Although there are disadvantages such as slipperiness and ventilation problems, it is enough to bear compared to the unpleasantness of rain-soaked shoes and socks.

If you purchase sneaker silicone covers, especially large sizes, you can use them without any problems with most men's shoes. Now, even on rainy days, you can go to work confidently.
