title: "Diet Foods — Looking at Protein and Dietary Fiber, Even from a Traditional Korean Medicine Perspective"
The question I hear most often in the clinic is "Doctor, what on earth should I eat to lose weight?" I've struggled with the same issue myself, so I really understand that feeling. Today, I'll organize some foods that come in handy during dieting, along with insights from a traditional Korean medicine perspective.

Why do some people gain weight and others lose it eating the same amount
The common trait of foods that help with dieting is surprisingly simple. Foods that are low or moderate in calories but high in protein and dietary fiber, providing long-lasting satiety. If even one meal consists mainly of white bread, snacks, and fried foods, blood sugar spikes quickly and hunger returns fast. Conversely, when rich in protein and dietary fiber, food stays in the stomach longer, delaying hunger until the next meal.
There's one crucial point to address here. You can't lose weight with just a single "diet food." Total calorie intake, a balanced diet, and exercise must all work together for greater effectiveness. No food functions like a "pill that melts away fat."

Protein Foods That Are Great for Daily Rotation
These are the foods I frequently suggest when I tell patients in the clinic, "For the next 1 week, please focus on getting enough protein first."
- Eggs — Approximately 6.24g of protein per 1 large egg. There are quite a few studies showing that eating eggs in the morning reduces hunger before lunch, which helps in reducing total calorie intake. Any form is fine: boiled eggs, steamed eggs, or scrambled eggs.
- Greek Yogurt (Plain, Unsweetened) — A high-protein food with approximately 14.9g of protein per 1 serving (170g). Instead of pouring syrup, pairing it with berries or a slice of apple adds dietary fiber to the protein, making the feeling of fullness last longer.
- Cottage Cheese — About 12.8g of protein per 1 serving (110g). Low-fat cottage cheese has a lower energy density than regular cheese, at approximately 163kcal per 1 cup.
- Lean Meat and Fish — Lean cuts such as tenderloin or top round are excellent protein sources. I recommend grilling, steaming, or using an air fryer instead of frying or using butter. Salmon provides approximately 17.3g of protein per 85g, along with Omega-3.
A general guideline for recommended protein intake during weight loss is approximately 1.2~1.6g per 1kg of body weight. For someone weighing 60kg, this means aiming for about 70~100g per day.

If you only focus on protein, you may end up with constipation. That's why vegetables can't be skipped.
- Non-starchy vegetables — Leafy and stem vegetables like lettuce, cabbage, cucumber, and broccoli typically provide 20~30kcal per 100g, making them very low in calories while being rich in dietary fiber. About 90g of cabbage is sufficient as a side dish for one meal.
- Cucumber — Contains roughly 9~13kcal per 100g, packed with water and dietary fiber. Keeping sliced cucumber on hand makes a great snack alternative when hunger strikes instead of chips.
- Berries and apples — Pairing these with Greek yogurt lets you combine protein and dietary fiber in a single bowl.
The recommended dietary fiber intake is at least 20~25g per day, but the Korean average falls short of this. Making it a habit to add a handful of vegetables to every meal creates a surprisingly big difference.
The Perspective at Baekrokdam Korean Medicine Clinic on Diet Foods
In Korean traditional medicine, the same food can produce different effects depending on a person's constitution and digestive health. Some people experience bloating and cold extremities after consuming substantial amounts of cold-natured vegetables and fruits. Others struggle with poor sleep due to heavy digestion after increasing their protein intake.
During consultations, food selection begins with assessing digestive capacity, body temperature, and edema tendencies. For those with cold stomachs and frequent swelling, lightly blanched vegetables are preferable to raw ones. Individuals with weak digestion start with gentler protein sources like eggs and yogurt. When herbal medicine is incorporated, diet supports the treatment's effectiveness, making the approach to eating as crucial as what foods to avoid.
## Practical Points You Can Start Changing Today
Rather than an elaborate meal plan, one or two small habits can change your 1 weeks.
- Always include one protein source in the morning — choose one: boiled eggs 1–2 pieces, or one cup of Greek yogurt 170g
- A handful of vegetables with every meal — focus on non-starchy vegetables, light varieties around 20kcal per 100g
- Pre-cut cucumber and carrot sticks and keep them within reach for when you feel hungry
- Just change the cooking method — switch from frying and butter to grilling, steaming, or air frying
- Do not keep white bread, snacks, or sugary drinks at home
Instead of memorizing numbers, try asking yourself once each time: "Is the food in my hand right now protein, dietary fiber, or refined carbohydrates?" That simple classification alone can change your choices at each meal.
No single food will dramatically reduce your weight all at once, but a table centered on protein and dietary fiber is what patients seen in our clinic have been most consistently able to change. If you would like to adjust your meal plan according to your body constitution and digestive condition and receive herbal management together, please consult with us through the Baekrook-Gambi-jeong program at Baekrookdam Korean Medicine Hospital. We will look into your everyday eating habits and body constitution together, and find a diet food composition that you can follow without strain.
