Diet Meal Reviews — Examining Intermittent Fasting, Protein, and Calories

The phrase I hear most often in the consultation room is, "I followed a diet I saw on YouTube, and while I lost weight at first, it came back quickly." There are truly many people who start based only on reviews and then become exhausted.

Why numbers drop quickly in reviews

Looking at blog reviews, posts often appear stating that they lost 1.7kg in 4 days through 16:8 intermittent fasting and a high-protein diet. This is a method of finishing meals within 8 hours after a 16-hour fast. The menu consists of things like 1/2 an apple, 2 eggs, 15 almonds, Greek yogurt, and konjac rice for breakfast, and 150g of chicken breast and 1/2 a sweet potato for lunch.

The problem is that the total calories are estimated to be around 900~1,100kcal per day. One nutritional resource recommends a minimum of 1,0001,200kcal for adult women and 1,2001,500kcal for men; if it is lower than this, water and glycogen are lost first in the beginning, causing weight to drop sharply. The review author also wrote that "the speed decreased after 4 days." You can read this as a signal that the numbers from the first few days are not necessarily body fat loss.

Landscapes seen in Shin Bong-sun 2-week diet reviews

These days, the reviews being posted most frequently are about the Shin Bong-sun 2-week diet. It involves a Foodology set (Toxology + Burningology) for 14 days. The flow is: cleanse with purple ampoules from day 1 to 3, recovery food on day 4, and taking 1 packet of Burningology per day from day 5 to 14. The price is approximately 5.9 million won per 1 set.

Gathering the reviews, those who chose the hard course (consuming only ampoules without eating anything for 3 days) frequently write that "the dizziness and hunger were too severe." There were many evaluations that the normal course was more bearable because it included a protein-based diet, such as chicken breast. While short-term numbers look good, a common pattern is that weight rises again when returning to a general diet during the recovery food stage. Advertising numbers such as "5kg, 10kg in 2 weeks" are far from the recommended weight loss speed.

How Baekrokdam Korean Medicine Clinic views these reviews

In our consultation room, we look at the weight loss speed before the numbers in reviews. Even in domestic medical information, a healthy weight loss speed is summarized as 0.51kg per week, or 12kg in 2 weeks. To lose 1kg of body fat, a cumulative deficit of approximately 7700kcal is required. Converted to a daily basis, it is realistic to reduce intake by 500~800kcal or increase activity.

In Korean medicine, even for the same obesity, dietary responses vary significantly depending on the constitution, such as Yin deficiency, Qi deficiency, or Phlegm-Dampness. Even with the same chicken breast diet, those with a Phlegm-Dampness constitution may see good numbers as edema is removed first, whereas those with a Qi deficiency constitution may quickly experience dizziness and lethargy on a low-calorie diet. This is why, if you follow reviews exactly, some people lose weight well while others only experience a breakdown in their physical condition.

I also tell my patients, "Do not follow review diets exactly; instead, try recording for just one week what signals appear first in your own constitution." Depending on whether it is dizziness, constipation, or edema, the way the diet is adjusted differs completely.

Practical Tips You Can Start Applying Today

When referring to testimonials, just keeping the following in mind is enough.

  • Start by reducing your total daily intake by 500~800kcal compared to usual. Suddenly dropping below 900kcal leads to muscle loss and the yo-yo effect.
  • Make sure to include protein at every meal. There's a reason chicken breast 150g, 2 eggs, and Greek yogurt never fail to appear in testimonial meal plans.
  • 16:8 intermittent fasting is about narrowing your eating window, not about starving yourself. You need to get enough protein and vegetables within 8 hours to maintain your condition.
  • Don't be swayed by short-term testimonial numbers. Whether it's been 2 weeks or a month, whether the pace is 0.5~1kg per week, what's more important is whether it stays consistent.
  • If you experience signals like dizziness, menstrual irregularity, or insomnia, immediately loosen your diet plan. Your body's signals take priority over testimonials.

While testimonials are good for setting a baseline, in the end, if the process of tailoring it to fit your own body is missing, even following the same meal plan will yield different results. At Baekrokdam Korean Medicine Hospital, we handle body constitution diagnosis, Baekrok Gambi-jeong (Gambi-jung tablets) prescription, and diet/lifestyle habit coaching as one package. If you've tried the testimonial meal plan two or three times and find yourself back at square one, the fastest way forward is to come in for a consultation where we can identify your personal patterns together.

I have met many patients who came after visiting multiple medical institutions and departments for persistent or recurrent conditions. Symptoms normally handled by different specialties—such as abdominal pain, headaches, palpitations, dizziness, and insomnia—may overlap in one person. Sometimes there is no clear improvement despite taking medication for each symptom, and being unwell gradually becomes part of daily life. In these cases, I look beyond individual diagnoses and examine how the symptoms connect and change together. Asking only about the most uncomfortable symptom today does not reveal the full course. I look at when the body first began to change and what happened after illness, surgery, childbirth, or starting and stopping medication. I also review changes in weight, diet, and sleep, then trace which symptoms improved with previous treatment and which remained. Test results, diagnoses, and the course of previous treatment are important for understanding the current condition. Clinical research in modern Korean medicine, physiological and pathological research in modern medicine, and observations recorded in classical Korean medicine texts offer different perspectives on the same body. Rather than fitting a patient into one perspective, I consider what each can and cannot explain and look for clues that connect symptoms and treatment histories that were previously considered separately.
