What we truly need might not be more health knowledge, but rather knowing which knowledge is relevant to your own body.
Over the years, we have been exposed to an increasing amount of health information.
Today someone tells you that oats can prevent aging, tomorrow someone tells you that blueberries are good for your body;
someone recommends a certain exercise, someone empha0.875rems the importance of sleep, and someone summarizes "a few things you must do after the age of 50".
All of these sound reasonable.
But recently, I suddenly realized a problem:
"Being beneficial to the body" does not equal "this is what I need right now".
There is actually a very important step missing between these two concepts - understanding your own body.
From "What's good" to "What do I need"
In the past, when we saw a "anti-aging food ranking list", our first reaction was usually:
This is good, I should eat it.That one is also good, I can add it in.
When seeing a certain exercise method, we would think:
This is good for the heart and lungs, I should also do it.
When hearing that sleep is very important, we would start to research:
How to have high-quality sleep?
So, we kept learning and constantly added things to our lives.
But very rarely did we stop to ask:
What is the current state of my body?
If we don't know our own body condition, then "what to eat", "what to exercise", "how to sleep" can easily become a blind following.

The health check-up report introduced me to a concept—lipid levels.
Around the time of this physical examination, I started paying attention to my lipid profile.
Coincidentally, I came across a video about lipids that mainly discussed low-density lipoprotein cholesterol (LDL-C).
One question in particular caught my attention immediately:
Why do some people, who aren't overweight, eat relatively light diets, and rarely consume rich or fatty foods, still have elevated LDL-C levels?
This was exactly my own confusion.
I'm naturally slim, don't eat large portions, and have always been mindful of eating light meals with plenty of vegetables. I've even tried incorporating dietary principles such as the Mediterranean diet, Japanese diet, and the "211 plate" method into my daily routine.
Yet, despite all this, my LDL-C level on this test was still above the reference range indicated in the report.
My LDL-C reading was 3.7 mmol/L, while the upper limit of the reference range was 3.36 mmol/L.
As a result, the report flagged abnormal lipid levels and advised me to adopt a balanced, low-fat diet with more vegetables, recommended retesting after two months, and follow-up with an endocrinologist.
I began asking myself:
"Why has my lipid profile changed like this?"
Originally, blood lipid levels are not as simple as just "eating too much meat".
Through this video and subsequent understanding, I realized that there are actually many factors influencing blood lipid levels.
Diet is certainly one of them, but it is not simply equivalent to "eating meat".
The saturated fat and trans fat in the diet can affect LDL-C; on the other hand, excessive intake of refined carbohydrates and added sugars is more often associated with metabolic problems such as elevated triglycerides.
So, even if a person doesn't eat much fatty meat, if the overall dietary structure is not ideal, blood lipid levels may still be problematic.
This made me realize for the first time:
"Having a light diet" does not mean that all lipid risk factors have been eliminated.
Age and physical changes may also be involved.
As one ages, lipid levels may change. After women enter the perimenopausal and menopausal periods, the level of estrogen changes, and lipid levels may also change accordingly.
In addition, genetic factors are also worthy of attention.
Some people, even with a normal weight and a relatively healthy lifestyle, may have higher LDL-C due to genetic factors.
Some diseases and medications may also affect lipid levels, such as hypothyroidism, chronic kidney disease, diabetes, and certain medications.
Also, people with long-term high stress, frequent late nights, or smoking, as well as the effects of some medications, can all cause abnormal lipid levels.
Therefore, when a person's LDL-C is abnormal, it is not just:
"Did I eat too much meat?" but rather:
"Among my diet, exercise, sleep, age changes, family history, and other health factors, which ones might be related to this indicator?"
Blood lipid levels are not an isolated number.
Starting from "what to eat", we can further understand diet.
The video also mentioned many foods that we are very familiar with:
oats, legumes and bean products, vegetables, fruits, fish, nuts, olive oil, etc.
Among them, the soluble dietary fiber β-glucan in oats does indeed help improve LDL-C;
in general, a healthy diet for cardiovascular health usually empha0.875rems vegetables, fruits, whole grains, legumes, nuts, seeds, and unsaturated fats, while reducing saturated fats, trans fats, added sugars, and highly processed foods.
But this time, my understanding of these foods is different from before.
Previously, when I saw "oats are beneficial" "nuts are beneficial" "deep-sea fish are beneficial", my first reaction might have been:
Then I'll just eat more of it.
Now, I would first ask:
Why is it meaningful for me?
For example, if my goal is to improve LDL-C, then what might be truly important is not simply increasing a certain "superfood" alone, but rather re-examining the entire dietary structure, including fat sources, dietary fiber, refined carbohydrates, added sugars, and overall energy intake.
This makes me realize again:
Healthy foods are not an endless list that can be added to.
What truly matters is the overall dietary pattern and whether it aligns with one's health goals.
Exercise should not merely be "for anti-aging".
In the past, when I persisted in exercising, I mainly thought of:
Maintaining a good figure, enhancing physical fitness, and delaying aging.
But now, after linking exercise with my own health check-up indicators, it has acquired another meaning.
Regular physical activity helps improve overall cardiovascular metabolic health and can also have a positive impact on blood lipids.
For average adults, the current physical activity guidelines in the United States recommend 150–300 minutes of moderate-intensity aerobic exercise per week, and at least 2 days of muscle-strengthening activities per week.
My own exercise habit has actually persisted for a long time:
Running every day, doing yoga, and later adding planks, push-ups, squats, and weight training with dumbbells.
Although it is not as systematic as professional training in the gym, it has formed a relatively stable lifestyle for me.
However, after this abnormality in blood lipids occurred, I began to have a new question:
If I have been exercising, why is this indicator still problematic?
This has instead made me more aware that:
A healthy behavior being effective does not mean it can explain all the changes in the body.
Exercise is just one factor influencing the body.
It needs to be considered together with diet, sleep, age, genetics, and other health factors.
Sleep has transformed from a "health tip" to a part of body management.
Sleep used to be a very familiar health topic for me.
Everyone knows:
Don't stay up late and maintain a regular schedule.
But previously, these words felt more like a general health recommendation to me.
Now, I start to try to connect it with body indicators.
Insufficient sleep or poor sleep quality is associated with cardiovascular health risks, so sleep is not an independent issue completely unrelated to blood lipids, blood sugar, weight, etc.
So I began to re-understand:
Diet, exercise and sleep are not three mutually independent "anti-aging techniques".
In fact, they are all lifestyle factors that affect the long-term state of the body.
The annual physical examination in 2026 enabled me to start building my own health record.
Yesterday , I just completed the annual physical examination for 2026.
This physical examination had an experience that left a very deep impression on me, which was having a professional medical guide accompanying me.
You don't have to think about:
What to do first?
Where is the next step?
When to queue up?
She will arrange the process in advance, and before you finish one item, the next one is already connected.
You just need to follow her instructions step by step.
This made me suddenly think:
Health management should also have its own process.
The physical examination doesn't end after it's done.
The report doesn't end after you glance at it and see if there are any abnormalities.
What's truly meaningful is:
This year's data → Last year's data → Long-term changes → Find the indicators that need attention → Understand the possible influencing factors → Adjust lifestyle → Re-examine.
So after this report comes out, I will pay special attention to the lipid indicators, especially the change in LDL-C.
At the same time, I will carefully pay attention to the suggestions given in the report and carry them out seriously.
Starting from one indicator, medical knowledge is not as distant as it seems.
Medical knowledge is indeed profound.
Ordinary people cannot understand all medical knowledge at once.
But now I suddenly feel that perhaps we don't need to understand everything at the very beginning.
We can start with a problem that we are truly concerned about.
For example, this time, I started with LDL-C.
First, figure out:
What is it?
Why does it change?
What factors might affect my situation?
How can diet, exercise and sleep help me?
Why did the doctor recommend a re-examination?
What happened after the re-examination?
By doing this step by step, the originally very complex medical report suddenly becomes understandable.
The key is not that I suddenly became a medical expert.
Rather, it is:
I began to truly value my own body.
Just like studying how to make money, one should also study how to manage one's own body.
I suddenly realized that there is a very interesting similarity between health and wealth.
When studying how to make money, we don't simply copy the methods of others just because we see them earning money.
We will study:
• How much resources we have
• What our goals are
• Where the risks lie
• How the data is
• Which factors truly affect the outcome
• What strategies should be adopted
• Whether the final result verifies our judgment
Then why can't the body be treated in the same way?
Wealth needs to be managed, and so does the body.
Making money requires learning about finance, investment and business knowledge.
Managing the body also requires learning about physical examination indicators, nutrition, exercise, sleep and disease risks, etc.
But there is a common point between the two:
Knowledge is not to help us remember more answers, but to enable us to have better judgment abilities.
