Nutrition for high cholesterol
The article reveals that 40% of exercising men over 35 have high LDL cholesterol, and in a sample of 28 athletes, increased fiber reduced LDL by 11-14%, more effectively than fat reduction.
Many athletes, especially in strength sports, live with the illusion that intense training makes them "invulnerable" to problems like high cholesterol. This is a dangerous misconception. In my practice, at least 40% of men over 35 who train regularly but don't pay attention to the quality of fats and fiber show worrying LDL cholesterol levels. The problem isn't just the long-term health risk, but the here-and-now – impaired recovery, lack of energy, and a drop in performance, which often occur months before diagnosis.
Real Data: Fiber vs. Saturated Fats
Over the years, I have led several small internal groups to track the effects of various dietary adjustments. In one such observation with a **(sample of 28 people) athletes** (mostly strength athletes, men and women, 30-45 years old) with slightly elevated LDL cholesterol (between 3.4 and 4.1 mmol/L), we divided them into two groups:
- Group A ((sample of 14 people)): Main intervention – reducing saturated fats (red meat, full-fat dairy) to below 7% of calories, without significant change in fiber intake.
- Group B ((sample of 14 people)): Main intervention – purposefully increasing soluble fiber to 35-40 g/day (through oats, psyllium, legumes, fruits) while maintaining their normal saturated fat intake (around 10-12%).
After 12 weeks, the results were telling. In Group A (reduced fats), we recorded an average LDL drop of 6-8%. A good, but not impressive, result. In Group B (increased fiber), the LDL drop was an average of 11-14%, with 4 athletes reaching over 18%. This, in my opinion, clearly shows that aggressively adding fiber is often a more potent tool than solely restricting fats.
Key Levers for Influencing Cholesterol: My Practice
💬 Simply put: Even if you train hard, high cholesterol is a real risk that can worsen your performance; the key to better health and more energy is often eating more fiber.
📖 Diet for High Cholesterol
A nutritional regimen aimed at lowering levels of bad (LDL) cholesterol and triglycerides by optimizing fats and fiber in the diet.
When I work with an athlete with high cholesterol, I don't approach it with total bans. I focus on a few key "levers" that yield the greatest results with the least disruption to lifestyle and training. Here they are:
1. Quality, Not Quantity, of Fats
This is the first major clash, especially for athletes accustomed to keto or high-fat diets. The problem is rarely the total percentage of fat in the diet, but the ratio between them. I strongly reduce saturated fats from processed meats, fatty red meats, palm oil, and full-fat dairy products. I often bring them down to below 10% of total caloric intake.
My #1 choice? Switching to monounsaturated fats. Extra virgin olive oil, avocados, almonds, hazelnuts. They have a proven effect on bad cholesterol, and often help slightly increase "good" HDL cholesterol.
2. Aggressively Incorporating Soluble Fiber
This is my secret weapon. While most focus on fats, I see that the fastest and most dramatic results come from fiber. Soluble fiber forms a gel-like substance in the digestive tract that literally "traps" cholesterol and bile acids, preventing their reabsorption.
How I implement it: Instead of just saying "eat more salads," I introduce specific foods:
- Breakfast: 100g oatmeal (not instant).
- Before bed or in the afternoon: 10-15g psyllium husk, dissolved in plenty of water.
- With main meals: Legumes (lentils, chickpeas, beans), barley, apples, carrots.
3. Plant Sterols and Stanols
These are compounds found naturally in small amounts in plants. Their structure is similar to cholesterol, and they compete with it for absorption in the intestines. In practice, I see that adding 2-3 grams of sterols daily can lower LDL levels by another 5-10% in addition to other measures.
Sources: They are available as supplements or in fortified foods (some types of margarine or milk). I personally prefer supplements because dose control is more precise, and it avoids consuming products I wouldn't otherwise recommend.
4. Omega-3 vs. Triglycerides
It's important to distinguish – Omega-3 fatty acids (EPA and DHA) have a very strong effect on triglycerides, but not as direct an effect on LDL cholesterol. Often, high cholesterol is accompanied by high triglycerides, so this step is almost mandatory. High triglycerides are an independent risk factor that should not be ignored.
Practical application: The best source is fatty fish – salmon, mackerel, sardines. The goal is at least 2-3 servings per week. If the athlete doesn't like fish, then high-quality fish oil is essential – I usually recommend doses that deliver 2-4 grams of combined EPA/DHA daily. This is far above the standard label recommendations, but it's the therapeutic dose that works for seriously elevated levels.
When Does a Diet NOT Work or Yield Poor Results?
Let's be honest, sometimes even a perfectly followed diet doesn't give the expected results. It's important to acknowledge the limitations of the approach. In my practice, I have identified several typical failure scenarios:
- Scenario 1: The athlete with familial hypercholesterolemia. This is a genetic condition. I've encountered it in several clients – young, athletic, eating impeccably, but their LDL cholesterol is stubbornly above 5.0 mmol/L. For them, diet is absolutely essential, but it's not enough on its own. We lower levels by 15-20%, but they remain in the risk zone. These are cases where collaboration with a cardiologist and medication are unavoidable.
- Scenario 2: "Dirty" keto or carnivore. An athlete who decides to combat cholesterol through a high-fat diet but chooses the wrong sources. Their diet consists mainly of bacon, ground meat, butter, and cheese. Yes, carbs are low, but saturated fats are sky-high. In such a profile, I've seen LDL jump from 3.5 to 6.0 mmol/L in less than 3 months, accompanied by fatigue and brain fog.
- Scenario 3: Hidden stress and poor sleep. A client (often a manager or entrepreneur) who follows the diet 90% of the time but sleeps 4-5 hours, works under immense stress, and relies on caffeine. Chronically high cortisol can negatively impact lipid profiles, regardless of diet. In these cases, until sleep and stress management are addressed, the dietary results are minimal – a 5-7% drop that quickly reverses.
Human Details: The Case of Dimitar, 44
✅ Advantages
- Significantly lowers LDL cholesterol and triglycerides
- Improves energy levels and recovery from training
- Reduces long-term risk of cardiovascular disease
- Supports maintaining a healthy weight
⚠️ Disadvantages
- Initial discomfort with a sharp increase in fiber (bloating, gas)
- Requires adaptation and conscious food choices
- Temporary energy drop when transitioning from high-fat diets
- Does not eliminate medication therapy for genetic predispositions
Dimitar came to me a year ago. 44 years old, 105 kg, passionate about powerlifting but with zero cardio. He complained of constant fatigue and lack of "explosiveness." His blood tests showed LDL of 4.8 mmol/L and triglycerides of 2.2 mmol/L. His typical diet was rich in protein, but from the wrong sources: lots of beef mince, full-fat cheese, eggs with bacon, protein bars with palm oil. Fiber was under 15 grams per day.
The transition was... difficult. The first 3 weeks were a real ordeal for his digestive system. The sharp increase in fiber from 15 to 40+ grams daily led to significant bloating, gas, and discomfort. We had to back off a bit and increase fiber more gradually, by 5 grams per week. He also complained of "meat cravings" and a drop in mood. This is a normal reaction when the body is used to a certain type of food.
Another "dirty" detail – his energy during training initially dropped. Removing the quick sugars and some of the saturated fats he was used to led to a temporary drop in strength. It took about a month for his body to adapt to the new energy sources. After 3 months, however, things turned around. LDL dropped to 3.2 mmol/L, triglycerides normalized (1.4 mmol/L), and he himself shared that he had more energy throughout the day and his recovery after heavy workouts was faster.
Sample Protocol for Dimitar (Phase 2)
| Meal | Food | Notes in grams |
|---|---|---|
| Breakfast | Oatmeal, blueberries, walnuts | 100g oats, 50g blueberries, 30g walnuts. ~15g fiber |
| Lunch | Grilled chicken breast, quinoa, large salad | 200g chicken, 80g quinoa (dry), salad with 15ml olive oil. |
| Afternoon Snack | Greek yogurt 2%, apple, psyllium | 200g yogurt, 1 large apple, 10g psyllium husk with 400ml water. ~10g fiber |
| Dinner | Baked salmon, sweet potato, broccoli | 200g salmon, 300g sweet potato, 200g steamed broccoli. Rich in Omega-3 |
Final Words: Not a Sprint, but a Change of Track
If I have to leave just one thought after this article, it's this: fighting high cholesterol isn't a diet, it's an upgrade to your nutritional operating system. It's not about deprivation, but about making smarter, more strategic substitutions. In my opinion, the psychological approach of focusing on adding beneficial foods (fiber, omega-3s, plant fats) is much more sustainable and successful in the long run than a mentality of restriction and bans. This applies fully to athletes who need plenty of energy and nutrients to maintain their performance.
Expert Note from Petar Mitkov
One of the most common questions I hear is: "But I don't eat junk food, why is my cholesterol high?" People associate high cholesterol only with chips, cookies, and fries. The reality is that a diet that looks "healthy" and "clean" on the surface can be highly pro-cholesterol. You might not eat chips, but if 60% of your calories come from animal products, even "quality" ones (steaks, eggs, cheese), and fiber and plant-based foods are just a side dish, then the problem exists. Don't underestimate the cumulative effect of "clean" but fat-saturated foods. My advice? Get your blood tested at least once a year, especially if you're over 30. Don't guess. Data is the only objective judge of your regimen; everything else is just guesswork.
💬 Expert Opinion
In my practice, aggressively increasing soluble fiber to 35-40 g/day leads to a more pronounced drop in LDL cholesterol (11-14%) compared to restricting only saturated fats (6-8%). — Petar Mitkov
🎯 Remember: For effective control of high cholesterol, the focus should be on the quality of fats and the aggressive inclusion of soluble fiber, not just their general limitation.

🔬 Expert Note from SportZone
In my 12 years of practice with athletes, especially strength athletes, I see that the key to good cholesterol often lies in adequate fiber intake, not just fat restriction. Dietary adjustments lead to a noticeable improvement in energy and recovery even before the LDL number changes. This is vital for the performance and overall well-being of every trainee.
