The impact of lifestyle changes on LDL cholesterol in three months
LDL cholesterol, commonly referred to as "bad cholesterol," is a key risk factor for cardiovascular diseases. Its management can be significantly influenced by lifestyle changes. However, many underestimate how effective small and targeted changes can be – and how quickly results can begin to show.
The table below summarizes various measurable health variables, the changes in which over a three-month period can lead to a significant decrease in LDL cholesterol levels. It includes both physical metrics such as weight, waist circumference, and muscle mass, as well as so-called quieter health variables like sleep, recovery, stress, and gut microbiome diversity.The combined effect of all these can, at best, reduce the need for medication, prevent diseases, and improve overall well-being.
Note: Percentage changes are estimates and are based on averages from several studies. Individual responses may vary depending on life circumstances, genetics, and baseline levels.

Effect is often stable and reproducible, approved at EU and FDA levels |
Reduction of saturated fat |
-10 g/day |
5–10 % | Best effect when replaced with soft fats |
Reducing alcohol consumption |
From moderate levels to zero |
2–5 % |
The effect is amplified if the baseline level is high |
Quitting smoking |

Indirect effect + increase in HDL |
Increasing physical activity |
+150 min/week of aerobic exercise |

2–5 % |
Sleep regulates metabolism and hormonal function |
Decrease in stress levels (PSS) |
25 → 15 points |
3–10 % |
The effect is greater if stress has been chronic |
Increase in HRV (recovery) |
RMSSD +20 % |
2–5 % |
Good HRV reflects autonomic balance |
Diversity of the gut microbiome |
Shannon index +20 % |
3–7 % |
Conveys effects related to cholesterol metabolism |
Decrease in CRP (inflammation) |

2–6 % |
Low-grade inflammation disrupts LDL receptor function |
Example customer: Timo made a lifestyle change
Timo is a 60-year-old man approaching retirement age who has recently become aware of his health condition.He weighs 100 kg and is 182 cm tall, which means a body mass index of 30.2 – mild obesity. The waist circumference is 105 cm, and the body fat percentage is about 25 %, which particularly indicates visceral or intra-abdominal fat.
Health background
Exercise is occasional: one walk per week, nothing more.
Diet focuses on high meat consumption, especially sausages, cold cuts, and high-fat dairy products. Vegetables have been minimal.
Timo quit smoking 3 years ago, but alcohol consumption is still 6–8 servings per week, especially on weekends.
There are heart and vascular diseases in the family, which increases his hereditary risk.

Timo also snorts heavily, and he is diagnosed with sleep apnea, which explains his fatigue and fluctuations in alertness. He receives a CPAP device, which he starts using immediately.
Lifestyle change begins: January 1st
Timo makes the decision to change his lifestyle and starts a structured program based on researched methods:
🥗 Nutrition:
Red meat is completely eliminated – replaced with fish and plant-based protein sources.
Saturated fats are eliminated: dairy products are limited to low-fat options.
Vegetables are added to every meal – a total of over 500 g per day.
Beta-glucan is added at 3 g/day, e.g., from Glucaven.
-
Alcohol is limited to weekends, and half of the servings are non-alcoholic.
🏃♂️ Exercise:
Daily 45-minute walk in hilly terrain (aerobic basic endurance).
Gym 2 times a week, a program to develop strength and flexibility.
Weight drops 0.5 kg per week → over three months -6 kg .
😴 Recovery and stress:
CPAP treatment for sleep apnea improves sleep quality and alertness.
Experienced stress decreases: no more morning fogginess and irritability.
Gut health improves: a high intake of vegetables and fibers supports the microbiome.
Inflammation markers (CRP, IL-6) decrease.

✅ Timo's new situation – towards heart health
Timo's lifestyle change has produced significant health effects in just 3 months :
Cholesterol levels are almost at target levels without medication
Triglycerides and CRP have clearly decreased – metabolic inflammation has calmed down
Waist and body fat percentage have decreased, visceral fat has reduced
Sleep, recovery, and stress management have improved – quality of life is better
Timo is now continuing the program, and the next goal is to get the LDL level below 2.5 mmol/l, which could be realistic in the next 3–6 months.
