lipid.siteLow saturated fat (TLC-style)
Swaps foods rich in saturated fat (butter, fatty meat, full-fat dairy, coconut and palm oil) for unsaturated fats, the single change with the most consistent LDL-C evidence.
LDL-C effect in studiesAbout 10 to 16% lower LDL-C in trials, more for people who started high in saturated fat
This section shares information about dietary patterns and the research on them. lipid.site doesn't recommend any particular diet, and nothing here is medical or nutrition advice for you. Talk with your clinician or a registered dietitian before making big changes, especially if you have diabetes, kidney disease, an eating-disorder history, are pregnant or breastfeeding, or take blood thinners or other daily medicines. Food changes can work alongside cholesterol medicines; they usually don't replace a medicine your clinician prescribed.
Eat more
- Olive, canola, peanut, sunflower or soybean oil
- Fish, poultry without skin, beans and lentils
- Low-fat or fat-free dairy
- Vegetables, fruit and whole grains
Eat less
- Butter, ghee, lard and cream
- Fatty and processed meats (sausage, bacon, ribs, salami)
- Full-fat cheese and ice cream
- Coconut oil and palm oil
- Pastries, fried fast food and anything with partially hydrogenated oil (trans fat)
A typical day
- Breakfast: whole-grain toast with peanut butter, a banana, and low-fat yogurt
- Lunch: turkey or chickpea wrap with lots of vegetables and hummus
- Dinner: salmon or tofu roasted with vegetables in olive oil, with brown rice
Who it may suit
Anyone whose current diet includes lots of butter, cheese, red or processed meat, or coconut oil. Works with any cuisine.
Things to watch
- Replacing saturated fat with refined carbs (white bread, sweets) gives less benefit; swap toward unsaturated fats and whole foods.
- Low-fat processed foods can be high in sugar and sodium.
- Response varies: people who started with very high saturated fat intake tend to see the biggest change.
Tell me more
Decades of feeding trials show that replacing saturated fat with unsaturated fat lowers LDL-C. A pooled analysis of free-living trials found the older Step I and Step II low-saturated-fat diets lowered LDL-C by about 12% and 16%. A Cochrane review found that cutting saturated fat for at least 2 years reduced combined cardiovascular events by about 21% (moderate-quality evidence). The 2026 ACC/AHA dyslipidemia guideline recommends replacing saturated and trans fat with mono- and polyunsaturated fat (Class 1).
Evidence strength: strong means several good trials agree; moderate means trials agree but are small, short or varied; limited means a few small trials or mostly indirect evidence. LDL-C numbers are averages from studies. Your own result can be larger, smaller or zero.
- Cost: neutral to cheaper if you swap red meat for beans and poultry.
- Effort: low. You keep familiar meals and change the fat and the protein.
- Eating out: ask for grilled over fried, oil instead of butter, and sauces on the side.
- Nutrition labels help: saturated fat is listed in grams. The usual target is under 10% of calories (about 22 g on a 2,000-calorie day); older TLC advice used under 7%.
Many posters who report large drops tracked saturated fat grams daily, often after cutting red meat, butter and cheese.

Your results will vary
Diet affects LDL-C differently from person to person. Two people on the same plan can see very different results, and genetics (including familial hypercholesterolemia and Lp(a)) set a floor that food alone may not move. The only way to know what a change does for you is to recheck your labs, usually after 6 to 12 weeks of sticking with it. Log your results here to see the trend.
Medicines still matter
If your clinician has recommended a statin or other medicine, changing your diet works together with it. Many people need both to reach their goal.
