Ask whether the paleo diet lowers cholesterol and you’ll hear two confident, opposite answers. One side points to trials where LDL and triglycerides fell. The other points to paleo plates piled with bacon, coconut oil and fatty beef. Both are describing something real, because “paleo” covers very different ways of eating.

This guide summarizes the actual studies on paleo diet cholesterol, converts their results into the mg/dL numbers on your lab report, and uses USDA data to show which paleo foods push saturated fat up or down.

The quick version: In short trials, paleo diets built on lean meat, fish, vegetables, fruit and nuts lowered triglycerides and total or LDL cholesterol and raised HDL slightly. But evidence is small and short-term, and a paleo diet heavy in coconut oil, bacon and fatty meat can exceed 30% of calories from saturated fat, which raises LDL.

Does the paleo diet lower cholesterol?

In most controlled trials, yes, modestly and in the short term. The trials that showed benefits tested a lean version of paleo: lean meat, fish, eggs, vegetables, fruit, root vegetables and nuts, without dairy, grains or added salt. Here’s what they found.

Does the paleo diet lower cholesterol?
Study Who and how long Lipid results (paleo vs comparison)
Jönsson et al., 2009 13 adults with type 2 diabetes; crossover, two 3-month periods vs a diabetes diet Lower triglycerides; HDL +0.08 mmol/L (about +3 mg/dL)
Boers et al., 2014 32 adults with metabolic syndrome; 2 weeks vs a Dutch Health Council diet, designed to keep weight stable Total cholesterol −0.52 mmol/L (about −20 mg/dL); lower triglycerides; systolic BP −9.1 mm Hg
Pastore et al., 2015 20 adults with high cholesterol, no statins; 4 months of an AHA-style diet, then 4 months paleo Paleo lowered total cholesterol, LDL and triglycerides and raised HDL, independent of weight change
Manheimer et al., 2015 (meta-analysis) 4 RCTs, 159 people with metabolic syndrome features; up to 6 months Triglycerides −0.40 mmol/L (about −35 mg/dL); HDL +0.12 mmol/L, not statistically significant
Ghaedi et al., 2019 (meta-analysis) 8 RCTs Lower total cholesterol, LDL and triglycerides, higher HDL; results changed when single studies were removed
Genoni et al., 2020 (observational) 44 long-term paleo followers vs 47 controls Higher blood TMAO, a gut-derived compound linked with heart disease; lower resistant starch intake

Conversions: cholesterol mmol/L × 38.67 = mg/dL; triglycerides mmol/L × 88.57 = mg/dL.

How strong is that evidence?

Promising but thin. A few points keep it in perspective:

  • Tiny, short studies. The largest trial here had 32 people, and several lasted 2 weeks to 4 months. Nobody has tested whether paleo lowers heart attacks or strokes.
  • Weight loss muddies the picture. Paleo trials often produced weight loss, which improves lipids by itself. Boers and Pastore adjusted for weight and still saw benefits, which is encouraging.
  • Order effects. In the Pastore study, everyone did the heart-healthy diet first and paleo second, so time and practice could play a role.
  • The 2019 meta-analysis carries a caution. Its authors said the lipid effects shifted when individual studies were removed, and the journal later published an expression of concern and an erratum, both listed on its PubMed record.

The fair summary: a lean, plant-heavy paleo diet looks at least as good as standard advice for triglycerides and HDL in the short run. Long-term heart outcomes are unknown. Harvard’s paleo diet review reaches a similar cautious conclusion.

Can the paleo diet raise cholesterol?

Yes, depending on what you eat. Eating a lot of foods high in saturated fat raises LDL cholesterol, and the National Heart, Lung, and Blood Institute advises keeping saturated fat to no more than 10% of daily calories. The American Heart Association goes further, to about 7% (Harvard summary).

Popular paleo cooking leans on coconut oil and coconut milk, which are among the most saturated fats in the kitchen. Harvard notes that coconut oil raised total and LDL cholesterol more than unsaturated oils in trials and should not be viewed as a heart-healthy food (Harvard: coconut oil).

The 2020 Genoni study adds a second concern. Long-term paleo followers had higher levels of TMAO and ate much less resistant starch, largely because they skipped whole grains. The authors suggested a variety of fiber sources may be needed for gut and heart health. That’s a reason to eat plenty of vegetables, tubers, fruit and nuts on paleo, not just meat.

Which paleo foods are highest in saturated fat?

Here’s what typical servings of common paleo foods contribute, from USDA data. For context, 10% of a 2,000-calorie diet is about 22 g of saturated fat.

Which paleo foods are highest in saturated fat?
Paleo food (serving) Calories Total fat (g) Saturated fat (g)
Canned coconut milk, ½ cup (113 g) 223 24.1 21.4
Coconut oil, 1 tbsp (13.6 g) 121 13.5 11.2
Ground beef 85/15, 4 oz raw 243 16.9 6.5
Ground beef 90/10, 4 oz raw 199 11.3 4.4
Bacon, 3 slices cooked (24 g) 112 8.4 2.9
Salmon, farmed, 4 oz cooked 233 14.0 2.7
Olive oil, 1 tbsp 119 13.5 1.9
Walnuts, 1 oz 185 18.5 1.7
Egg, 1 large 72 4.8 1.6
Chicken thigh, skinless, 4 oz raw 137 4.7 1.2
Almonds, 1 oz 164 14.2 1.1
Avocado, ⅓ medium (50 g) 80 7.3 1.1
Chicken breast, skinless, 4 oz raw 136 3.0 0.6

Calculated from USDA FoodData Central SR Legacy (FDC IDs 170173, 171412, 171796, 174030, 168322, 175168, 171413, 170187, 171287, 173627, 170567, 171705, 171077).

Half a cup of coconut milk nearly uses up a whole day’s saturated-fat allowance. Olive oil, nuts, avocado and fish, by contrast, are mostly unsaturated fat: a tablespoon of olive oil has about 9.8 g of monounsaturated fat and walnuts about 13.4 g of polyunsaturated fat per ounce.

Two paleo days, two very different cholesterol profiles

To show how much the version of paleo matters, here are two days built only from paleo foods, computed from USDA data.

Two paleo days, two very different cholesterol profiles
Day A: coconut and fatty beef Day B: olive oil and fish
Breakfast 2 eggs and spinach fried in coconut oil, 2 slices bacon 2 eggs and spinach in olive oil, 1 cup blueberries
Lunch 6 oz 85/15 burger patty, avocado, romaine Salmon, sweet potato, kale and avocado bowl with olive oil
Dinner Chicken thigh coconut curry (½ cup coconut milk), sweet potato, broccoli in coconut oil 6 oz chicken breast, broccoli and cauliflower roasted in olive oil
Snack 1 oz almonds, apple 1 oz walnuts, apple
Calories 1,807 1,511
Saturated fat 63 g 14 g
% of calories from saturated fat 31% 8.5%
Fiber 24 g 27 g

Calculated from USDA FoodData Central SR Legacy values for every ingredient by weight.

Both are “paleo.” Day A delivers three times the NHLBI saturated-fat ceiling; Day B sits under it. The cholesterol results in the trials above came from diets much closer to Day B. For bowl recipes built the Day B way, see the paleo bowls guide.

What about eggs and dietary cholesterol?

For most people, dietary cholesterol matters less than saturated fat. Harvard notes that studies show a weak relationship between cholesterol eaten and blood cholesterol, and that about an egg a day was not linked to higher heart disease risk in large studies of nurses, while people with diabetes or heart disease should monitor egg intake (Harvard: cholesterol). More on eggs in are eggs paleo.

How to eat paleo with high cholesterol

If your LDL is already high, these adjustments keep paleo closer to the version that performed well in trials:

  1. Cook with olive or avocado oil, and use coconut oil and coconut milk as occasional flavors rather than daily fats.
  2. Choose lean or skinless proteins most days and eat fatty fish such as salmon or sardines twice a week.
  3. Treat bacon and sausage as garnishes, not the main protein.
  4. Load up on fiber: vegetables, fruit, sweet potatoes, nuts and seeds. The paleo nutrient gaps guide shows how to reach fiber targets without grains.
  5. Consider a modified plan. If you want oats or legumes for their soluble fiber, a Mediterranean-style pattern is a reasonable middle ground; see paleo vs Mediterranean and paleo vs DASH.
  6. Recheck your lipids 8–12 weeks after changing your diet, so you’re judging by your numbers, not the internet’s.

When to talk to your doctor

Talk to your doctor before a major diet change if you take cholesterol or blood pressure medication, have heart disease, diabetes or kidney disease, or have a family history of very high cholesterol. Don’t stop or change a statin or other medication on your own. MedlinePlus explains how high cholesterol is diagnosed and treated. LDL responses to the same diet vary from person to person, and only a blood test shows how yours responds.

Frequently asked questions about paleo diet cholesterol

Does the paleo diet lower cholesterol?

In small, short trials, lean paleo diets lowered triglycerides and often total and LDL cholesterol and raised HDL slightly. A 2015 meta-analysis of four trials found triglycerides fell about 35 mg/dL. These studies were small and brief, and results depend on eating lean proteins, fish, nuts and vegetables rather than saturated fats.

Can paleo raise your LDL cholesterol?

Yes. A paleo diet high in coconut oil, coconut milk, bacon and fatty red meat can get more than 30% of its calories from saturated fat, three times the 10% limit NHLBI advises. Saturated fat raises LDL. Choosing olive oil, fish, poultry and nuts keeps paleo within guidelines.

Is coconut oil bad for cholesterol?

Coconut oil raised total and LDL cholesterol more than unsaturated oils such as olive oil in trials reviewed by Harvard, and about as much as other saturated fats like beef fat. One tablespoon has about 11 g of saturated fat. Use it occasionally for flavor, and cook with olive or avocado oil most days.

Is the paleo diet heart healthy?

It can be, but it isn’t automatically. Short trials show improvements in triglycerides, blood pressure and waist size, but no studies have tested heart attacks or strokes. A lean paleo pattern with fish, poultry, nuts, olive oil and lots of vegetables fits heart-health guidance better than a bacon-and-coconut version.

Why can’t heart-healthy oats be included in a paleo diet?

Paleo excludes all grains, including oats, because grains weren’t part of pre-agricultural diets. That’s a rule of the diet, not a finding that oats harm the heart. Oats’ soluble fiber can help lower LDL, so people focused on cholesterol may prefer a modified paleo or Mediterranean plan that includes them.

Your next step: get a baseline lipid test

Get a lipid panel before you start, eat the olive-oil-and-fish version of paleo for 8–12 weeks, and retest. That tells you more than any study can about how your body responds. For the broader picture, see paleo diet health benefits and the paleo diet guide; if you have diabetes too, read paleo diet for type 2 diabetes.

Consider this general nutrition reading, not a replacement for advice from your doctor or a registered dietitian who knows your health history.
