Coconut Oil
Coconut oil gained popularity as a 'healthy fat' but the scientific consensus remains cautious. It raises LDL cholesterol significantly and the American Heart Association advises against its use as a health food. Claims about weight loss and brain health are largely unsubstantiated.
Quick Verdict
Raises LDL cholesterol with no proven health benefits — the 'superfood' reputation is contradicted by clinical evidence and major health authorities.
Coconut oil is fine in small amounts for cooking if you prefer the taste, but don't consume it as a health food. It raises LDL cholesterol and has no proven benefits for weight loss or brain health. EVOO or avocado oil are evidence-backed alternatives.

What It Is
Coconut oil is extracted from the meat of mature coconuts and is composed of approximately 82% saturated fat — higher than butter (63%) or lard (39%). Its saturated fat is predominantly lauric acid (47%), with smaller amounts of myristic acid and capric acid. Unlike long-chain saturated fats, lauric acid has some medium-chain properties, leading to marketing claims that coconut oil behaves like MCT oil. However, true medium-chain triglycerides (C8 and C10) comprise only about 13% of coconut oil. The remainder is metabolized similarly to other saturated fats. Virgin coconut oil also contains polyphenols and vitamin E, which provide some antioxidant activity.
How It Works
The proposed mechanisms for coconut oil's benefits center on its medium-chain fatty acid content. True MCTs (caprylic and capric acid) are absorbed directly into the portal circulation and oxidized rapidly in the liver, potentially increasing energy expenditure and ketone production. However, coconut oil's dominant fatty acid (lauric acid) behaves more like a long-chain fat, being incorporated into chylomicrons and processed through lymphatic transport. For cholesterol, coconut oil raises both LDL and HDL — the HDL increase led to early claims of cardiovascular benefit, but current evidence indicates total LDL increase is the more relevant risk marker. Any thermogenic effects are minimal compared to pure MCT oil.
Evidence by Goal
energy
While MCT oil has modest evidence for increased energy expenditure, coconut oil contains only ~13% true MCTs. Any thermogenic effect is minimal and clinically insignificant for weight management.
weight loss
Meta-analysis shows coconut oil does not produce meaningful weight loss compared to other fats. Marketing claims extrapolate from MCT oil research that doesn't apply to coconut oil's fatty acid profile.
Dosage & Usage
Standard Dose
1-2 tablespoons/day (if used as a cooking fat replacement, not addition)
Loading Protocol
Not applicable
Timing
With meals; commonly used for cooking
Best Form
Virgin coconut oil (cold-pressed, unrefined)
📅 What to Expect
Day 1-7
No clinical evidence for timeline. Contains saturated fat that raises LDL.
Week 2-4
LDL cholesterol likely increasing. No proven health benefit occurring.
Month 1+
Sustained LDL elevation. Major health organizations recommend limiting intake.
Long-term
Replacing coconut oil with unsaturated fats (olive oil) would likely improve cardiovascular risk markers.
🎯 How to Know It's Working
Sustained energy from MCTs
May support ketone production if low-carb
Skin and hair feel moisturized topically
If not working: Most health claims for coconut oil are overstated. If LDL cholesterol rises, reduce intake — it's high in saturated fat.
🏷️ Buying Guide
✓ Look For
- • Virgin cold-pressed coconut oil
- • Organic and unrefined
- • Glass jar (not plastic)
✗ Avoid
- • Refined/deodorized coconut oil (less MCTs)
- • Capsules with unnecessary fillers
🛡️ Safety Profile
Common Side Effects
- • LDL cholesterol increase
- • GI discomfort at high doses
- • caloric density (120 cal/tbsp)
⚠️ Contraindications
- 🚫 familial hypercholesterolemia
- 🚫 established cardiovascular disease (relative)
💊 Drug Interactions
- • cholesterol-lowering medications (may counteract effects)
🔴 Serious Risks
- • significant LDL cholesterol elevation with regular consumption
Long-Term Safety
The primary long-term concern is cardiovascular risk from chronically elevated LDL cholesterol. The American Heart Association's 2017 presidential advisory specifically recommended against coconut oil due to its LDL-raising effects. While populations consuming coconut historically may have different dietary contexts, replacing unsaturated fats with coconut oil worsens cardiovascular risk markers.
👥 Who Benefits Most
Best For
- ✓ those who prefer its taste for cooking (used as fat replacement, not addition)
- ✓ topical skin and hair applications
Less Effective For
- — those with elevated LDL cholesterol
- — anyone seeking weight loss
- — those wanting cardiovascular protection
📚 Key Research
3 peer-reviewed studies supporting this supplement's effects.
Dietary fats and cardiovascular disease: a presidential advisory from the American Heart Association
Sacks FM, Lichtenstein AH, Wu JHY, et al. · Circulation (2017)
AHA advisory concluded coconut oil raises LDL cholesterol similarly to other saturated fats (butter, palm oil) and advised against its use, finding no evidence for claimed cardiovascular benefits.
The effect of coconut oil consumption on cardiovascular risk factors: a systematic review and meta-analysis
Neelakantan N, Seah JYH, van Dam RM · Circulation (2020)
Meta-analysis of 16 clinical trials found coconut oil significantly increased LDL cholesterol compared to non-tropical vegetable oils, with no significant effects on body weight, waist circumference, or glucose.
Coconut oil consumption and cardiovascular risk factors in humans
Eyres L, Eyres MF, Chisholm A, Brown RC · Nutrition Reviews (2016)
Systematic review found clinical evidence does not support popular claims about coconut oil's health benefits, noting LDL-raising effects and lack of evidence for weight loss or cardiovascular protection.
