Ghee's documented side effects come from what it is: almost pure fat, about 60 per cent saturated, at 900 kcal per 100 g. Beyond the 1 to 2 teaspoons a day India's guidelines allow, it adds saturated fat and calories fast, and in trials a ghee-rich diet raised blood cholesterol markers. People with a milk allergy should avoid it. Claims about the stomach, skin and babies mostly have no evidence either way. If you have a medical condition, are pregnant, or take any medication, follow your doctor's advice before changing how much ghee you eat.
At a glance
- USDA FoodData Central lists ghee at 900 kcal, 100 g of fat, 60 g of saturated fat and 300 mg of cholesterol per 100 g.
- ICMR-NIN's 2024 guidelines say "Limit ghee or butter to just 1 to 2 teaspoons/day or avoid, if possible", inside a visible-fat limit of 20 to 50 g a day.
- WHO's 2023 guideline strongly recommends keeping saturated fat to 10 per cent of total energy, about 22 g on a 2,000 kcal diet (200 ÷ 9).
- A four-week crossover trial in 30 healthy adults found a ghee-rich diet raised apolipoprotein B and non-HDL cholesterol compared with olive oil; LDL did not differ significantly.
- PubMed searches for ghee with stomach, skin or allergy terms found no study of those effects from ghee in an ordinary diet; the allergy search returned 0 papers.
What are the side effects of eating too much ghee?
The two on solid ground are extra calories and extra saturated fat. Ghee is almost entirely fat, so a small weight carries a lot of energy, and about 60 per cent of that fat is saturated, the kind ICMR-NIN and WHO ask people to limit for its link to LDL cholesterol and heart disease.
USDA FoodData Central lists clarified butter (ghee) at 900 kcal, 100 g of fat, 60 g of saturated fat and 300 mg of cholesterol per 100 g. ICMR-NIN lists ghee among sources of saturated fatty acids, which it says "are known to increase serum total and LDL-cholesterol levels, increase inflammation, reduce insulin sensitivity and enhance the tendency of clot formation (thrombogenicity) and increase the risk of heart attack and stroke."
How much ghee do ICMR-NIN and WHO say to limit it to?
ICMR-NIN's answer is 1 to 2 teaspoons a day, or none; WHO's is a cap on all saturated fat of 10 per cent of energy. Neither is a target: both are ceilings that ghee shares with every other fat in the day.
The ICMR-NIN Dietary Guidelines for Indians (2024) say: "Limit ghee or butter to just 1 to 2 teaspoons/day or avoid, if possible." They put total visible fat at 20 to 50 g a day depending on energy needs, and call saturated fat use high above "10g/day of visible saturated fats (for a 2000 Kcal diet/ day)" from ghee, butter, palm or coconut oil. Our article on how much ghee per day the ICMR-NIN guidelines allow works the limits through by activity. WHO's 2023 guideline "recommends that adults and children reduce saturated fatty acid intake to 10% of total energy intake (strong recommendation)", about 22 g on 2,000 kcal (200 ÷ 9); WHO's news release on it names ghee among the hard fats where saturated fat is found.
Does ghee raise cholesterol?
The human trials point to a modest rise in some blood lipid markers. They are few, short and small, and the ones on cholesterol were done in healthy people, so they say little about anyone who already has high cholesterol or heart disease.
In a crossover trial of 30 healthy adults in Iran (2022), four weeks on a ghee diet raised fasting apolipoprotein B and non-HDL cholesterol against four weeks on olive oil; the LDL difference did not reach significance. In a randomised trial of 63 healthy young volunteers (2005), eight weeks with ghee at 10 per cent of energy raised total cholesterol, but HDL rose too and the ratio did not change. A 12-week randomised trial of 110 patients with non-alcoholic fatty liver disease (2024) found that swapping daily ghee for rapeseed oil reduced liver steatosis, lipids and weight compared with continuing ghee.

The evidence, concern by concern
"No evidence" below means no human study was found on PubMed, not that the effect is ruled out.
| Concern | What the evidence says | Source and strength |
|---|---|---|
| Calories and weight | 900 kcal per 100 g. WHO advises total fat of 30 per cent of energy or less. | USDA entry; WHO guidance |
| Saturated fat and heart disease | About 60 per cent saturated fat; ICMR-NIN says 1 to 2 teaspoons a day or avoid. | Government and WHO guidelines |
| Blood cholesterol | Ghee-rich diet raised apo B and non-HDL cholesterol against olive oil. | Small randomised trials in healthy adults |
| Milk allergy | Cows' milk is a common allergen; ghee's milk protein was not measured in the one analysis found. | NHS guidance; one laboratory analysis |
| Lactose intolerance | Five ghee samples held under 0.05 to 2.9 mg of lactose per 100 g, against 685 to 688 mg in butter. | One laboratory analysis of 12 samples |
| Stomach upset, acidity, diarrhoea | No study of everyday ghee among 21 PubMed hits; the human studies are of Ayurvedic oleation at large doses. | Absence of evidence |
| Acne or skin problems | No human study of eating ghee among 21 PubMed hits. | Absence of evidence |
| Harm to babies | Lipoid pneumonia in children fed ghee; neonatal tetanus linked to ghee on the cord stump. | Case series of 10; case-control studies |
Can ghee cause stomach problems, acidity or diarrhoea?
We could not find a study that tested ghee in an ordinary diet. A PubMed search for ghee with stomach, digestion, constipation, diarrhoea, acidity or bloating returned 21 papers. The nearest are Ayurvedic studies of internal oleation, in which medicated ghee is drunk in large, escalating doses to prepare a patient for purgation therapy; one such study of 29 subjects set out to standardise the dose and grade the oleation, not to measure everyday digestive comfort.
The one dairy mechanism with good evidence is lactose intolerance, and a UK analysis published in 2015 found between less than 0.05 and 2.9 mg of lactose per 100 g in five ghee samples, against 685 to 688 mg in butter. Our article on whether ghee is lactose free explains why. If symptoms keep returning after meals, the NHS advises seeing a GP rather than cutting foods out on your own.
Is ghee safe for people with a milk allergy?
No one should assume so. Ghee is made from milk, and the NHS lists cows' milk among the most common allergic foods. It says that if you have a food allergy you cannot eat the food you are allergic to, including foods where any ingredient contains it, and that you should not cut foods out without speaking to a GP.
How much milk protein survives clarification is not well documented. The authors of the 2015 UK analysis write that it was "specifically to determine the lactose and galactose content only and not milk protein, although the milk protein content of butter oil and ghee should be lower than butter." Lower is not zero. A PubMed search for ghee with allergy, allergic or anaphylaxis returned 0 papers. Ask your allergy doctor first.
Does ghee cause acne or skin problems?
No evidence shows that eating ghee causes acne, or clears it. A PubMed search for ghee with skin, acne, eczema or dermatitis returned 21 papers on ghee as an ointment base, Ayurvedic case reports where medicated ghee was one step of treatment, laboratory analyses and a home-remedies survey. None tested whether eating ghee, on its own, changes the skin.
What are the side effects of ghee for babies?
Ghee in a baby's food from six months is part of India's complementary-feeding advice; the documented harms involve ghee used in other ways. ICMR-NIN recommends adding "small amounts of nuts, oil seeds, oil/ghee" to complementary foods, and its diet charts for infants of 6 to 12 months list "Oil/ghee 5g" in meals (more in our article on ghee for babies).
Two harms are in the medical literature, both from traditional practices. A 1991 case series from Saudi Arabia described lipoid pneumonia in 10 children given ghee by mouth; eight improved and one died. Case-control studies in Pakistan between 1989 and 1999 found that applying ghee to the umbilical cord stump was associated with neonatal tetanus. These are case reports and associations, not trials. Fat belongs in a baby's food only, and nothing goes on a cord stump without a doctor's or nurse's say-so.
Who should ask a doctor before eating ghee?
Anyone whose condition makes saturated fat, calories or milk a medical matter. The groups below follow from what ICMR-NIN, WHO and the NHS say. None of it is a dosage: your own doctor or dietitian knows your results and medication.
- Heart disease or a history of stroke. ICMR-NIN states that saturated fatty acids increase the risk of heart attack and stroke.
- Raised LDL cholesterol. ICMR-NIN says saturated fat raises total and LDL cholesterol.
- Diabetes, insulin resistance or fatty liver disease. ICMR-NIN lists reduced insulin sensitivity among the effects of saturated fat.
- Milk allergy. Ghee is a milk product.
- Pregnancy, breastfeeding and infants. Follow your doctor's or paediatrician's advice.
Whether the ghee is A2, bilona, buffalo or cow changes none of this: ICMR-NIN and WHO name ghee as a saturated-fat food without distinguishing by milk or method. Himdhara publishes a laboratory report for every batch on its lab reports page before the batch ships.
The short version
Ghee is 900 kcal and 60 g of saturated fat per 100 g, so its real side effects are the calories and saturated fat; small trials found a ghee-rich diet raised some blood lipid markers. ICMR-NIN says 1 to 2 teaspoons a day or none; WHO caps saturated fat at 10 per cent of energy. Milk allergy means avoiding ghee; ghee holds only traces of lactose. Stomach and skin claims have no study of everyday ghee behind them, and the risks to babies come from ghee in the mouth or on the cord stump. Your doctor's advice comes first.
