I Ate 100 Tbsp Of Butter In 30 Days, Here's What Happened

Summary

Dave Asprey describes eating more than 100 tablespoons of butter over 30 days, usually blended into morning coffee with C8 MCT oil. He says he became leaner, had fewer cravings, and received good blood-test results. These are his personal results, not evidence that the approach will work for others.

Strategies and recommendations discussed

• Blend rather than stir: Asprey says to whisk or blend butter into coffee so it emulsifies, rather than leaving a layer of oil on top.
• Choose grass-fed butter: He recommends yellow butter, which he says reflects beta-carotene from grass in the cows’ diet. He claims it provides more vitamin K2, omega-3s, and CLA than pale butter.
• Increase gradually: His suggested schedule is:
  • Week 1: One tablespoon daily.
  • Week 2: Increase to two tablespoons if comfortable.
  • Week 3: Consider three tablespoons if desired.

Adjust the amount to how you feel; he says the goal is not to consume as much as possible.

• Expect possible digestive adjustment: He describes temporary digestive problems when increasing fat intake quickly and says they often settle within several days. He recommends digestive enzymes containing bovine bile and betaine hydrochloride; this is his advice, not a universally established requirement.
• Track your own health rather than relying on his results: Asprey recommends blood tests before and after a 30-day trial. He names fasting triglycerides, LDL, and insulin, and also mentions a coronary artery calcium scan as a measure of calcified plaque.
• Seek medical advice for relevant risks: He says people with heart disease or high cholesterol should consult a doctor, and cautions that the approach may not be suitable for people with an APOE4/4 variant.
• Consider coffee quality: He promotes coffee tested for mold toxins and added minerals, specifically his own Danger Coffee brand.

Claims and evidence discussed

Asprey argues that butter and saturated fat were unfairly blamed for heart disease. He refers to a 2010 review of studies, the PURE study, and the Rotterdam Study’s findings about vitamin K2, while acknowledging that some of the evidence is observational. He also argues that butter coffee can reduce hunger and help people delay meals by affecting insulin and appetite hormones.

These are the presenter’s interpretations and health claims, not established medical advice. Butter contains calories, so drinking it is not a calorie-free fast; the video’s definition of “fasting” is based mainly on its claims about insulin. Anyone considering major dietary changes should discuss them with a qualified clinician.
