$1 Billion! That's the cost to bring 1 drug to market. There are many drugs for many diet-related conditions: High BP High blood sugar Abn lipids etc For a tenth the cost of 1 drug, let's run a definitive trial of a low-carb diet for all these conditions

Dairy fat has unique fatty acids that can be measured in the blood. A big study found these fats associated with 30% reduced risk of diabetes among 63,000 participants. Another blow to the long-standing recommendation to avoid full fat dairy? @Dmozaffarian

Ketones show remarkable promise for heart failure, stimulating interest in ketone supplements. But this requires taking 50 - 100 grams daily. With available products that's many thousand $ a year. On a ketogenic diet, liver can make this amount for free

1972 Study: Subjects with high ketone levels from fasting had NO SYMPTOMS after insulin injection, even with blood sugar DOWN TO 10 MG/DL!!! Authors proposed a ketogenic diet for diabetes. Together with our recent observational study, time for a trial?
