Beta-hydroxybutyrate (BHB), is one of the three ketone bodies (energy molecules) your body makes when it's running on fat instead of carbs. It's also known as 3-hydroxybutyric acid or 3-hydroxybutanoic acid (3HB)[*].
The three main ketones your body makes from fatty acids are:
Beta-hydroxybutyrate (BHB). This is the most abundant, making up to 78% of total ketones in the blood[*].
Acetoacetate (AcAc). It makes up around 20% of ketones in the blood.
Acetone. The least abundant, making about 2% of ketones in the blood. It's not used for energy.
Both BHB and acetone are derived from acetoacetate (AcAc), however, BHB is the main ketone used for energy because it's extremely stable and abundant, while acetone is lost through respiration and sweat.
Since one of the physicians knew that cutting food meant better health, that knowledge must have been around long before Cornaro's time and passed down among physicians.
In modern times, scientists discovered that restricting rats' food by 10% or more made them live longer, contrary to expectations. It is counter-intuitive, as one might think that more food means the body can repair itself better, but that's not the case; excess food drives aging faster. Since calorie restriction (CR) is one of the very few interventions that extends lifespan, we'd like to know how it works. If we could discover that, we could intervene in other ways, for example with CR mimetics such as resveratrol.
Many theories have sought to explain CR, e.g.
it results in less fat mass
Less oxidative stress and inflammation
Beneficial changes in the gut microbiome
Lower insulin, growth hormone, and IGF-1
A lower metabolic rate
Less iron accumulation
