An intermittently methionine-restricted diet reduces marrow fat accumulation and preserves more bone mass than continuous methionine restriction, according to a recent study from the Johnson Lab published in Aging Biology . Methionine restriction (MR) is known to increase the lifespan of multiple species, with an increase of up to 45% observed in rodents. The believed mechanism behind this benefit is the lowering of the hormone IGF-1. In addition to increasing lifespan, MR ha
