561:, so that recruiting them would prove easier than seeking out volunteers in the general population. The original pool of 400 responders was reduced to 36 selectees, of whom 32 would go on to complete the study. The main focus of the study was threefold: set a metabolic baseline for three months, study the physical and mental effects of starvation on the volunteers for six months, and then study the physical and mental effects of different refeeding protocols on them for three months. The participants would first be placed on the three-month baseline diet of 3200 calories after which their calories were reduced to 1800 calories/day while expending 3000 calories in activities such as walking. The final three months were a refeeding period where the volunteers were divided into four groups, each receiving a different caloric intake.

The initial ingredients of the K-ration were procured at a local Minneapolis grocery storeβhard biscuits, dry sausage, hard candy, and chocolate. The final product was different from Keys' original ingredients, but most of Keys' suggestions made it to the final product. The rations weighed only 28 oz (790 g), but provided 3200 calories per day. Though several sources claim the name was unrelated to Keys, many historical references support the claim that the K-ration was indeed named after him. The K-ration became such a success that it was often used for more than temporary sustenance, becoming a major staple of military nutrition.

There was a 22% higher risk of death for each 30 mg/dL (0.78 mmol/L) reduction in serum cholesterol in covariate adjusted Cox regression models (hazard ratio 1.22, 95% confidence interval 1.14 to 1.32; P<0.001). There was no evidence of benefit in the intervention group for coronary atherosclerosis or myocardial infarcts. Systematic review identified five randomized controlled trials for inclusion (n=10β808). In meta-analyses, these cholesterol lowering interventions showed no evidence of benefit on mortality from coronary heart disease (1.13, 0.83 to 1.54) or all cause mortality (1.07, 0.90 to 1.27).
