With times being what they are, people are both getting heavier and living longer. Solomon et al 2008 took 23 seniors with impaired glucose tolerance. Their base measurements (VO2max, insulin sensitivity, intramyocellular lipid accumulation and body composition) were all measured before the intervention. 78% completed the intervention of a restricted calorie diet and 1 hour a day, 5 days a week for 12 week aerobic activity at ~75% of predicted VO2max. While VO2max, insulin sensitivity and body composition all improved consistently with previously done studies going back decades, the IMCL improved (P <0.05). Even 6 months after the intervention has stopped, the subjects maintained a metabolism, which was using increased fatty acid oxidation.
