Objective: Increase of resistin and/or reduction of adiponectin have beenimplicated in the development of insulin resistance followingweight gain. We aimed to study this prospectively in humans.
Design: Prospective and interventional with parallel control group.
Methods: Twelve healthy men and six healthy women (age 26±6.6years) and an age-matched control group were recruited. Subjectsin the intervention group aimed for a bodyweight increase of5–15% by doubling the baseline caloric intake by eatingat least two fast food-based meals a day in combination withadoption of a sedentary lifestyle for 4 weeks.
Results: Bodyweight increased from 67.6±9.1 to 74.0±11kg, P<0.001, by the intervention. Insulin levels increased(before: 27.4±12 pmol/l, after: 53.0±22 pmol/l,P=0.004), while plasma levels of adiponectin (before: 5038±3736ng/ml, after: 6739±7949 ng/ml, P=0.18) and resistin (before:21.8±19 ng/ml, after: 14.4±6.8 ng/ml, P=0.074)remained unchanged by the weight gain and were similar as incontrols. On the other hand, leptin levels increased about threefoldfollowing the intervention (before: 5.7±7.4, after: 16±20ng/ml, P=0.008), and also the inflammatory marker C-reactiveprotein (CRP) increased from 0.34±0.44 to 0.71±0.87mg/l, P=0.03, when two outliers >10 mg/l were disregarded.
Conclusions: Hyperalimentation reduces insulin sensitivity when weight gainof 9% was combined with reduction of exercise. However, thelevels of resistin and adiponectin were unaffected by the intervention,while CRP levels increased within this short time period suggestingthat low-grade inflammation can occur early in the process ofdeveloping a metabolic syndrome.
