Brief summary
The purpose of this study is to investigate the metabolic consequences of a moderate weight gain and if the type of dietary fat (saturated versus polyunsaturated) can modify the effects in young healthy adults. Hypothesis: the type of dietary fat can modify the effects of weight gain.
Detailed description
Specific goals: * Investigate if dietary fat composition influences liver fat accumulation and metabolic risk factors in response to moderate weight gain * Investigate if polyunsaturated fat (PUFA) in the diet could counteract any unfavorable metabolic changes that are expected to accompany moderate weight gain * Investigate effects of weight gain and dietary fat composition on markers of vascular health
Interventions
Addition of polyunsaturated fatty acids to the diet in the form of pastries
Addition of saturated fatty acids to the diet in the form of pastries
