Clinical Trial Summary

Over the past century life expectancy has risen rapidly. As a result, the proportion of elderly people continues to grow. Elderly people probably have an impaired regulation of energy balance (energy intake versus energy expenditure) whereby the underlying physiological mechanisms are not fully understood.

The first objective of this study is to provide further evidence for an age-related failure to regulate energy balance in elderly. If the hypothesis of impaired regulation of energy balance in elderly is confirmed then the second objective becomes to elucidate the underlying physiological mechanisms of the age-related failure to regulate energy intake in elderly.

Intervention

Other:
Energy restriction period
The experiment can be divided in 3 phases, namely (1) run-in phase, (2) energy restriction phase and (3) ad libitum food intake phase. Thus, for all participants the experiment consists of three subsequent phases.

Outcome

Type Measure Description Time frame Safety issue
Primary Energy Intake Compensation To assess energy intake compensation, we will assess average energy intake during the ad libitum food intake phase - which is the period after energy restriction- in young men and compare this to average energy intake in older men.
Average energy intake is assessed by measuring total megajoule of energy intake during nine days of the ad lib phase, and then divide it by nine (MJ/day)
Average intake of energy during ad lib phase (9 days) No
Secondary Appetite/Satiety Hormones and Questionnaires Before and after the energy restriction period. No
Secondary Gastrointestinal Function Before and after the energy restriction period No
Secondary Resting Energy Expenditure, Body Composition and Body Weight Before and after the energy restriction period No
Secondary Expression of Genes Involved in Energy Metabolism Before and after the energy restriction period. No
