Experimental: Alternating energy intake schedule
To alternate between caloric overconsumption and caloric underconsumption from day-to-day
|
To alternate between caloric overconsumption (130% of usual total energy needs) and caloric underconsumption (70% of usual total energy needs) on a daily basis for 6 days/week followed by one ad libitum day for 4 weeks.
|
|
Aktiver Komparator: Regular energy intake schedule
To consume the usual energy intake on a daily basis
|
To consume the usual energy intake (100% of total energy needs) on a daily basis for 6 days/week, also followed by one ad libitum day for 4 weeks.
