Days 1-4 of the study served as a baseline, during which participants became acclimated to the research unit and received training on study procedures and neurocognitive tasks; ad libitum
cannabis smoking was allowed from 1200 to 2300 each day.
The first feeding group was used as a control (0 (Percent) restriction) and fed ad libitum
throughout the 84-days experimental period.
Survival times (days) of grasshoppers placed in plastic cages with either diatomaceous earth (15 g/ [m.sup.2)] or volcanic ash or without either of these abrasive materials (control) and fed fresh leaves of dandelion (Taraxacum officinale) ad libitum
. A fan was used to simulate wind gusts.
Before the study started, one hundred day-old Hubbard broiler birds purchased from a commercial hatchery were brooded (under electric hoods) for 3 weeks, and fed standard commercial starter diet ad libitum
until 4 weeks of age.
* The sweet grass and ethanol group rats received sweet grass water beverage ad libitum
instead of water for one week.
Animals (n=54) were age-matched and divided into two main groups as follows: AL (n=29) that received food ad libitum
and IF (n=25) that were subjected to intermittent feeding before immunization.
Skov et al., (9) comparing an ad libitum
high-protein diet with a high-carbohydrate diet, found that enhanced satiety was the most important factor in the weight loss.
For E1, nylon bags and a rumen cannulated cow consuming forrage ad libitum
Adult females were infected intrathoracically with 4 [log.sub.10] PFU of VEEV in a 1-[micro]L volume 6-8 days after emergence and incubated at 27[degrees]C for 5 days with 10% sucrose provided ad libitum
. Intrathoracic infection of mosquitoes with VEEV and incubation for 5 days generates saliva titers comparable to those that occur after oral infection (12).
The WHI dietary modification trial provided "a unique opportunity to examine the long-term effects of an ad libitum
low-fat dietary pattern on body weight," and the results do refute the contention that low-fat diets are to blame for the obesity epidemic.
There are at least two ways to insure that weight gain does not occur during exercise: 1) drink only according to thirst (ie, ad libitum
) (73) or 2) use the USATF guidelines, or analogous methods, to estimate hourly sweat losses during exercise and avoid consuming amounts greater than this during endurance exercise events (74).
In a small pilot study, adolescents who consumed an ad libitum
diet consisting mostly of foods with a low-to-moderate glycemic index achieved a mean decrease in fat mass and body mass index (BMI) of 3 kg and 1.3 kg/[m.sup.2] respectively, at 6 months.
