NCT ID NCT07808736

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This randomized crossover study evaluated the acute postprandial metabolic and hydration responses to two standardized lunch meals differing in nutritional quality and environmental footprint in healthy young men. Each participant consumed both meals in separate experimental visits according to a randomized sequence. Postprandial oxygen consumption, carbon dioxide production, respiratory quotient, energy expenditure, diet-induced thermogenesis, substrate oxidation, satiety, and hydration-related outcomes were assessed.
