What This Study Did, in Plain Language
What Was Tested
Researchers studied Copper (Supplement) in this randomized controlled trial publication.
The purpose of this study was to determine the effect of a whole-food protein (cottage cheese, CC) consumed before sleep on next-morning resting energy expenditure (REE), RER and appetite compared with an isoenergetic/isonitrogenous casein protein (CP) supplement and placebo (PL) in active women.
Why It Was Studied
Participants arrived at 18.00 hours for an overnight stay in the laboratory.
At 30-60 min before normal bed time (2 h post standard meal), participants consumed CC, CP or PL before measurement of REE.
Who Took Part
By PubMed's age tags, the people studied were young adults and adults, women only.
How the Study Was Run
In design terms this was a randomized, placebo-controlled and crossover study.
The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.
Some participants received a placebo instead of Copper (Supplement), giving a reference point.
In the crossover set-up each of the participants took both Copper (Supplement) and the comparison in turn, acting as their own control.
What Was Measured
At 30-60 min before normal bed time (2 h post standard meal), participants consumed CC, CP or PL before measurement of REE.
Statistical analyses were conducted using repeated-measures ANOVA (SPSS).
The subject headings attached to it are Anthropometry, Appetite, Body Composition, Caseins, Dietary Proteins, Dietary Supplements and Energy Intake.
Author keywords: CC cottage cheese, CP casein protein, PL placebo, REE resting energy expenditure, TEF thermic effect of food and VAS visual analogue scale.
What This Means in Plain Language
The paper is a randomized, placebo-controlled and crossover study of Copper (Supplement).
The publication is from 2018 (The British journal of nutrition), a journal based in England.

Our Notes on the Compound
Copper (Supplement): The active site of cytochrome c oxidase is described as containing copper ions that are essential for electron transfer.
