Consuming eggs for breakfast influences plasma glucose and ghrelin, while reducing energy intake during the next 24 hours in adult men

What Was Tested

The paper reports a study of Ghrelin, published as a randomized controlled trial.

Using a crossover design, 21 men, 20 to 70 years old, consumed 2 isoenergetic test breakfasts, in a random order separated by 1 week.

The macronutrient composition of the test breakfasts were as follows: (EGG, % CHO/fat/protein = 22:55:23) and (BAGEL, % CHO/fat/protein = 72:12:16).

Who Took Part

The abstract describes 21 men taking part.

PubMed indexes the participants as young adults, adults, middle-aged adults and older adults, men only.

After 180 minutes, subjects were given a buffet lunch and asked to eat until satisfied.

How the Study Was Run

The design is described as randomized and crossover.

Because people in this Ghrelin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

In the crossover set-up each of the men took both Ghrelin and the comparison in turn, acting as their own control.

What Was Measured

The macronutrient composition of the test breakfasts were as follows: (EGG, % CHO/fat/protein = 22:55:23) and (BAGEL, % CHO/fat/protein = 72:12:16).

What This Means in Plain Language

The paper is a randomized and crossover study of Ghrelin in 21 men.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 2010 (Nutrition research (New York, N.Y.)), a journal based in United States.
