Dear Student,

These are my opinions on the paper. They might be different from yours.

Questions:

1. What is the main question addressed in this paper?

The main intention is to see whether the substitution of caloric beverages with diet beverages and water will result in greater wait loss over 6 months period as compared to attention control individuals.

2. Why is this important?

This is a simple diet modification step that can be advocated at mass levels to produce modest but cost effective weight reduction.

3. What was the hypothesis that the authors tested?

The author tested two hypotheses

First; participants assigned to the beverage substitution groups would achieve greater weight loss at 6 mo than would participants in the AC group

Second; reduction in caloric beverage consumption, regardless of the replacement type, would result in a greater likelihood of achieving a 5% weight loss than would the control.

4. How was the research question addressed?

a. What was the population studied?

Obese but otherwise healthy older adults of mixed ethnicity consuming ? 280 kcal/d of caloric beverages, were included

b. What was the sample size (sample size = n)?

Total: 318
DB: 105
AC: 105
W: 108

c. What was the setting of the study (clinic, laboratory, ...

Solution Summary

This answer provides critical analysis of a randomized clinical trial testing replacement of caloric beverages with water or diet beverages for weight loss in adults, as a Choose Healthy Options Consciously Everyday intervention.
