The text says: "The concept of body image changes during life affecting individual behaviour (Calado, Lameiras & Rodríguez, 2004), so it cannot be separated from the weight loss".

Please explain this. Another view is that body image is influenced by a number of variables in addition to weight loss. So why the stong statement above?

The text says: "When comparing self-perception data through the initial and final week patient treatment photos, they clearly showed satisfaction verifying their waist loss perception (Fig. 4)."

Nor Fig. 4 or anything else in the results section support this statement in my opinion. Please explain.

..."we assumed that patients discontinued the treatment because they did not get the immediate results in waist loss they expected."

Can you explain this statement?

Has the aim of this study been investigated before? One would expect a very short literature review on this matter. Please tell why this proposed knowledge gap matters.

This paper concludes that "Based on anthropometric outcomes and patient perception of their body image it can be concluded that the waist circumference loss is the parameter that retains obese patients in the weight loss program".

This is a very strong statement, and I have huge problems to see how this conclusion is supported by the data that is presented. Please explain this in detail.
