Dietary patterns and fatigue in female slimmers

Abstract

Purpose This paper aims to understand the association of dietary patterns with perceived fatigue and identify predictors for presence of fatigue in women who are obese and trying to lose weight. Design/methodology/approach An online survey, hosted by slimming world (SW), comprised of a questionnaire regarding weight, level of fatigue and food frequency questionnaire before joining the weight management programme (T0) and current data (T1) was conducted. In total, 543 non-pregnant women with obesity of child-bearing age (19-49 years) completed the survey (T0-T1). The principal components analysis was used to determine dietary patterns and multinomial logistic regression was used to analyse predictors for presence of fatigue. Findings The participants who have a “simple carbohydrate and high fat” dietary pattern were more likely to have fatigue at T0 (p ≤ 0.001) and those who followed a “vegetables” dietary pattern were less likely to have fatigue at T1 (p ≤ 0.05). The study findings indicate that while “simple carbohydrate and high fat” dietary pattern was associated with increased risk of fatigue, “vegetables” dietary pattern was associated with reduced risk of fatigue and a higher percentage of weight loss. Originality/value The present study appears to be the first study to examine associations between dietary patterns and fatigue. The strengths of the study included the in-depth analysis of this association in both before joining a weight management programme (SW) and currently as a member of SW with an adequate sample size.

“…For weightlifters in the midst of weight loss, high protein consumption helped with fatigue [56]. For non-athletes losing weight, higher vegetable consumption was associated with lower levels of fatigue [57].…”

Curiosities of Weight Loss Diets of the Last 60 Years

“…In 1969, a company in the UK, led by group facilitators known as consultants, implemented an eating plan that incorporated principles of food satiety and energy density. Participants were encouraged to consume lower energy-dense foods in unlimited quantities while maintaining controlled portions of higher energy-dense foods [39]. Coe et al [40] noted that individuals were assisted in making positive behavioral changes to support weight loss and sustain long-term weight loss maintenance.…”
