HEALTHY DIET AND TYPES OF DIETS Flashcards
some types of diets-
meditarian diet- Marinex-gonzalez et al.., 2017= variety, fish, veg- emphasis on healthy diet rather than restriction= sustained steady weight loss-
Shmoerling 2020- short term restrictive diets such as Atkins diet and weight watchers-
successful diets
Not all restraint eaters overeat!
variety diets!= Using SSS to promote healthy eating, having salad after salad will not work-
Pay attention to aspects of your food (detail theory)-
Redden et al., 2008=
135 ppts given jelly beans
one condition you got given detail about jelly beans. ALhtough eating same jelly bean those in condition who got information, enjoyed the taste and enjoyed the task more. DETAIL is key in successful dieting.
NOT JUST DIETS- education, exercise!
social support promotes better dieting success-A meta-analysis by Zhang et al. (2022) found that individuals receiving peer support experienced a significant reduction in weight compared to those receiving usual care, with an average weight loss of 0.78 kg. Additionally, peer support was associated with a significant decrease in Body Mass Index (BMI) levels
promote healthy eating not dieting! Higgins and Gray 1999- a meta analysis on anti dieting- those who promoted healthy diets instead of strict diets- no fluctuations in weight, better psycholigcal outcomes, - no weight re gain! more stable weight
SES concerns-
issues with dieting research-
most research done on WEIRD samples- does not represent population, park et al., 2001- found some cultures found it more difficult to diet because of natural inclination for obesity
Gender bias- more females, more females volunteer-generalising these findings to males not applicable-
set point theory- confounding factor-
lipoprotein
critical analysis for dieting
Dieting research is often complicated by numerous confounding factors that can skew results and limit the generalizability of findings. Individual differences, such as genetic predispositions and hormonal imbalances (e.g., thyroid dysfunction, insulin resistance, or polycystic ovary syndrome), can significantly influence weight loss outcomes, making it difficult to isolate the effects of dietary interventions alone Krauss, 2010).
Psychological barriers, such as emotional eating and stress, also affect adherence to dieting plans, while environmental factors, like access to healthy food and opportunities for physical activity, introduce further variability (Gudzune et al., 2020).
Sleep deprivation disrupts hunger-regulating hormones, such as leptin and ghrelin, and metabolic adaptations from repeated yo-yo dieting can impair future weight loss (Bray & Popkin, 1998;).
Additionally, the influence of medications and gut microbiome imbalances is often overlooked, yet these factors can profoundly alter metabolism and weight regulation (Zhang et al., 2022). These confounding variables highlight the complexity of dieting research and underscore the need for more individualized and controlled studies to produce reliable conclusions.
