Food addiction in adults seeking weight loss treatment. Implications for psychosocial health and weight loss. Burmeister JM1, Hinman N, Koball A, Hoffmann DA, Carels RA. Appetite. 2013 Jan;60(1):103-10. http://www.sciencedirect.com/science/article/pii/S0195666312003844

This study confirms the existence of a relationship between the symptoms of food addiction and psychological stress (such as depression, binge eating, etc.). Food addiction was found to be associated with a decrease in weight loss after 7 weeks of treatment. These symptoms, which are present in 25% of overweight and obese subjects, undermine their efforts to lose weight.  


Psychological benefits of weight loss following behavioural and/or dietary weight loss interventions. A systematic research review. Lasikiewicz N, Myrissa K, Hoyland A, Lawton CL. Appetite. 2014 Jan;72:123-37. http://www.sciencedirect.com/science/article/pii/S0195666313003991

Based on the 36 studies reviewed here, undergoing behavioural and/or dietetic weight loss treatment results in psychological benefits after one year, even without practising physical exercise. In particular, the subjects’ self-esteem, depressive symptoms, body image and quality of life improved. Greater weight loss results in better quality of life.


Liking for high fat foods in patients with Obstructive Sleep Apnoea. Smith SS, Waight C, Doyle G, Rossa KR, Sullivan KA. Appetite. 2014 Jul;78:185-92. http://www.sciencedirect.com/science/article/pii/S0195666313003991  

The severity of Obstructive Sleep Apnea is strongly associated with subjects’ BMI and their gender. However, their eating preferences should also be taken into account, especially a liking for high fat foods and a dislike of high fibre foods, which were found here to be associated with the severity of the subjects’ apnea, regardless of their BMI.


Obesity and epithelial ovarian cancer survival: a systematic review and meta-analysis. Bae HS, Kim HJ, Hong JH, Lee JK, Lee NW, Song JY. J Ovarian Res. 2014 Apr 22;7:41.  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4022349/ (free access)

Based on the 17 cohort studies reviewed here, obesity in adulthood and obesity 5 years after the diagnosis of ovarian cancer are associated with a poor prognosis of survival. However, the BMI at the time of cancer diagnosis cannot be used as the sole prognostic index to survival.


The effect of non-surgical weight loss interventions on urinary incontinence in overweight women: a systematic review and meta-analysis. Vissers D, Neels H, Vermandel A, De Wachter S, Tjalma WA, Wyndaele JJ, Taeymans J.  Obes Rev. 2014 Apr 22.  http://onlinelibrary.wiley.com/doi/10.1111/obr.12170/abstract;jsessionid=7953D8F58DA1466A909549BB6010D7DE.f02t01

Based on this meta-analysis of 6 studies (including 2 352 women in the intervention group), non-surgical weight loss interventions (diet, exercise or several strategies combined) improved urinary incontinence in overweight and obese women. Even a slight weight loss (amounting to 5 to 10 % of the body weight) significantly reduced the episodes of urinary incontinence. The decrease in the abdominal pressure exerted on the pelvic floor does not seem to be the only explanation for this improvement.
