Diet and psoriasis, part I: impact of weight loss interventions. Debbaneh M, Millsop JW, Bhatia BK, Koo J, Liao W. J Am Acad Dermatol. 2014 Apr 4. http://www.jaad.org/article/S0190-9622(14)01126-8/abstract
Obesity is thought to be associated with a pro-inflammatory state. The results of several studies suggest that the body mass index may reflect the severity of psoriasis. Evidence is now available that combining weight loss recommendations with medical treatment for psoriasis and arthritic psoriasis can have beneficial effects. The authors review the data available on the effects of low-calorie diets on psoriasis.
The impact of health professionals’ recommendations on weight loss attempts in overweight and obese British adults: a cross-sectional analysis. Jackson SE, Wardle J, Johnson F, Finer N, Beeken RJ. BMJ Open. 2013 Nov 4;3(11):e003693. http://bmjopen.bmj.com/content/3/11/e003693.abstract
The results of this survey on 810 overweight and obese British subjects show that the recommendations and advice of healthcare professionals may have increased the subjects’ incentive to lose weight and change their habits. However, only the minority of these subjects (26%) had received advice from healthcare professionals about losing weight. It is therefore up to these professionals to broach the subject with their patients.
Self-efficacy for overcoming temptations is a better predictor of weight loss than motivation and global self-efficacy: evidence from two prospective studies on overweight/obese women at high risk of breast cancer. Armitage CJ, Wright CL, Parfitt G, Pegington M, Donnelly LS, Harvie MN. Patient Educ Couns. 2014 May;95(2):254-8. http://www.pec-journal.com/article/S0738-3991(14)00050-0/abstract
The results of this study on 1 115 obese and overweight women show that successful weight loss after 6 months of follow-up depended more on these women’s ability to resist the temptation to give up dieting for various reasons (fatigue, moods, stress, pain, holidays, work, hunger, festive occasions, bad weather, lack of time, week-ends, the urge to eat their fill) than on their motivation. Professionals should therefore assess their patients’ staying-power in order to provide extra support to those who need it.
Excess body weight during pregnancy and offspring obesity: potential mechanisms. Paliy O, Piyathilake CJ, Kozyrskyj A, Celep G, Marotta F, Rastmanesh R. Nutrition. 2014 Mar;30(3):245-51. http://www.nutritionjrnl.com/article/S0899-9007(13)00269-4/abstract
Excess weight in women during and after pregnancy may be associated with a risk of obesity in their offspring. The mother’s eating habits, the mode of delivery, the breast milk composition and the effects of these factors on infants’ gut microbiota may all play a role. The mechanisms potentially involved may set up an intergenerational obesity cycle.
Weight loss during 48 months is associated with reduced progression of cartilage T2 relaxation time values: Data from the osteoarthritis initiative. Serebrakian AT, Poulos T, Liebl H, Joseph GB, Lai A, Nevitt MC, Lynch JA, McCulloch CE, Link TM. J Magn Reson Imaging. 2014 Apr 4. http://onlinelibrary.wiley.com/doi/10.1002/jmri.24630/abstract;jsessionid=22B082594551489C9CF2BB824E6430CD.f01t03
62 obese subjects with a risk of knee osteoarthritis whose BWI decreased by 10 % during a period of 48 months and 65 obese subjects whose BWI decreased by less than 3 % were examined. Analysis of the knee cartilage T2 relaxation times suggested that only a weight loss of more than 10 % was associated with a slower rate of degeneration of the knee cartilage matrix.
