Hittade följande när jag sökte litteratur. Om någon vill översätta får dom gärna göra det, min engelska är så taskig så jag klarar mig själv men det ska inte spridas vidare. Men tydligen lyckas vissa gå upp +6 kg och andra gå ner 8 under jul och nyår. Culturella matvanor spelar tydligen en roll?!?!?
Tyckte ivarjefall rubriken var lite kul och villedela med mig.

The Christmas factor in obesity therapy.

Andersson I, Rossner S.

Obesity Unit and Health Behaviour Research, Karolinska Hospital, Stockholm, Sweden.

The effect of Christmas time on body weight development was measured in 46 obese patients in maintenance therapy at the Obesity Unit of the Karolinska Hospital and in 76 hospital staff controls of similar sex and age distribution. In controls a statistically significant weight increase of 0.4 +/- 0.8 (s.d.) kg (P < 0.001) was found, whereas the mean increase in the obese patients of 0.6 +/- 2.4 kg was not statistically significant. Little variation in weight development over Christmas was found in controls, whereas the weight change in the obese group ranged from +6.1 to -8.8 kg over the 2-3 weeks. Seasonal variation in body weight has been attributed to circadian rhythms. Cultural food habits may also play a role.
