The PWS characteristics of over-eating (hyperphagia) and low muscle tone (hypotonia) mean that weight can be gained very easily by both children and adults with PWS, although in the very early months of life, babies with PWS may struggle to feed and gain weight.  However, with good dietary management and restricting access to food, weight can be kept within normal levels for both children and adults.

The following links are sections from the PWS Journey.  Families can obtain a hard copy of the whole PWS Journey,  which is updated as their child reaches the next age range, by becoming a member of PWSA UK

It includes sections on eating healthily as well as managing the food environment. In the second part there is a range of delicious, healthy, lower calorie recipes which everyone will enjoy.
