Found others with the same problem. It relates to the app update 7.5. The update appears to have affected the calculations. See this link http://community.myfitnesspal.com/en/discussion/10478352/ios-7-5-release-notes-discussion

Thanks. Weight not changed. I don't think the walking/running speed has changed. I've been using MFP for 5 months and the change is so dramatic I wonder if there could be a data glitch if no logical explanation.
