Feasting and Fasting

Dw i angen twll newydd yn fy ngwregys.  Dw i'n ceisio 'gwledda ac ymprydio' i golli pwysau. Dw i'n meddwl fy mod i wedi colli tua dwy fodfedd o gwmpas fy nghanol.

I need a new hole in my belt. I'm trying 'feasting and fasting' to lose weight. I think I've lost about two inches around my waist.
