If you've never worked out you might find it rather strenuous all of a sudden. By keeping on the move around the house, walking places instead of taking the car, using stairs instead of lifts and escalators etc all help. If you like dancing put on a CD and dance away. I find a low fat diet works for me but some prefer a low carbohydrate diet, I lack energy if I don't have enough carbohydrates. When I say diet this is a lifetime diet not a losing weight one.
