Read the labels and watch the amount of fat and sugar in the ingredients or when cooking. Exercise, but it is mainly what you eat and keeping low on both fat and sugar, you will lose weight. Also eat lots of veges and fruit, all good advice that we live by. Also, skimmed milk if you drink milk. It will be gradual, but does work. Also, alcohol puts on weight, 100 calories in a glass of wine, so best to avoid!!!!
