For your age you need 1500 calories daily to safely lose weight
. I would recommend a Heart Healthy diet
which is a moderate fat diet
. Moderate fat diet means = use polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats (high fat snack foods, butter, fat spreads) and no trans fats.
