Hi Suzy! Welcome back
My suggestion would be to take it one step at a time.....commit yourself to making a lifestyle change, not a restrictive short-term diet that will come back to haunt your waistline. Losing weight depends mostly on what you eat, so diet is definitely important - maybe you can start by getting that unhealthy stuff out of the house! There are lots of recipes available on this site, as well as many others, that you can use to cook healthier meals.
