Hi Linda!
I agree with the others' suggestions. I lost my weight so far these past 2 months with the simple credo of eat less, exercise more. As for diets, what works for some may not work for others. You're probably the best judge of what kind of plan could work best for you. Part of the trick of finding that out is going into things with the mindset that this has to become part of your lifestyle, your routine, something that you can adapt to, or that you can make adapt to yourself.
Have you gotten any ideas yet from reading the board of what might be doable for you? Do you see yourself able to perhaps follow a certain plan or are you more comfortable with the idea of basically eating what you want but in lower portions, substitutions, lower-calorie options, etc.?
The great thing about starting slow and with some small changes is that a person can usually adapt to them fairly well and it makes it easier to make more changes later on if need be. You don't have to come out like gangbusters starting day one. Break it all into steps and mini-goals in your mind. Small changes are easier than drastic ones. Losing, for instance, 60 pounds is sort of a goal in the distance but losing, say, 5-10 pounds this month, and then 5-10 more after that and after that seems easier to attain.
Have an inner chat with yourself. Be honest with your mind, your body, your feelings, about what each is willing to do and able to handle. If any of them end up feeling too frustrated or deprived, it's a good sign what you're doing may not be the right thing for you.
