This plan is basically a reduced calorie diet of around 1200 calories a day. 1200 calories is about the LOWEST one should go for safe weight loss. Usually, with eating a low calorie diet, one starts out at a higher calorie level and loses an initial amount of weight, then drops the calories slightly so they start losing again, and so on until they are around goal. 1200 is about the lowest level. Basically, this plan is a low calorie plan, but THEY have chosen the foods for you-so you aren't eating a bunch of junk like fat free cookies for your calories.
The plan is a little low for your current weight, and there is no dairy listed-so while you have enough protein, fruits, and veggies on this plan-you are going to be low in calcium.
I think this plan would work for you if you did the following tweak to it to make it healthier:
~add in 2 servings of skim dairy a day. This can be 1 cup of skim milk, or 1 container of light or fat free yogurt, or 1 serving of lowfat/reduced fat cheese that is under 100 calories a serving. Add them in at whatever meal you are still feeling hungry with...or add them as additional snacks. Just whenever you need to-but add them in. This will bring your calorie level up to around 1350-1400 a day, which is better for your current weight, and will up your calcium intake to a healthier level.
~Make sure that you are getting in some exercise each day. It doesn't have to be super strenuous if you are not normally an exerciser-a walk each day, a yoga or Pilates video, swimming-just MOVE each day.
Let me know how you do.
