your not eating enough and your are getting like no protein.
You can't have toned anything without low Body Fat and a good diet and workout plan. I know you want to get in shape fast, and in 4 weeks yeah you could get a little tone and knock of some body fat but you have to decide if you want something more than that, if your in for the long haul. 4 weeks is not enough time for any drastic change, but it is enough time to get your started in the right direction. The key is first getting your diet in shape.
Eat 5-6 meals a day each meal with 1 protein and 1 carb (protein should be lean meats,protein shakes,) Carbs should be no white anything, whole grains, veggies, fruits. Those packages dinners aren't very good for you, switch out the cereal with oatmeal or at least get a better cereal like the kashi go leans, Back to nature, Flax plus, something like that. Also water, lots of it. If you aren't peeing alot, your not drinking enough
Do 5 day cardio, I personally like HITT (there is a whole section here in the forum on that) but if not to a 30-40 min routine to start with of Low intensity. Start a 3 day a week full body strength train, give at least a day between strength training to rest for muscle recovery.
There is lots of info around here to get to the details of this but this is the gist. You have to eat to loss fat. You have to work to lose fat.
