Expecting noticeable change in such a short time is crazy. Management of expectations is of utter importance. If your expectations are left unregulated, frustrations will get the best of you.
Losing weight is easy.
However, you don't necessarily need to lose weight at your size. You need to change your body composition = more muscle, less fat. You don't want to become sickly thin.... which is a real possibility if you go about things incorrectly.
The hierarchy of importance as it pertains to you will look something like this:
1. Diet
2. Resistance Training
3. Cardio
With diet, you want to make sure you're getting in plenty of protein. When you don't have much fat to lose and you diet, your body will have the proclivity to 'give up' more muscle than desired. Sure, the scale weight will fall, but you'll be left just a lighter, softer version of your current self. I don't think that's what your after. So adequate protein creates a pool of amino acids in the blood for your body to pull from as needed.... opposed to pulling from existing amino stores (muscle). You'll also want to get in a good bit of healthy fats. Think nuts, natural peanut butter, avocados, fish, fish oil, flax, extra virgin olive oil, etc. This should have come first, but calories are going to be most important. Are you tracking calories? If so, at this stage in the game it's pretty important. You can use something like or . I'd start by setting your cals in the 10-12 per pound range. Again, what comprises those cals (protein, carbs, fats) is critical as well.
With weight training, it's up there in importance for the same reasons that adequate protein is. This is more true than ever for someone in your shoes; that being a female trying to 'tone up' and drop the last few pounds of vanity fat. It sends your body a strong stimulus to maintain muscle while dieting. Remember, diet = calories in < calories out. How should you weight train? I'd focus on something like 3 days per week following a full body routine. Do you have access to a gym? If so, I can provide you with some ideas of what to try.
With cardio, I'd start with 2-3 sessions per week. Doing more probably isn't necessary unless you aren't compliant with your calories. Ya see, cardio, aside from providing a benefit to your cardiorespiratory system, really only serves as a *caloric bank* for your fat loss efforts. The more cardio you do, the more, theoretically you can eat..... as it's all about energy balances. Expend more energy and obviously it creates a bigger cushion (savings account) to use up when eating. However, there's a fine line that must be walked. Too much of anything is bad, especially in your particular situation. I'd start with 2 steady state runs and maybe one tempo/interval run each week. We can discuss that later.
Realize, I'm shooting from the hip here as I don't know much about you beyond what you provided in your original post. Questions, concerns..... let's hear them. Hope this gives you a general idea of what you should be leaning towards in terms of programming.
