How to zig zag cals properly/caloric cycling properly

well lets look at common sense here shall we?

1) You are not exceptionally short, yes you are a little on the short side, so you would need to stick above the min of 1200 cals a day unless you metabolic rate was exceptionally low which can be easily remedied with eating more and exercising more.
2) You are at a healthy weight for your height already, 5ft2 and 135 is a healthy range already.
3) You do not have a lot of fat to shed, you are most likely around that 20% range right now. This link gives a closer idea as to what the ideal weights are for women given their height: http://www.annecollins.com/weight-loss/ideal-weight-women.htm 4
4) At your height you should be focused on body composition more than what the scale says so that would mean getting bodyfat measurements, not scale weights. You can be a much healthier leaner, happier you at a heavier scale measurement than what you think is a good number. So without bodyfat % factoring into the equation here there is no way to accurately tell what your ideal weight should be.

This is not intended to be harsh or mean to you but if you feel that you need to be lighter on the scale than you already are then you need to reexamine what a healthy weight means to you. I find that ppl tend to be to worried about the bloody scale number and less about true health. For instance here are my current stats: 5ft8" 166.2 lbs, I am 15% bodyfat, my ideal weight in theory is around 165, but in truth once I am done with my body transformation I will most likely be 175 and 10% bodyfat. My first goal is to shed bodyfat, not get to a set weight. The second is to add muscle to get to where I am totally happy with how I look. I like how I look now but I want to truly love how I look and I am always altering goals around that.

You sound like a sensible person, allow me to alleviate some of your bmi concerns, the bmi scale is worthless, literally as it takes nothing into account for lean muscle mass or bodyfat, a bodybuilder will register as obese on the BMI scale, hell I show as overweight on the BMI scale and I am far from that. You need to shift focus from BMI to body fat % the reason being that it is a better means of determining health. It is not perfect but it is a far cry better than BMI. To determine what you would be happiest at is to look at how far you have come, you have dropped 110 pounds which is a fantastic achievement. The question you need to ask is do you think that losing more is maintainable given your current lifestyle. Do you want to live like a hermit to maintain a super low bodyfat? I can assure you that getting super lean is not easy by any means, we all need to live and its a matter of how far you want to take it vs the lifestyle to maintain that weight. At some point you need to strike a balance and learn to live with that choice, for 85% of the population they will be happy at the sensible easily maintainable bodyfat% 25% or so for women and 20% or so for men. I am pushing it further simply to prove to myself that it can be done, whether or not I choose to keep it long term will be a function of how busy my life gets. I want to be healthy and if that means being a higher body fat than my current goal then I am ok with that choice.
