Well, as you (prob) know, fat loss is about being in a deficit.
How do you KNOW you are eating between 1600 and 1800 a day? Are you guessing? Are you estimating? Are you eyeballing ANYTHING at all? Do you eat an apple and say, "this is a medium sized apple", and then look up medium apple and put it down as 75 cals? Do you use a spoon or tablespoon to measure out a scoop of peanut butter? Do you pour yourself a glass of milk (or creamer for your coffee) directly into the cup/mug? Do you count splenda cals, and I cant believe its not butter spray?
My point is, you are little already. You are concerned with losing body fat. Your BMR is 1320 cals a day. I used the Harris Benedict activity multiplier of 1.55, which puts you at the higher end of moderately active... I assume you prob have a sedentary job, but i could be wrong-- keep in mind, almost ALL OF US grossly OVERESTIMATE the amount of calories we feel we burn a day, in other words we think we are OWED more food than we really are.So, activity of 1.55 puts your daily avg calories needs (to maintain) at about 2050 cals a day. Keep in mind these are just starting point numbers. In ANY CASE,, if you are 100% sure that the days you eat 1800 you are really eating 1800, than that only gives you a 200 calorie deficit for that day. That's if you are SURE. My point with the whole thing at the beginning is that unless you are WEIGHING your food to the GRAM with a scale, EVERYTHING you put in your mouth, you could be off...... when you only have a 200 cal deficit a day, if you are off even a LITTLE bit, then you are really eating at maintenance, and you wont lose a pound of fat. Even if you are eating 1600 a day, that is only a 400 cal deficit, and if your tablespoon of peanut butter is a little heaping tomorrow, than that 190 cals just turned into 240 without you realizing it, and did you know that little single serving creamer at the gas station coffee counter has 40 calories in it!!?!? Boom!! You are down to a 300 cal deficit. And guess what else? Your medium apple was really a little bigger and in fact had 110 calories in it.....and you accidentally forgot to count the small handful of almonds you took out of the receptionists bowl.....that's about 50 cals right there...assuming it was only one handful.... Do me A favor and check out the link i gave on the previous page, entitled "the Secret to Fat Loss"
Do you understand what im getting at? The smaller you are, the more diligent you have to be. And the bigger your deficit is (PROB) going to have to be. Im sorry. You might need to eat closer to 1400 or 1500 to give yourself a 500 cal a day deficit, which equals (in theory) one pound of fat loss a week.
Don't listen to people who tell you that exercise is 20% of the equation and diet is 80% for fat loss. Diet is everything. Diet is 100%. Training/exercise helps to ensure that you will be happy with your body when you achieve your goal (of course it serves other purposes as well!)
You are also absolutely right to assume that losing fat will help make you faster!! its FREE SPEED!!! The more body fat you drop, the faster you will get without even trying!! Think of your excess body fat as dead weight your bum has to drag along on every run!
Do you have an actual running goal?
A race? A distance? I need more info to help you design a program...
But right off the bat, how long have you been running (this recent spell i mean?-- i dont care if you ran in HS if that was 20 years ago!) When you trained for NY, that was as a walker? using the run/walk method? How many miles do you run per week now?
If you are doing that running group/class than you've already got speed work built in, so don't add any of that! Only more advanced runners have any business doing more than 1 speed workout per week...... you prob wouldn't physiologically benefit from any more. However if you REALLY want to get faster, once you are ready (depending again on your distance goal-- is it short like a 5K or long like a 1/2 or full?) you would prob benefit from lactic acid threshold training, as opposed to sprint/interval/Vo2Max style speed work. It (intervals) seems to be the most popular, but only because the average joe runner doesn't KNOW about threshold training workouts! I can honestly credit threshold training with taking me from a mid pack runner to winning local races.
Anyway, for now keep working on increasing the distance of your long run once a week, and if you can, i highly recommend adding one easy running day, where you run neither far nor fast, but at a relaxed, fun, comfortable, recovery run pace. At the end find time to do slow,isometric stretching, mobility work, and foam rolling. Try to do mobility and foam rolling twice a week-- once after a run, and once on an off day. you MUST take at least one day off a week.... Strength gains are achieved when we are at rest, not while we are working.....
You agreed that strength training is essential, but i don't see that you've placed any focus on it. I recommend get the fat off first (ie focusing on diet/emphasizing strength training more than you are now) and running moderately or doing some other form of moderate cardio. Once the weight is off you can scale back the strength training (just maintenance lift) and focus on the running and training. For now work on increasing your weekly base mileage.
Once again, what are your running goals?
I also sprained my foot during my marathon in October....mile 2 to be exact..... And then i sprained it AGAIN the week before my January marathon...... Its never gonna heal.......
