OK girl, I'm gonna help here because I want to spread the MS love, and because you sound a lot like I did when I first got here and didn't have a clue and was pretty damn desperate.
So, to establish calories needed to cut: 10 - 12 x your bodyweight in pounds, so 137 x 10-12 = 1370-1644. If I were you, I'd start at the higher number and see what happens, then add cardio later if things slow down - don't jump into doing a bunch of cardio now - just let the diet work first, otherwise you'll be killing yourself later with too much cardio.
Now, ratios - you can choose: P:C:F = 50:30:20, or 45:45:10, or 40:40:20 (which is what I'm on right now), or carb cycling.
There are lots of different versions of carb cycling - I've never rotated carbs, so I can only tell you what I've read here. You should do a search of spatterson's posts to get more info on what she's doing right now. Anyhow:
0.5g CHO per kilogram of bodyweight on low days
2g CHO per kilogram of bodyweight on high days
3 days low, 2 days high, or
2 days low, 3 days high, or
2:2, or
3:1, or
cycle down from the high number to the low number over 3 or 4 days: eg. 170g, 130g, 75g, 30g, then back up, or
high on training days, low on non-training days, etc, etc you get the picture - play with it and see how it goes.
The above g/kg bodyweight seem somewhat low to me, and are lower than spatterson's I think she's doing 150/75, but she also weighs more than you do. She just experimented til she found something she was comfortable with that worked for HER.
Now, if you choose one of those ratios above, and you're on 12x bodyweight in pounds for calories (1644), these are your numbers:
For 50:30:20
50%P: 822 cals = 205.5g
30%C: 493 cals = 123.25g
20%F: 329 cals = 36.5g
For 45:45:10
45%P: 739.8 cals = 185g
45%C: 739.8 cals = 185g
10%F: 164.4 cals = 18.2g
(That one might be hard to stick to, with such low fat)
For 40:40:20
40%P: 657.6 cals = 164.4g
40%C: 657.6 cals = 164.4g
20%F: 328.8 cals = 36.5g
QUOTE VeggieLifterChick: "I know a lot of pros have some whey protein before bed. "
Well, if they do they're silly because whey gets digested too fast for it to really matter - the best thing before bed is slow-digesting protein, such as casein (in cottage cheese) or, well, I don't know anything about fish or meat, but I'm sure they digest much more slowly than whey. So have cottage cheese or fish before bed. And, well, I'm not too clear on this myself, but unless you work out late at night, don't have too many carbs before bed - have fibrous, not starchy carbs.
Your day's total is VERY close to the 40:40:20 ratios here - just up your protein a bit (egg whites) and you'll be fine.
Also, I would try to go more for oatmeal, legumes, sweet potatoes or yams, and brown rice, rather than too much bread. They'll keep you full for longer.
And, when you're ready, I'd probably drop the jam - fructose is apparently not such a good idea when cutting - it fills up liver glycogen stores, then spillage turns into fat - but you need your muscle glycogen stores to be filled up. But please ask someone else about the details of this, because, really, I don't know - this is just what I was told, and I don't know the bio-chemical details of it.
Well, I hope this helps, and good luck!
