As long as you at least eat your bmr (or close to it) on your low days you should be fine, you may find as some do days after workouts can make one very hungry, so if you plan for a medium or large cal intake days for after big workout days it should help :) Good luck! :D
Yeah- please post an update in a couple of weeks b/c I'm curious to see how that works for you. If it moves the scale faster for you, I may try it myself . Right now I'm being really disciplined with eating about 1200-1300 cals a day (more or less some days) and moderately exercising 3-4 days/wk. The weight is coming off slow 1 lb a week maybe- booooo! ( I'm the big 4-0 though so maybe age has caught up with me). It didn't seem so hard in the past.
Good luck with it!
Sun- 1550/ Latin Grooves 35 min or walking with light weights (free) and abs or Bodyworks (depends on schedule)
Mon- 1439 (cal target per CC, guess that's my BMR)/ 1 hr Zumba with 20 min weights
Tues- 1439/ 1hr Zumba with 20 min weights (different muscle grouping)
Wed- 1721/ 1hr Bodyworks, 20 min weights
Thurs/ 1439/ 1hr Zumba, 20 min weights
Fri- 1500/ 1hr Bodyworks, 20 min weights
Sat- 1900-2000/ rest day
Each day I'll work my abs. My Zumba/ dance days are my hard cardio days and I'm stiill working my muscles (isometrics I believe) and some additional weights. My Bodyworks classes are cardio/ free weights combined. My only exercise that's changed is adding Sunday and now I'm sctively tracking/ planning my low days instead of letting them happen. Also I thought easing in and out of the highest cal day might be better that dropping from 1900 to 1439 but I'll see.
