Oh, I'm questioning all this because I didn't lose anything this past week even though everything else (diet and exercise) stayed the same. Thanks!
If you haven't had weight loss this week and you have been at the same workout program for 6 weeks it's time for a change, you've hit a plateau. I never do the same exercise every week, I change up my intensity in running, I do intervals, I do hills. On my weight training days, 4x/week, I change my workouts every week by lifting heavier, varying my exercises... IMHO this is what you are needing, a good change of pace.
You can also change your eating habits by doing less calories one day and more the next. This is called zig zagging...
All these things keep your body guessing and helps to lose weight...
Hope this helps and keep us posted on your progress
