|Would she still look so happy, if she knew that thee treadmill just lied to her?|
The message of today's SuppVersity article is therefore by no means a new one. What's pretty new, though, is the study by V. Bonghana and colleagues from University of Campinas who have compared five predictive equations that are supposed to predict your and everyone else's basal (=excluding physical activity) energy demands (Bonghana. 2013).
"Start with a 15% energy deficit" - based on what?
The above, i.e. to start dieting by consuming ~15% less energy than you usually do, is my usual suggestion for anyone who's not in the "so fat that your health is in danger" zone, someone like you, maybe - someone who wants get rid of his/ her belly to finally see a at least the uppermost portion of his / her abs.

Use the WHO calculation and you are lost

Unless you expend more energy than you eat it is almost impossible to get rid of the belly. Unfortunately, simplistic calories in vs. calories out calculations won't help you find out whether this is the case..
The notion that exercise "alone" can, especially for those who are pretty chubby to begin with, have a "repartitioning effect" may still hold here, but it is more likely that our imaginary post-menopausal training rookie is - if anything - gaining more muscle than fat and that's certainly not going to give her the look she is aspiring. In fact the situation would probably not be much different from the one in the study I had in the Facebook News a couple of days ago (Tibana. 2013).
Adding exercise on top of a proven (your N=1 experience) obesogenic diet rarely helps
In the course of this 8-week intervention study, the subjects, a group of 14 middle-aged (33.9 ± 8.6 years) overweight/obese women (body mass index - BMI 29.6 ± 4.1 kg/m²) underwent 24 sessions (3 times per week) of a whole body RT program with 3 sets of 8–12 repetitions maximum (RM). Unfortunately, for them without any dietary advice / incentive to modify the baseline diets that were obviously to blame for the extra-weight they were carrying.

If you still insist on calculating something, you may also want to take a look at Part III / III of the Female(?) Athlete Triad Series, but please be aware that I am not liable for the damage this type of calorie counting is going to do to your physique and your psyche.
