I don't know if this is available in canada but believe it is in the u.S. My daughter's dr recommends it to patients for many thingsincluding weight loss, dhea (you can check it out on-line at a search engine just type in dhea) also he says take a 30 to 60 minute walk every morning between 6 & 7am (around sun up here but as it's winter there maybe 7 & 8 would be better) of course, after the c-sections, well the dr is male & the c-sections may have left scar tissue that will defeat you no matter what.
Another thing is to make a soup with carrot, tomato, onion, celery & cabbage & you can eat literally as much of this as often as you like it helps burn calories & apparnetly also to lose fluid) & as always drink plenty of water. Grilled fish, grilled (no skin) chicken, cut out bread, pasta, potatoes, butter/margarine - all the usual.
