If you knew anything at all about university & attending same on a hill you would comprehend without my spelling it out that she has to run up & down the hill & stairs to get to lectures on time (mondays 7 1/2 hours of them starting at the bottom then the top then bottom then top etc of the hill all day no breaks at all beteen!!) - you try doing that plus alot of other walking(yes walking - but she walks fast at any time) to various places & see if you can manage it & still not call it a cardio work out.
Her diet I stated that she had ibs & can not eat fast food (if you knew anything about ibs you'd know that her diet can not include pasta, rice, bread, cakes, biscuiits, sugars, sauces, potato, sweet potato, corn etc etc etc so her her diet is not a matter of cutting back on fiood (she eats normal healthy amounts) it's simply a matter that she can not eat garbage or fattening foods including fats!!
She does more cardio & more general exercise & eats more healthily than 98% of people yet she gains weight - because she almost certainly hsa some othr problem (medical) - wehich is not to say that the same applies to others.
I suggest you get a life!!
