absolutely 100% FALSE
there are 300 + pounders in nursing homes who are not given any extra food who don't lose weight
you would think with what the nursing gives them - about 2,000 calories per day that they would lose - you would think that it's not nearly enough calories to maintain a 300+ pound weight
but they don't lose weight - because they're sedentary
it's necessary to be concerned about your metabolism
running or fast walking or aerobics, where you are causing yourself to pant and sweat will increase your metabolism and aid you in losing weight
reducing caloric intake is not enough
unless it is an extreme reduction
and if it is extreme it will be very difficult to keep it up
and very difficult not to revert back to old habits and gain the weight back again
the focus needs to be on both reducing calorie intake and increasing metabolism
foods high in fiber - such as beans and other fresh vegetables make you feel full and can assist in reducing caloric intake
