Yes I agree. It all goes back to ,"The set point theory of weight loss." Some famous scientist found in his Longitudinal weight loss research that many dieters,Not all, but many have a set point for the body's level of weight loss comfort.
If the dieter goes below this range, even by 1 lb it begins a see saw effect or yo yo result in dieting. Long term results were studied, and most dieters who lost weight would usually rebound back to a level of at least what is expected by the Metropolitan Health ht/wt acceptability chart.
So if one was 5'9 and wanted to be 125 lbs forever, eventually, and especially in our 40Something years, and esp for women, they would eventually chunk back up to about 145Lbs. This actually is the acceptable weight for a lady of 5'9.
Therefore, depending on how she lost her weight, either exercise or say bulimia induced, or only fasting and nothing else. One day that woman will inevitably chunk up to a weight that is safe and comfortable for her height and weight, and that's just the theory which i read.
Also, if 1 enters a treatment program to bring their weight up to speed; they may use this type of a ht/wt chart. Therefore if a woman was always at the weight of say 125, but she's 5'9. They would probably ? how she stayed at the low weight of 125 before she became actually diagnosed with an eating disorder(type ?).
Thus they might require a woman to gain enough to weigh at least 145 lbs before medically releasing her. This is because if a female stopped having her menses
for many years, even before becoming diagnosed as actively having an (ED ?); they may require evidence of Return of Menses prior to medical release of patient.
Unfortunately, many med insurance policies may Not cover this length of the ED patient's stay, and may cut off her coverage after 3 months, whether or Not the patient has regained enough to have her menses return.
The remainder of the patient's bills could be $1000's of dollars per month, no longer covered by the health insurance either. The cost would then become, 100% the family's responsibility.
It could even become a court battle
if it were a minor and parents would be responsible in finding a source
to pay this bill while the youth remained in recovery until she chunked up enough for a "medical clearance"....This could be very costly,
much more than braces even.....
1 recovery requirement could be that she regain enough to experience her menses again. For many females this may be at the chart level for wt/height...i.e,(5'9 = 145 and No Less) .
P.S, it's Definitely more costly to put the weight back on in cases of ED's too.....
