I read the header, and was about to go off on you, until I read the body of your post.
Back in the 'good old days', such as they were. A soldier who didn't make the physical weight requirements might find himself assigned to the 'motivational platoon'.
There they would find a TS who would ensure their meeting the weight requirements in due time.
Today the motivational platoons have been phased out.
We have the finest technology available, good training, and a large number of our forces who are not able to endure combat, because they're out of shape.
