In brief: Low D & testosterone
Both are common in men who are obese.
Vitamin d is needed for calcium absorption in the gut. If this is impaired, the body makes PTH to get calcium from the bone. Fat cells also convert testosterone to estrogen leading to low t. Honestly not sure of B12 connection.

In brief: Yes
Obese people tend to have low vitamin d because they require higher doses to raise their level and they tend to spend less time in the sun with enough skin exposed to make vitamin d.
The hyperparathyroidism is secondary to the vitamin d deficiency because you can not absorb calcium with a low vitamin d so the body will raise the parathyroid level and take calcium from your bones. Take vitamin d.
