Blood Test have any value during NLP?

[Daniel Town]

Do Blood tests have any value when gaining a lot of weight during the NLP? By blood tests I'm referring to the usual check-up (tests for organ functions). I'm assuming some of the tests would come back abnormal since the person is eating a considerable amount to gain weight? would this be okay since the weight gain period is only for a time.

Depends on the person and what's going on. For a healthy young adult probably not necessary. For an insulin resistant mid life or older adult could be useful. Checking testosterone is never a bad idea though.
