How Many Calories Do You Eat? (Weight Loss)

[michelem]

From what I understand, BIA isn't as accurate as the underwater method.

Seems like it's harder to prepare too:

No food or liquid 4 hours before test
No exercise for 12 hours prior to test
Urinate completely before test
No alcohol for 48 hours prior to test
Test at the same time of day (first thing in the morning is recommended after drinking one glass of water)
