Can someone please help?
No generally they do not, but if they arent fed enough the metabolism will burn what fat they have.
Yes.
Nope (unless you're lucky enough to have a strong metabolism) - that product requires 48 hours of "avoiding toxins" beforehand.
Aerobic metabolism
A girl needs about 30 minutes before sex to be hot, then about 30 minutes more for a full relation. You can double this process twice to please her.
It may be that their metabolism has slowed, either with age or has always been slow, or, ironically enough, by not eating enough calories, which can also slow down your metabolism. Everyone's metabolism is so individual so the only real way to answer questions like this is to have your RMR (Resting Metabolic Rate) tested.
T3 and T4 is a hormone from the thyroid gland, which is the metabolism center. Those are the hormones that control how slow or fast your metabolism goes. If there is less T3 and T4, your metabolism goes down because there aren't enough hormones to make it go the normal rate. Vice versa, if you have too much, your metabolism goes faster.
The plant lives as long as there is enough water in it to sustain it's metabolism.
In theory, yes. the human can hold its breath underwater for up to five minutes before suffocation or drowning sets in. However, it is hard enough to hold your breath for five minutes out of water. most people can hold their breath underwater for two or three minutes at the maximum
Yes, as long as you have had enough calories eaten before. Light dinners are very healthy because the body's metabolism starts to act slower at nighttime and can't process lots of food.
That depends on what you mean by out of your system, if you mean no noticable effects it should be 3-4 hours for a fast metabolism. If you mean completely out of your system, such as low enough levels to pass a drug test, it could be anywhere from 1 day to a week, it shouldn't be anymore than a week though.
20 Minutes is enough for normal life style
