Fasting- not replenishing the body’s nutrients can
be dangerous. Without food, the body starts to
use its own muscle tissue as an energy source.
Liquid Protein Diet- high protein, low carb liquid
diets can have serious side effects; consult doctor
before using this as your only form of weight
loss.
Diet Pills- burn, block, or flush the fat;
researchers have yet to find a pill that can do this
safely. May help in suppressing energy, but can
have other serious side effects.

from laxatives not allowing digestion or absorption;
Laxatives can also damage composition of blood
