The gallbladder concentrates and stores bile as a pear-shaped sac which it can release to help digestion after a fatty meal.
Fad diets are diet programs that gain popularity for a period of time before fading away. The objective of all these fad diet programs is to enable practitioners to lose weight. The diets differ mainly in the period for which they need to be practiced, the size of the meal portions, and the breakup of proteins, fats, and carbohydrates for daily intake. Some fad diets are crash diets that promise desired results at the end of a short and strenuous program whereas others are for a more sustained duration. The success tales with these diets are largely anecdotal and there is a lot of scientific jargon thrown in by those promoting these diets in order to impress prospective weight-loss customers.
