The most common struggle we encounter is that of people that are desparately trying to lose weight. In many cases they have tried every fad diet known to man without success.
One of the constant struggles we hear about is people that have gone on a diet, reached their ideal weight, and then proceeded to pack the pounds back on. That can be a real morale buster.
Many people actually struggle to gain weight. Sometimes there are health reasons why they need to gain but more frequently it is about enhancing their looks through adding muscle.
