We all know it's very hard to lose weight. This is because our bodies are designed to keep weight on at all costs due to survival. Our DNA decided these things. What has changed is our diet but our genetic blueprint has not. Hence, our bodies are not designed to process the types of food we are fed today. A good analogy would be: It's like putting diesel fuel into a regular car (which doesn't work). Another sad statistic is that less than 6 percent of weight-loss attempts succeed.
