It's not diarrhea. All liquid food = entirely liquid poop ummm... duh Losing weight is about burning more calories than you eat. That's it. There is no 'secret' unless you are willing to do liposuction or take a maybe-unsafe diet pill. Being healthy is about having a well-rounded diet and eating a variety of healthy foods. For instance, it is important to eat differently colored fruits and veggies, not just always the same or similar ones, because the different colors represent the different nutrients inside them. In fact, I have to say that eating veggies -- along with smaller portion size -- has been the biggest factor in my weight loss. Veggies are filling when you are hungry, are not high in calories but are high in nutrients and have lots of fiber, which keeps a person making regular trips to the bathroom and not being constipated. I snack on veggies instead of potato chips, usually. Take it from someone who just lost their 37th pound. It's hard and sometimes sweaty and takes self-control and restraint.
