Are there any diet pills or appetite suppressants that work and don't have side effects?

Side effects. There are very few, if any, medications that have no side effects. Our bodies are wondrously complex and delicately balanced machines. To tinker with one part using a medication almost always causes additional effects in another part. The goal is to minimize these side effects but they are almost always there to some extent.
Diet pills. There are a constant stream of medications that come to market, both via prescription and over the counter that are promoted to be the biggest, latest, easiest path to the loss of weight. None have ever been shown to be the panacea for the obesity woes in america. Weight loss requires common sense and help with a dietician and an exercise planner.
Foods. Water, organic vegetable broth, green leafy vegetables, natural pickles, apples are great to fill you up so you dont feel hungry and they are very low in calories.
