If you visit a mechanics garage or a carpenters shop you will likely see a vast array of tools that they use to accomplish the various tasks that they perform. They do not rely on just one "tool" for everything but use a different tool at different times depending on their need. You should learn to look at weight loss supplements as tools to help you lose weight and just like physical tools they all work a little differently and can be used for different reasons and at different times to help you with your weight loss. For instance, thermogenics work best at helping you to burn the existing fat stores on your body so they are good to use in the morning to get your metabolism going or just before workouts to increase the fat burning effect. Thermogenics do not work well late in the day close to bedtime because their stimulant effect will keep most people from being able to sleep properly. A completely different type of supplement for weight loss that prevent harmful calories from entering your body but do nothing to burn existing fat stores are blocker type products. Fat blockers are very useful for the times that you need to block the fat from meals when you are eating meal that contains a lot more fat than you would normally eat on a weight loss diet. Carb blockers will do the same for meals containing high sugar and carbohydrates and work great for reducing the damage from a desert that you just can’t refuse. These are just a few examples of the many weight loss supplement "tools" available to you so learn to use them in the right way and you will make losing weight much easier and more productive for yourself.
