Everyone goes through times when you are not as active as you normally are whether it is because of an injury or because of increased demands from work or family or some other reason. Unfortunately such times are just the reality of life however you do not need to fear that you will gain a lot of weight because such times are a great time to utilize a thermogenic weight loss supplement that increases your metabolism without your having to do anything else. When you are less active you will naturally tend to gain weight because you are no longer burning as many calories during the day even though you are most likely eating the same amount of food. This is a recipe for disaster however you can easily offset your decreased energy expenditure by using a product containing thermogenic ingredients like MaHuang, Guarana or Citrus Aurantium. Whenever you use a true thermogenic you will almost immediately notice that your heart rate increases. Think about what happens when you exercise, your heart rate also increases. In both cases this increase in heart rate means you are burning more calories which is a positive effect for weight loss. Because thermogenic supplements affect your body in a very similar way as exercise they are a great substitute for exercise during those times when you are not able to fully exercise. The next time you are going through a stretch where you are not able to properly exercise enough to avoid gaining weight remember you can use a thermogenic supplement as a substitute to get you through your tough times.
