For years, raspberry ketones have been among the best-kept secrets in the diet world. However, now that increasing research has confirmed the efficacy and safety of these ingredients, raspberry ketones are becoming part of many mainstream dietary supplements. Whether sold as stand-alone supplements or just as part of a comprehensive fat-burning formula, raspberry ketones can accelerate weight and fat loss efforts when paired with a reduced-calorie diet and an increase in daily activity. As with any supplement, you should consult your doctor prior to using raspberry ketone products. Additionally, visit your doctor before beginning any exercise or weight loss routine.
Although raspberry ketones are a relatively new entrant into the supplement world, other industries have made use of these ingredients for coloring and flavoring in products ranging from foods to cosmetics. But when used in supplements, raspberry ketones appear quite effective; according to a study from the May 2005 edition of the journal “Life Sciences,” consumption of raspberry ketones promotes an increase in the amount of fat your body releases and burns for energy during exercise. This means that your workouts will be more effective for slimming down, and you may also feel more energized, as fat contains more than double the amount of energy (as measured in calories) than protein and carbohydrates contain.
Using fat as fuel for exercise is not only beneficial for trimming your love handles, but it can also help you hang on to muscle tissue. Raspberry ketones products have become popular with bodybuilders because the increased fat burning discourages the breaking down of muscle tissues to fuel exercise sessions. Increased fat loss and improved maintenance of muscle tissue are primary goals of bodybuilders, so raspberry ketones products are obvious choices.
But you don’t have to be a bodybuilder to appreciate raspberry ketones’ muscle-sparing characteristics. Increased muscle mass is beneficial for everyone looking to burn fat, regardless of whether or not you want bulging biceps. Muscle tissue burns more calories than fat tissue, so even if you’re not exercising, having more muscle will result in a higher metabolic rate throughout the day. A higher metabolic rate translates into more calories burned and thus, a slimmer you.
The good news is that this metabolic boost is just one part of raspberry ketones’ assault on body fat. The primary mechanism of action for raspberry ketones is a result of their ability to influence the enzyme lipase. Lipase helps break down fat cells, so the increase in lipase activity resulting from raspberry ketones results in a greater amount of fat cells being broken down and burned to fuel your daily activities and exercise sessions. If you don’t engage in weight training or have high levels of muscle mass to begin with, this mode of operation is likely to be the more effective mechanism for improving body composition.
