Raspberry Ketones for Weight Loss: Is it a Scam?
Raspberry ketones have gained a lot of attention since Dr. Oz began promoting them on his show, going so far as to call them “the number one miracle in a bottle to burn your fat.” Since this supplement was featured on the Dr. Oz Show in 2012, they’ve become one of the fastest selling supplements in the United States.
The supplement is actually a chemical made from red raspberries and goes by many names, including Rubus ideaus, Rubus strigosus and Framboise Rouge. Along with being used as a weight loss supplement, raspberry ketones are also used in food and cosmetics.
So, are raspberry ketones really the secret to weight loss or just another scam? Actually, there’s a lot of scientific evidence behind the supplement and plenty of people report real success using raspberry ketones to promote weight loss. Here’s everything you need to know if you’re thinking about giving it a try yourself.
Raspberry Ketones Review: What is it?
Red raspberry ketones are an antioxidant found naturally in raspberries and they’re responsible for giving raspberries their wonderful aroma. Ketones are actually found in very small amounts in the berry, hence the need to take a supplement with a concentrated amount versus eating the berries fresh. Only 100mg of red raspberry ketone supplements is equal to the amount of ketones found in 90 pounds of fresh raspberries!
How it Works
The ketones found in red raspberries work by regulating a protein in the body known as andiponectin, which is used to regulate your metabolism and allow fat cells to break down more easily when the body needs energy.
Thin people naturally have higher amounts of this hormone and taking the supplement fools the body into thinking it’s slimmer, allowing you to burn fat more effectively. Overweight people, on the other hand, have low levels of this hormone so it becomes very easy for their body to store fat. Adiponectin doesn’t actually get rid of fat cells but instead shrinks them by increasing your metabolism.
Along with boosting weight loss, there are some other benefits you can enjoy while taking raspberry ketone supplements, including improvement to your skin’s elasticity for a more youthful appearance. The anti-inflammatory properties of the supplement help your body respond to insulin to reduce the risk of type 2 diabetes and obesity.
Raspberry Ketones Review: The Science
A few animal studies on red raspberry ketones have already shown promising results. The first study, published in 2005, involved giving the supplement to mice on a high-fat diet for many weeks. The mice were separated into different groups on the same diet with different levels of the supplement, either 0.5%, 1% or 2%. The raspberry ketones, which accounted for 1-2% of the total calories in the diet, reduced fat accumulation and body weight in the livers of the animals after a full 10 weeks.
A second study published 5 years later found that the supplement can improve fat burning and inhibit weight gain in mice on high-fat diets by increasing levels of adiponectin, a hormone that’s produced in the body’s fat cells.
Are Raspberry Ketone Supplements Right for Me?
Red raspberry ketones are completely safe to take and there are no known risks to consuming the supplements. As a natural ingredient in raspberries, these supplements are completely natural. Despite the safety, there are some individuals who should not take raspberry ketone supplements because of their effect on the body’s release on hormones. In general, people with asthma, COPD, hypertension, heart problems and diabetes should avoid the supplement until they speak with their doctor.
Raspberry Ketones Review: How To Take
While the supplements are designed to boost your body’s natural fat burning process, it’s still recommended that you use them as part of a healthy diet and exercise program to see the greatest benefit.
It’s important to select a product that uses high quality 100% pure raspberry ketones, which may be more expensive but offer the safest and most effective results. The recommended dose is a single 100mg capsule before your first meal of the day, increased to 2 to 3 capsules as needed. Don’t expect to lose 30 or 40 pounds in a month, either; a realistic amount of weight loss using raspberry ketones, exercise and diet is between 2 and 5 pounds per week.
The Bottom Line
Raspberry ketone supplements are entirely safe to use and actually offer a range of benefits, most notably increased metabolism for improved weight loss efforts. As long as you use them with realistic expectations and combine the supplement with a sensible diet, raspberry ketones can be an effective and simple way to increase the amount of fat you burn and see real weight loss in a matter of a week or two. Just make sure you select 100% natural raspberry ketone supplements, not a cheap alternative that won’t offer the same results.
