As a Nutritionist, I get down right pissed off when someone goes into a health food store looking for the next greatest thing in weight loss and the person working there steers them over to the diet section and shows them the lastest craze. Well, that latest craze is two things. Green coffee bean extract and Raspberry ketones. What do these really do for you? SQUAT!!! Don't you fall for the magic pill syndrome!!! They both claim to burn bodyfat, stimulate metabolism, etc. Clinical research has had small results.
Here is the summary below in a nutshell. You can click on the link and read the rest if you wish.
Just as Dr Oz mentioned, understand by adding a single weight loss product such as pure green coffee bean extract will never replace what a quality diet and plenty of fitness can do.
As for raspberry ketones, claims state "when paired with exercise". That's right. Exercise.
BUT....with that being said, you can workout and treadmill yourself to death with maximum effort, but if your nutrition isn't in check - guess what?! - you may, if you're lucky have a minimal 2-3 pound weight loss over a 6 month period. Now, assume the same scenerio but this time you get on a good meal plan (I do those too!) coupled with your workouts of 3-4 times per week, you will more than quadruple your results of up to 15 lbs in the same time frame. Don't believe me? Just do it. I have been weight training on top of following good nutrition habits and with the exception of added muscle from hard core training every now and again, I pretty much weigh the same as I did in high school. It's about making it a lifestyle - plain and simple.
Thanks for listening! XO
