Okay, thanks, Amy. We turn to our "Gma" health alert. The new study claiming that cutting a small amount of calories from your diet could be beneficial even for adults who are of a healthy weight. Dr. Jennifer Ashton is here to show us what this magic number is. So what exactly does this study say? Cecilia, this, I would file under the category of, yes, every little bit helped. This is the first study even though small down by the nih and looked at normal weight, lean or maybe slightly overweight people, followed them for two years and found that just cutting about 12% of their daily caloric intake which ammed to just 300 calories improved a lot of their cardiovascular risk factors.

You're also board certified in obesity medicine. Who does this apply to? Does it help anybody. The take home point with this is that if you're in the overweight or obese category, of course, you may want to lose a lot but all of our just losing 5% of your starting body weight can really improve things on the inside. If you're improving these markers and risk factors for heart disease it shifts internally. The magic number is 00 calories a day. How do you get there? This is what it looks like. Our summer margarita, a couple of cookies, this portion of potato chip, that bagel without cream cheese is almost 300 This is what it looks looic in general. Read those labels. Don't drink your calories with sugary beverages. Cut those portion sizes. Skip the sauces and veggies. All right. You heard it here first. Thanks, Dr. Ashton.
