 What kind of a diet should I be before or after I get any procedure, especially tummy tucks or BBL? You want to be close to your ideal weight as possible. If we're going to use fat to inject it in your breast or in your buttock, I don't want you to lose too much weight. I like you to be within 10, 20% of your ideal body weight. Now, the other question is how long does it last for? A tummy tuck, a BBL, a breast augmentation, it depends how you take care of it. If you're getting a tummy tuck, you want to be on a healthy diet and do 30 minutes of exercise a day just like you should be even without a tummy tuck. If you stay within 5 to 10 pounds of your ideal weight, you'll be fine. It'll last you for a long, long time. As far as BBL, the same thing. BBL is a fat transfer. We're putting the fat in your buttock. If you're super aggressive and like to go to the gym and do a lot of cardio and are looking to lose weight, you're going to lose some of the BBL because it's just fat cells. It's going to shrink the fat cells. On the other hand, if you gain weight, the fat cells are going to enlarge. It's called hypertrophy and you're going to get a bigger BBL. It's all about maintenance with plastic surgery.
