If able, read this transcript. This doctor believes you have to take the drug for ever but no against it.
From it:
”I'm gonna shorten the hundreds of thousands of years, but where I'm going with this, Jonathan, is that we are engineered to maintain our body in times of famine and starvation. So if you go back a hundred thousand years ago when normally you would have times of famine, the body developed adaptive ways to survive when there wasn't enough food around.
So we're very, very good at hibernating, if you will, and surviving without a lot of food. So our bodies adapt. It shuts down. You don't burn as many calories to get through those times when there isn't enough. So fast forward hundreds of thousands of years, and we don't have famine anymore, but our body is biologically engineered that way.
So will, if you go on a diet and you try to lose weight, you could do that. Pretty successfully early on by reducing your calories, as you said earlier, a calorie deficit, so you start losing weight cuz you go into an energy imbalance. However, from a biological point of view, our body thinks that it is famine time or starvation time.
So it goes into this down adaptation to get you through this period. the body is biologically engineered and wired to conspire against you. It does not want to have you lose weight, so it will defend what you weighed before you went on a diet. Interestingly, even though you had excess body fat or excess body weight, the body thinks that's where you ought to be.
So as you lose weight from time zero down, the body fights you, biologically that is, and the. You feel it is, you start getting hungrier as you try to keep your body weight down so food feels and looks more enticing. You're not as content eating the same amount of food you did before, so it drives you to eat more, and it is even more difficult than that.
Your energy expenditure or your resting metabolic rate, the number of calories you burn starts to go down. So you don't need as many calories as you did when you started. And we also now have identified that your muscles become more efficient. So as you're on a treadmill and you know, you're 3.5 for 30 minutes.
You don't burn as many calories cuz your muscles get more efficient in what you're doing. These are all the factors of the mechanisms the body puts into place to try to maintain where you were before and prevent you or make it harder for you to lose more weight. And at some point, individuals start to eat more and changed their diet to what it was and over time, Weight starts to go back up again.
So long-winded answer that. It's very, very difficult to take the weight off and keep the weight off because of the weight. We are biologically wired.”
