Regular viewers ofMy 600-lb LifeonTLCknow pretty much what to expect when they tune in for an episode.

For one, how is it that so many people can wind up weighing so much?

Can’t they just stop eating?

Does Dr. Now really care about his patients or does he have ulterior motives?

And what’s the deal with the people who keep bringing patients food?

Dr. Now is just in it for the money

Dr. Younan Nowzaradan, orDr.

Now, as his patients call him, is quite the character onMy 600-lb Life.

In truth, however, Dr. Now often doesn’t make any money for the weight-loss surgeries he performs.

Instead, his commitment to medicine is what guides him.

“We don’t need to be rich.

For one, there’s always a camera around, so people are always watching.

And often, it’s difficult for patients to make the trek just to see the doctor.

That’s not a lot!

So it’s highly doubtful that anyone is making their pain sound worse than it already is.

Once they face their demons, they often find that they can better control their dietary intake.

In every episode, viewers see the patients waking up in the morning and attending to their hygienic needs.

It can get pretty humiliating.

He certainly has an eclectic bedside manner!

But Dr. Now is actually a realpioneer in his field, with a long and successful career in medicine.

Weight loss surgery is a quick fix

Everyone knows that losing weight can be extremely difficult.

But weight loss surgery is no quick fix, something Dr. Now is quick to point out.

Nicole on My 600-lb Life

“They think surgery is the solution for everything.

And it’s not going to change people’s behavior toward food.”

That’s not an easy thing to do!

But regular viewers know that nothing could be farther from the truth.

But is it really possible that childhood trauma can cause someone to eat their way to 600 pounds?

“No one gains massive amounts of weight just because they love to eat,” she wrote.

Kirsten and her daughter on My 600-lb Life

“There is almost always a sad story.”

Especially since they pretty much eat nonstop?

Many of the patients truly don’t realize how bad things have gotten, and it’s fathomable.

Lupe and her partner on My 600-lb Life

That’s why Dr. Now has a custom scale in his office that can weigh up to900 pounds.

Ugh, that sounds horrible!

No wonder she doesn’t want to go back.

And there’s nothing genetic at play either to stop them, right?

It’s actually much more complicated than that, according to an article Dr. Now penned inObesity Help.

“We need to spread the message that obesity is not a patient’s choice,” he wrote.

So there’s a lot more at play than a person’s will-power.

The winner was awarded a cash prize, and of course, the title of The Biggest Loser.

So it’s clear that the techniques used onThe Biggest Loserare drastically different than onMy 600-lb Life.
