But is eating a vegan diet actually healthy?
This is a position that Michaels offers with mixed emotions.
She had other health concerns about veganism, as well.

Neither of which are good for you AT ALL," Michaels said.
Her biggest concern is with foods made from soybeans.
Non-fermented soy, however, is bad for your thyroid, Michaels said.

According to Jillian Michaels, menstruation is also a good reason to reconsider your plans to go vegan.
What’s the difference?
So if you are anemic, “this can lead to fatigue and impaired immunity amongst other things.”

Even if you don’t feel tired and weak, we all need our iron, Michaels said.
“Iron is essential for the normal production and function of various cells and hormones.”
There’s a misconception that plant-based foods supply adequate omega 3 fats, Michaels said.

We’re talking dry hair and skin and brittle nails.
That’s because collagen, which supports hair, skin, and nails, comes from animals.
This nutrient has other benefits to the human body as well, including support of the intestinal lining.

Michaels says we still need to eat our vegetables – lots of them!
But, Michaels said, “clean, organic, ethically sourced meat in moderation is ideal.
Birds aren’t the only source of animal protein you should have in your diet, Michaels added.
“Incorporate wild salmon once a week,” she said.
