After reaching her goal weight of 75kg, Rebel Wilson has opened up about the reasons for her year of health journey and the strategies she used to get healthy.

The Australian actor, 40, was emotional in an hour-long Instagram Live video where she told fans she had failed to treat herself with love and respect in the past but was on her way to developing self love.

Its hard when I talk about the emotional stuff. Its hard. I can do this, she said, adding Hollywood had in a way typecast her to stay as Fat Amy from the Pitch Perfect films.

I wasnt valuing myself and telling myself negative things. That was hard. Im trying to change those patterns.

It makes me sad sometimes that I didnt value myself enough before all of this to get healthy.
