The Bridesmaids star explained that at the beginning of 2020, she decided she was going to make this her “Year Of Health”.

“For the last few years I’ve been theming my years, so I had the Year Of Fun, last year I had the Year Of Love and this year I’m like, ‘It’s going to be the Year Of Health,’” she told Drew Barrymore on The Drew Barrymore Show.

The actor went on to say that turning 40 in March last year had inspired her to rethink her health regime.

“I never really focused on my health, which was probably obvious,” she added.

“I was going all around the world, jet-setting everywhere and eating a ton of sugar,” Wilson continued. “That was my vice. I have a very sweet tooth. I love desserts.”
