Garcia, who capped an impressive second half of the 2022 season by winning the WTA Tour title, told L'Equipe she had turned to food to "fill a void" when things were not going her way on court, prompting an outpouring of support from the tennis community.
"I think if I did know it was going that much, maybe I would not have said it," she said,
Garcia will be playing Canada's Katherine Sebov in the Australian Open first round on Tuesday.
"After, when I saw how much it went all around the tennis world, I was feeling a little bit uncomfortable with it.
"I don't regret saying it. It's what happened. I'm not ashamed about it.
"I think it's happening to a lot of athletes and a lot of also regular people because we are still human and we go through a lot of emotion."
Garcia took a break from tennis in March last year to undergo ankle surgery and returned in fine form, winning in Cincinnati, Bad Homburg and Warsaw while also reaching the semi-final of the US Open.
She takes on Sebov hoping to quickly hit her stride as she sets her sights on a first Grand Slam title.
"I think what is tough is we don't have a lot of rhythm," she said. "The Slam is coming very fast after the off-season, so you didn't play.
"You can play tournaments, but if you go all the way, of course, you have a lot of matches. So far I didn't get a lot of rhythm on court, not as many wins as I wanted to give me all the confidence I need."
