Christopher Schwarzenegger began his weight loss journey after being unable to go skydiving

Appearing at the Inaugural Beacher Vitality Happy + Healthy Summit in Los Angeles over the weekend, People magazine reports he said: "It was a big process.

"I started in 2019 when I was living in Australia. I was on this big trip. I made it a big [deal] like, 'Oh, I'm going to go out and do all this stuff, be in Australia,' and I just saw how much my weight was prohibiting me from doing the everyday activities.

"I was like, 'I want to go skydiving.' And my friends were like, 'Yeah, no shot.' I was like, 'Yeah, I can't skydive.' "

Christopher has "tried everything" to lose weight, with his insecurity beginning back in high school, and he still doesn't feel he has reached his goal.

He said: "I tried everything. I was doing meal delivery things in high school, and I remember feeling like a weirdo when I was bringing weird lunches to school.

"It's not an overnight thing, but it took a lot of trial and error.

"And even still to this day ... when you're saying, oh, before and after photos ... I don't feel like I'm an after yet. I don't feel like I'm at the point."

One change which proved effective for Christopher was giving up bread, which he was inspired to do for the 40-day Lent period and was amazed at how much weight he lost as a result.

He said: "Weirdly enough, I gave up bread for Lent. I don't know if anyone's Catholic in here, but I gave up bread for Lent.

"I was like, 'Well, if I'm giving up bread, I might as well just take the opportunity and I'm a good Catholic boy, so I'm not going to break it.'

"And that was my one rule. I was like, 'I'm not going to break Lent.' And so I lost 30 pounds just through that."
