Sunrise weatherman Sam Mac has shown off his incredible body transformation.

The Channel 7 presenter revealed on Instagram he’d been secretly embarking on a health and fitness journey over the past eight weeks, and the results have left his followers in awe.

Appearing on the cover of Men’s Health with his buff new bod, the 42-year-old said he wanted to “lose his gut” and add muscle to his upper body.

In a candid video posted to his Instagram stories, Mac was seen reacting to the cover, saying, “I’m ripped. I’m absolutely ripped.”

He added, “Oh no, they’ve got the before shot on the cover. I look four months pregnant.”

Mac has unveiled his impressive results after 8 weeks of training on the cover of Men’s Health.

Mac said he attended the Acero gym in Sydney where he underwent regular circuit training, smashing out 75 minute sessions and striving to hit 20,000 steps a day.

Food wise, he cut out his weakness – naan bread – and stuck to a high protein, clean eating diet with plenty of vegetables, clocking in at around 9200 kJ daily.

“I feel like there’s been a marked improvement in my physique, particularly in the last three to four weeks,” he told the publication.

“I was getting leaner in the face, shirts weren’t fitting, I was looking baggy in pants, which was great because that was confirmation for me that the hard work was getting somewhere.

“I feel like I’ve been sharper in terms of my day-to-day mental headspace. I think that’s a by-product of a few things. Physical exercise is obviously great for endorphins and for your whole body. Also, completely cutting out alcohol, cutting out sugars and a lot of the carbs that I would normally have and the heavy, bloaty meals, you feel lighter and you are lighter, physically and mentally.”

Mac, who along with girlfriend Rebecca James welcomed a daughter, Margot, in September, told the publication he often found it hard to stay on-track with his health amid his busy breakfast TV schedule and becoming a first-time dad.

“I think anyone who has entered the world of parenthood will understand that for the first few months you don’t really know who you are, where you are, what day it is. Everything else becomes secondary. Your only priority is your newborn and your partner and that’s all consuming. I was very much lost in that fog, in the best possible way,” he said.

“Naturally, I hadn’t really done a lot of exercise over that time. You’d be eating whatever you could eat, when you could eat.

“When this challenge came along it was a really good time to go, ‘All right, let’s apply myself now. Let’s see if I can get into a better physical shape, which will, in turn, help my mental shape.’”

Mac has been a weather presenter on Sunrise since 2016.

After posting his results on social media, Mac’s followers rushed to the comments section dubbing him, “Sam Jack”.

“Well done mate, Massive effort,” ABC producer Chris Walker wrote.

Former Bachelor turned radio host Matty Johnson posted a series of fire emojis, while Kiwi TV presenter Matty McLean simply wrote, “Oh my.”

Mac said he would be unveiling more details with his followers next week.
