Holly Carpenter is planning to put her health food knowledge to the test by signing up to a nutrition course.
The Dublin model is on a mission to prove that looking and feeling good can be achieved with hard work.
The 22-year-old hit out at the super-skinny models who she feels give unrealistic expectations that you can eat what you want and still look good.
"I'm sick of it," Holly told the Diary. "You see these girls backstage at London Fashion Week, tweeting pictures of themselves with giant Big Macs and pretending to be taking a big bite out of them.
"I would rather be an honest role model instead of me saying that I can eat whatever I want because I can't. Then there are girls who can and that's fair enough.
"I have received so many emails from girls who say, 'You are so inspirational and you are making me realise that I don't have to starve myself to be fit and skinny'," added the Britain and Ireland's Next Top Model finalist who also has her own health and fitness blog.
"I would like to do a nutrition course and learn more about it," she explained.
Holly will be following in the footsteps of former Miss World Rosanna Davison in learning about healthy eating after the Dublin model qualified as a nutritional therapist earlier this month. Roz Purcell has also said she has no interest in gorging on a burger and is currently training for an Ironman challenge after setting up her own blog.
Holly is an advocate of the Paleo or 'caveman' diet that favours foods available in prehistoric times, such as meat, fish, nuts, vegetables.
The girlfriend of rugby star Cian Healy also works out six days a week and is enjoying the results, both physically and in terms of the good feedback to her blog.
One of Holly's biggest recommendations is protein butter, which she gets from Bodyfirst in Clontarf, the shop owned by ex-'Big Brother' star Ray Shah.
And the Raheny native has another secret weapon in her Leinster and Ireland prop boyfriend, who is a dab hand in the kitchen.
"I cook for him sometimes, but Cian cooks for me a lot and he makes delicious, healthy meals," Holly said.
The model and health guru has said that her profile has been boosted across the water, thanks to her stint on 'Britain and Ireland's Next Top Model'.
"I was recognised on the tube; when you leave Ireland you never expect that so it's really cool," Holly told the Diary. "I'm just working away with Andrea Roche models right now, but I love working here.
"I would like to travel over to London and check out what's over there, but we'll see," she added.
