Meet Irish doctor launching her own fitness and lifestyle book despite grueling hospital routine
There are a few essential requirements if you want to carve out a career as an Instagram fitness star.
A body that could stop traffic is imperative - even better if you have a USP like Izabel Goulart's abs or Jen Selter's bum.
So encouraging and exciting to see so many of you getting involved in @sweatybetty #31DaystoFit with me! In case you missed it, for Day 10 I took you through a sweaty at home HIIT workout. Head over to www.sweatybetty.com/31-days-to-fit for the full workout video! Make sure to tag @sweatybetty and @thefoodmedic in all your sweaty selfie pics - we love to see them!

Add some inspirational quotes, a killer collection of Aztec-inspired leggings and some overhead food photography, and you have an even better chance of gaining followers.
Throw in a photograph of a dog, a green juice and a shot of you in lotus position on a shoreline, and you are well on your way to netting a sponsorship deal with a leading antiperspirant brand.
This isn't always enough, though. If you really want to expand your reach on Instagram, it helps if you're young, beautiful and tanned...
Many Instagram "fitspiration" models eventually turn their sideline into a full-time job. After all, it's hard to find the time to take 30 selfies in the gym changing room mirror after a long day doing barbell bent over rows.
Yet it's difficult to draw inspiration from someone who doesn't have to sit at a desk for at least eight hours a day, or walk by the hot chicken roll counter on their way to the fruit and vegetable section.
The 'if I can do it, you can do it' motto has significantly more meaning when the person promoting the lifestyle actually has a life outside of the gym. This is where Dundalk-born Dr Hazel Wallace - aka the Food Medic - comes in.
Day 9 of the #12DaysOfFitmass Hands up if you're still with me?I'm working until 9pm every night this week so I'm finding the workouts from the #12daysOfFitmass really easy to fit in before work because they are all between 20-45 minutes long! Lately my training has taken a step back, and this has been exactly what I needed to get me back training and get me motivated again Get involved on social and let me know you're doing this challenge with me by tagging @thefoodmedic and make sure to use the hashtag #12DaysOfFitmass Workouts from days 1-9 are all available on my YouTube Thank you to everyone who has accepted the challenge - I'm loving your daily selfies!

The 26-year-old health and fitness blogger combines a 116k-strong Instagram following with a career as a junior doctor at University College Hospital in London where she is kept busy working 12-hour shifts (no more excuses for skipping the gym now).
While many fitspiration figures like to quote Hippocrates - "let food be thy medicine" - Dr Wallace has taken the Hippocratic oath.
She's also a qualified personal trainer, an ambassador for Sweaty Betty and the author of a cookbook which comes out in May. The Food Medic has positioned herself as the antidote to the misinformation that is peddled within the diet industry.
"The biggest thing about having a medical background is it allows me to critically analyse papers," she explained recently.
"There's so much online at the moment and you need to know how to pick out the good evidence from the bad."
In a world where a six-pack is often enough to prove your expert credentials, it's certainly refreshing to have a fitness figurehead whose research is as solid as her abdominal muscles.
Dr Wallace has raised the bar (after doing a pull-up on it) and one wonders if her popularity is indicative of a wider trend.
As the clean eating backlash gains ground, will legitimate, bona fide experts replace ubiquitous overnight fitness gurus?
Or is Dr Wallace's white coat merely an accessory to her beauty? Put simply, are her followers more interested in finding out where she bought her sports bra than in what university she gained her degree?
There may be a genuine appetite for expert insight in the health and beauty industry, but the 'young, beautiful and tanned' entry requirements still apply - even if you have letters after your name.
