This is all thanks to Joe Wicks, the online nutrition coach and creator of the 90 Day SSS Plan, who goes by the alias The Body Coach. With 300 clients signing up to his account every day and four book deals under his belt, he's something of a fitness force.
So what exactly does he put on his plate? Notebooks at the ready...
How did you make it 'big'?
My rise on social media seems like an overnight success but it’s really taken two years of hard work and persistence. It takes a long time to build trust with people. I did that with over 20,000 tweets and 2,000 Instagram videos. Momentum has picked up this year but there was a lot of time with no one listening – if you shout loud enough eventually people will hear you!
Are there any foods you had to teach yourself to love?
I didn’t eat fish for 25 years but when I realised how important Omega 3 and protein was for me, I started to introduce it into my diet. Now I eat prawns, salmon and sea bass for breakfast, lunch or dinner!
What's the weirdest thing in your fridge?
Pickled gherkins – you either love them or hate them.
Have you ever made something that tasted gross?
Definitely, I’ve made some shockers in my life. Recently I made a salad dressing that caused me to physically gag. I'd poured it all over my salad so I was in a bad mood for the rest of the day. That said, I had to make mistakes to stumble across some new, great recipes and most of the time, it works.
What's your girlfriend's favourite meal?
My Thai green curry with prawns.
What's the funniest proposition you've had on instagram?
Well, I get about 10 girls and a couple of guys asking me to marry them most weeks, so it's hard to choose.
What's your ultimate 'get fit' tip?
Do HIIT Cardio - bursts of quick, controlled movements - and some weight training over steady state cardio (like a long run). It burns fat fast and builds lean muscle.
What's a healthy snack we should all take to work?
Homemade guacamole with vegetable sticks like celery, carrot or cucumber. Avocados are a super food.
Tell us about your day on a plate...
It starts with my protein pancakes after a 20 minute HIIT session (my reward), then I follow up with a chicken and quinoa salad for lunch and end my day with grilled sea bass and mixed vegetables for dinner. I never forget dessert. A bowl of ice cream and a movie is essential for winding down.
What takeaway do you like?
I do like a big Mexican burrito from Waterloo Station on the way home from a big night out!
What's the biggest diet myth you've ever heard?
Eating carbs after 6pm makes you fat. Complete myth. So if you do train in the evening, don’t forget to refuel afterwards with a nice big plate of carbohydrates and protein. There are also a lot of myths around juicing like they're packed with sugar. If you make a really tasty green juice at home with spinach, celery and a bit of sweetness from one apple, you can bypass any sugar that you'll find in shop bought juices.
What's one piece of advice you would've given your younger self?
Don’t worry so much in your early 20s because by the time you hit 30 none of that will matter. Enjoy yourself, work hard and be nice to people.
