Tiffiny Hall says 80 per cent of weight loss is attributed to nutrition.
It is comforting to know that even the healthiest person still succumbs to cravings, and it is particularly encouraging to hear on the eve of swimsuit season.
Tiffiny Hall, the terrifyingly toned Taekwondo black belt who became famous training on The Biggest Loser, is on a mission to promote healthy eating. But she is realistic.
The only diet I stick to is consistency. Set yourself limits and stay to them ... Every meal is a separate event.
''It's all about not depriving yourself - any sort of deprivation encourages binging,'' Hall says, admitting she does succumb every now and then to a chocolate binge. ''Nothing beats that milk chocolate Cadburys.''
The 28-year-old has just released a new book Tiffiny's Lighten Up Cookbook and gushes as she talks about her favourite recipe inside: raspberry fluff slice.
''Every slice is under 30 calories,'' she says, before confessing that she likes to ''make it naughty'' by dipping each slice into melted chocolate or hundreds and thousands.
''You can eat too clean as well,'' she says.
Tiffiny Hall warns weight watchers to stick to one or two drinks at Christmas.
Hall is proof that it is possible to have abs of steel without giving up everything, as long as you keep your life in balance.
''The trick is not to get hungry. When you're hungry it sets you up for a binge.''
It seems Tiffiny Hall inherited the healthy gene - both of her parents were devoted athletes, her mother one of the first female taekwondo black belts ever and her father an Olympic Taekwondo coach.
''I was born into this culture of health and fitness,'' Hall says. ''My parents were really into health … I was blessed to have it, it was a privilege.''
Hall first became a taekwondo instructor at the age of 12 and by the time she was 24 was showing off her athletic prowess on TV as ''Angel'' in the reboot of Gladiators.
After that show was axed she secured a regular spot on Channel Ten's The Circle and made guest appearances on The Project. Then she was lured to The Biggest Loser.
It was there that the ''Health Ninja'' really got noticed.
Hall's holistic approach to health empowered her contestants to lose weight and also build their self-esteem.
Hall believes people should not be concentrating on their looks and weight but rather focusing on keeping the body functional.

''The only diet I stick to is consistency. Set yourself limits and stay to them,'' she says.
''I don't drink soft drink, I eat naked and I eat three meals and three snacks a day.''
That doesn't mean Hall eats with no clothes on, she chooses to eat food as fresh and pure as possible - think fresh strawberries with just a swig of balsalmic vinegar or brown rice with lean grilled kangaroo.
''It's not eating anything packaged or processed and trying to cook most of your food yourself … Eating naked is not just about looking good, feeling good, it's also about cancer prevention.''
Hall believes ''nude foods'' will ''harmonise your hormones'' and speed up your metabolism while cleansing your body.
Lighten Up is full of simple recipes involving ''nude foods'' while avoiding trans fats - or unsaturated fats - and sugar.
''Sugar is toxic, trans fat is just the devil,'' she says.
Hall substitutes sugar with other sweeteners, such as agave nectar which is derived from the same plant as tequila.
Her recipe for ''delicious'' meringues with mango and kiwi fruit uses one and a half tablespoons of agave nectar rather than hundreds of grams of castor sugar.
''They're ninja meringues,'' she says.
But as the silly season approaches it's hard for most people to avoid fatty, sugary foods and drinks and Hall is mindful of this.
She warns weight watchers to stick to one or two drinks at Christmas parties rather than getting stuck into the tequila.
''Christmas is fantastic but if you're going out, watch your alcohol and always go for fatty foods rather than sugary foods.''
It's a strange concept, being told by a fitness guru to eat fat, but Hall believes sugary foods are ''the ultimate stealthy enemy'', far worse than the alternative.
She stresses again that eating should not be about guilt, and if you do ''surrender'' to the naughty stuff, move on.
''Every meal is a separate event,'' she says.
Exercise is an integral part of Hall's life even though she believes a great physique starts in the kitchen.
In Lighten Up Hall says 80 per cent of weightloss is attributed to nutrition, with just 20 per cent put down to movement, but she believes exercise is still an important part of any weightloss program.
For beginners, she recommends starting out walking every day and then progressing to jogging and then running.
''The most important thing is movement, for at least 30 minutes per day,'' she says.
''It's all about passion and finding the best fitness for you. For me it's martial arts because it's fun and social.''
Hall does at least three black-belt taekwondo classes a week, three strength classes and fits in running around that.
''I believe exercise is addictive, it stimulates your endorphins.''
She ensures she is up exercising by 7am each day ''because it makes me feel better, it's a habit and has become automatic'' and she actually schedules in exercise appointments in her own diary so she feels obliged to work out.
But for now Hall's ''real passion'' has shifted to writing and this cookbook is just the tip of the iceberg.
The journalism graduate has already written two books on weight-loss as well as a novel White Ninja and has been commissioned to write three more novels.
That's what lured her away from the glitz and glam of television.
''[The Biggest Loser] conflicted with my publishing schedule and I'm not one to do anything half-hearted.''
She says the discipline involved in writing is quite different from that needed for her fitness and health regime, but adjusting to that discpline not hard.
''I don't find it like a job - you can't be too disciplined with writing, as long as I keep my mind and body healthy it keeps flowing,'' Hall says.

Slow-cooked lamb shanks
1 tbsp olive oil
4 small lamb shanks
2 tbsp plain flour
3 garlic cloves, crushed
1 small carrot, diced
1 onion, diced
2 tbsp salt-reduced tomato paste
½ cup red wine
400g tin chopped tomatoes
1 cup salt-reduced chicken stock
1 bay leaf
2 sprigs of thyme
¼ cup green olives, pitted and cut into quarters
½ cup parsley leaves
polenta or steamed green vegetables to serve
Heat the oil over a medium-high heat in a heavy-based, lidded pan large enough to fit the shanks. Lightly dust the shanks in flour, then add to the pan and brown well. Remove the shanks from the pan.
Add the garlic, carrot and onion to the pan and cook for two minutes. Add the tomato paste and cook for a further two minutes. Return the shanks to the pan, along with the wine, tomatoes, stock, bay leaf and thyme. Cover with the lid and simmer for two hours or until the meat is falling off the bone.
Remove from the heat and stir in the olives. Garnish with parsley and serve with polenta or steamed green vegetables.
Note: If a layer of oil appears on the surface when you remove the shanks, carefully spoon out as much as you can, then place two pieces of paper towel on top of the sauce and gently remove. This will soak up any excess oil.
Asparagus and ricotta frittata
2 tbsp extra-virgin olive oil
1 onion, finely diced
25g parmesan, grated
2 tbsp flat-leaf parsley, chopped
200g asparagus, trimmed and cut into 5cm lengths
Preheat oven to 180C. Heat the oil in a small, ovenproof frypan over a medium heat. Saute the onion until slightly softened. Allow to cool.
Beat together the eggs, parmesan, parsley and onion. Pour into the frying pan, scatter the asparagus over the top and add spoonfuls of ricotta. Cook on the stovetop until the base sets, approximately four minutes to five minutes. Place the pan in the preheated oven to finish cooking the top, about 10 to 15 minutes.
Spelt pancakes with yoghurt, honey and toasted coconut
4 tbsp shredded coconut
1 cup spelt flour
2 tsp baking powder
pinch of cinnamon
pinch of salt
1 cup buttermilk
1 tbsp extra-virgin olive oil
2 tbsp reduced-fat, unsweetened yoghurt
1 banana, sliced
honey to serve
To toast the coconut, dry fry in a pan over medium heat until just starting to colour. Remove from heat and set aside. Sift the flour, baking powder, cinnamon and salt into a large bowl. In a separate bowl, mix the egg and buttermilk. Pour the wet ingredients into the dry ingredients and gently fold until just combined.
Heat the oil in a frying pan over medium heat. Spoon in two tablespoons of the batter and cook until slightly golden. Turn over and cook through. Repeat with remaining batter. Cover the cooked pancakes with foil to keep them warm.
To serve, stack two or three pancakes on a plate and top with a dollop of yoghurt, a few slices of banana, a teaspoon of coconut and a drizzle of honey.
