- Big Brother winner used to weigh 16st 7lb
- Received Twitter abuse for her size and found dressing stylishly difficult
- Dropped 6st and became fitness trainer
- Now wants to help others beat the bulge through boot camp
- She says fad diets are not the answer
Josie Gibson was recently pictured showing off her bikini body while on a holiday in Morocco.
The 29-year-old is proud of the fact she has lost 6st since she won reality TV show Big Brother in 2010 and has reinvented herself as a fitness guru.
Now she's beaten her own battle with the bulge, she's on a mission to help others get in shape.
Josie told MailOnline the first step on any weightloss journey is realisation - accepting you are not leading a healthy lifestyle and becoming aware of the impact that can have on your day-to-day activities and self-esteem.
She explains: 'There were lots of times I wanted to lose weight in the past - I call them "wake up calls". I think at the start of everyone's weightloss journey it's important to write your wake up calls down and keep them in sight.
'My wake up calls were lots of things but mainly the abuse I was getting on Twitter from people I didn't even know; the time I couldn't do up a pair of knee high boots in plus-size shop Evans and the time I couldn't do a flying lesson my friends had bought me for my birthday due to my size.'
The Bristol-born star said these wake up calls should then become your motivation to change your ways by exercising more and eating less fattening foods.
Participants can book in for a few days midweek, at the weekend or for a full week where they will undertake fitness classes and learn about nutrition.
'The Bootcamp is suitable for women of all shapes, ages and sizes who want to have fun, burn fat and educate themselves on health and fitness. You will leave ready to take on the world,' she said.
Josie, a qualified personal trainer, will lead the sessions which will include military circuits, BoxFit and dance classes.
She describes the boot camp as a "fitness holiday" where she will pass on the knowledge she has gleaned on how to burn fat through exercise and eating well - without yo-yo dieting.
She said: 'I had tried everything to lose weight. All I ever wanted to do was beat my genetics. I've found a way of doing that now and I want to show others the way.
'Changing habits and getting fit is no easy road for a person starting their weight-loss journey. The key to everything is educating yourself, setting realistic goal and loving the person you are.'
She added: 'Forget fad diets! Nine out of 10 people on a fad diet will always end up putting weight on again. The healthiest way to loose weight is to eat natural and clean foods. The environment we live in almost wants us to be sick and fat. We need to make a change together so the food industry changes with us.
Josie said she will give talks on nutrition during the boot camp revealing how her knowledge of food has changed, helping her drop from 16st 7lb at her heaviest to a svelte size 8 now, weighing 10st 2lb.
'I will advise on how I shop for food, eating habits and all the little tips I've learnt along the way to keep fit and healthy,' she said.
'Some people think its all about the amount of calories you eat vs the amount of exercise you do, but it's so much more than that. Some of my friends eat the same things I once did, but will never put the weight on. It boils down to your genetics, what you eat, your environment, how you shop for food, how you feel about yourself, your addictions and all sorts of factors.'
