Losing weight can be a difficult task - but one 24-year-old has proven that you don't need to go to extremes to shed the kilos.

Claudia Tomczyk, from Adelaide, lost 14.5 kilos and managed to go from a size 12 to a size 8 in just 16 weeks.

Her relationship with food prior to her lifestyle change was damaging, as she would always eat too much.

Although the network marketer wasn't eating bad food, her portion sizes were 'ridiculous' and she would always go up for seconds and thirds.

'It wasn't until the food hit my tummy where I started to feel sick and I would actually experience a lot of pain,' she told FEMAIL.

Her relationship with food prior to her lifestyle change was damaging, as she would always eat too much (left before, right after)

'It was these moments that I would start to feel guilty for eating all that food and I would always regret my decision of going up for more. It was a vicious cycle,' she added.

She had tried for years to 'reach 60 kilos' but it wasn't until she found a nutritional cleansing program that she was finally able to do it.

'What played more on my mind than the number on the scale was the look of my legs,' she said.

'I've never said nice things about my legs because of how big they are. I would focus on the cellulite and the fact I thought they were too short. I would always call them thunder thighs.'

The fitness blogger never thought that it would be possible to transform her pins in the way she has now.

'I thought I just had to accept the fact that those old legs of mine were what I had to deal with for the rest of my life,' she said.

'Little did I know it was possible to change the figure of my legs and my whole entire body.'

Previously Ms Tomczyk had always been into sport and had been fit her whole life.

She said that in the past she never had nice things to say about her legs, she would often refer to them as 'thunder thighs'

During school she played netball, did sport aerobics and competed in several cross country events.

This is what particularly annoyed her about the fact that she wasn't happy with her body and how it was now performing.

The catalyst for her weight loss started two years ago when she got back from a three month trip around Europe.

She enjoyed herself in the way that any young 22-year-old would, eating lots, partying a lot and generally not looking after her body.

'It wasn't until I got home and I looked in the mirror and it hit me. It hit me how much I had let myself blow out. I was just so embarrassed,' she said.

'Some people may say "Claudia, I would love to look like your before photo" and I get that, I have never been obese or super overweight, but for me my before photo was not okay.'

Not only was she unhappy with how she looked on the outside but on the inside she felt even worse.

Ms Tomczyk said she felt sluggish, tired and unhappy and she felt like she had no direction and that she was stuck in a rut.

Ms Tomczyk's exercise routine She wakes up in the mornings and does 20 minutes of some form of cardio. Five days a week she does strength and conditioning based training. This includes a mixture of compound movements with weights, body weight exercises and energy system training. Advertisement

'I still remember that I couldn't sleep for two nights because I was just so anxious of my situation,' she said.

'I cried myself to sleep because that's how I thought I could just forget about it. I didn't even want to go to the gym because I didn't want to look at myself in the mirror.'

Over two weeks she tried to get out of this vicious cycle but she still continued to eat badly once she was home.

Then one night she told herself that 'enough is enough' and that she was going to make a change.

From that point onward she decided to commit to her weight loss goal.

She will occasionally start her day with a smoothie bowl topped with strawberries, desiccated coconut and seeds

Ms Tomczyk likes to meal plan, so she often cooks chicken, beef and fresh vegetables for the week ahead

As a snack she will sometimes prepare a tuna salad which contains tuna, asparagus, tomato, cucumber, almonds, sesame seeds and a teaspoon of whole grain mustard

She enrolled in her first ever 16 week IsaBody Challenge and followed a nutritional cleansing program.

In the first 30 days she lost four kilos and the majority of the weight came off in the first four months.

She completed the challenge four different times to hone and tone her body to create the figure she is happy with today.

Once she lost the weight she decided that she wanted to build lean muscle so started to exercise more.

By the time she entered her third challenge there were no changes on the scale, however she managed to transform her whole body.

This was when her body started to become lean and her abs started to 'pop'.

'It was this challenge where I really wanted to start to help other women to let them realise that they can transform so much physically without the scales showing anything, so my tip is to throw the scales away!' She said.

Ms Tomczyk then decided to started program to encourage women to achieve their fitness and health goals.

Her main piece of advice is for people to stay committed and be consistent, as results don't happen overnight.

She explained that balance is key, which means people need to make a lifestyle change instead of being strict for a couple of weeks before giving up.

'It does take time so you need to visualise your goals. I had my goals posted everywhere in my house,' she said.

'In the end you just got to ask yourself how bad do you want it? Every day is another chance to get stronger, to eat better, to live healthier and to be the best version of you.'
