A biohacking mum spends up to £2k-a-month to stay young - and says she is mistaken for her 18-year-old's sister thanks to oxygen chambers and light therapy.

Tracy Kiss, 38, transformed her life after feeling like she looked like an "80-year-old" and "burned out" when she was just 25."

The single mum-of-two was suffering aches and pains, and couldn't walk without feeling faint.

She upped her calories to over 3,000 a day, and started weight training daily.

After some wellbeing and aesthetics courses, Tracy turned to biohacking - and switched 12 years of using fillers and Botox for blood filtration, oxygen chambers, and light therapy.

She claims it has made her feel youthful and she's always being ID'd for alcohol and mistaken for her 18-year-old daughter's sister.

She spends up to £2,000 a month on her treatments, averaging £1,000 a month.

Tracy, a content creator from High Wycombe, Buckinghamshire, said: "Biohacking is like being reborn."

"I renew my cells so I look naturally young."

"To be honest self love was the key."

"I don't want to brag, I just want to be the change I'd like to see."

"A lot of beauty is about airbrushing, but I've fixed my ageing from the roots, so I just glow naturally."

"And I'm really strong. I can hike mountains, lift weights, climb trees, and do pullups and flip overs on the side of my house."

"A lot of my friends my age get told they look about 43, but I get ID'd. It's very funny."

"People are always really surprised when they realise I'm my daughter's mum."

"I realised my lifestyle was winning when I could carry a grown man on my shoulders and beat him in running races, he'd be exhausted and I'd have so much energy."

"Age 25 I was totally burned out."

"I was mentally, physically, and emotionally broken. I needed to get back on my feet, I had two children to look after."

"Biohacking makes your age really just a number. My age in years bears no relation to the age of my cells."

Tracy started to get burnout after the birth of her son, 13, in April 2012.

She has a condition called Ehlers-Danlos Syndrome (EDS) - a group of inherited connective tissue disorders - which makes her intolerant to lots of food.

She tried to exercise but just one press up or ten seconds cardio made her faint.

Tracy said: "I was crying myself to sleep. I worried constantly about what would happen to my children if I died."

"I decided to make myself as strong as I could mentally and physically."

Vegan Tracy overhauled her lifestyle - switching to a diet of curry and rice for breakfast lunch and dinner and porridge and protein shakes in between.

She became a bodybuilder, and studied mindfulness and other wellbeing techniques.

She became a Buddhist, and added yoga and meditation to her daily routine, in 2017.

She said: "Just learning to close off my mind so that I could sleep made such a difference."

"Stress is so harmful for our bodies."

Tracy had been getting Botox and fillers since her early 20s but decided to ditch the treatments after studying aesthetics and learning about the risks and side effects.

She said: "Fillers can expand years after they're put in and you can end up looking swollen."

"Basically it's all a quick fix, but your body is still ageing."

"Ultimately fillers and Botox will end up pulling your face down. You end up looking like a corpse."

Tracy became a biohacker - to make her body feel younger.

She began using a special sleeping-bag red-light therapy sauna two years ago.

She started visiting oxygen chambers every two months to combat the harmful effects of pollution on her body - costing up to £500 a session, once a month.

She said: "I come out with so much energy, nothing aches, everything is effortless."

"You can go in a tank, or just pop on a mask, and you can get all your emails done."

And Tracy now uses LED therapy to combat damage to her skin - lying on a special a £1,000 LED blanket three times a week.

She said: "It boosts your body's natural ability to regrow and replenish."

"Different frequencies get to different layers of your skin."

Recently Tracy started three sessions of EBOO blood filtration, costing £1,400 each, to detox her blood.

It involves withdrawing blood and passing it through a filtration device.

"It's incredible", she said, "I went to the gym and thought the machines were broken everything was so easy."

She drinks herbal teas, and coffee made from mushrooms, and adaptogen and other supplements instead of energy drinks.

Tracy said: "Biohacking is like putting plant food on your flowers. You take what is naturally there and boost it."

"It's like hitting rewind on the clock of life."
