Put simply, clean eating is choosing foods in their whole, natural state, avoiding processing and additives. There's no doubt that highly processed foods have played a major role in our obesity problem, and these diets are right to promote eating more fruit and vegetables. But there is a dark side to eating clean: dietitians say the nutritional advice is too often based on bad science - and 'clean' diets are expensive and unsustainable.

EXCLUSIVE: Dr Christian Jessen (left), best known for his medical advice in Channel 4's Embarrassing Bodies, grew up watching his uncle Volker's (inset and right) battle with the cruel condition. Here, speaking to the Mail, he shares his uncle's tragic journey from a healthy and active vet to being wheelchair-bound and cared for by his devoted wife. It comes as a new website called 1message is launched, which aims to give MS patients choices about their care. Dr Jessen said: 'Thankfully MS is no longer a death sentence - especially if those with it reach out for specialist help.'

From the outside, Jason Watkins and Clara Francis look like a couple who have it all. He's one of Britain's most acclaimed actors who starred in the BBC spoof show W1A and was awarded a Bafta for his role in the ITV drama The Lost Honour Of Christopher Jefferies. But what outsiders don't see is the black hole at the heart of their family, left by the loss of their youngest daughter, Maude. Maude died, aged two-and-a-half, on New Year's Day, 2011.

The stark warnings from health experts that 'sugar is the new smoking' prompted millions of Britons to turn to diet plans that promised guidance in how to drastically cut their intake. Now an investigation by The Mail on Sunday has revealed some of the top-selling 'sugar-free' recipe books are far from what they claim to be on the cover. While omitting traditional table sugar, they contain numerous dishes laced with sugars from syrups and other sources.

Charlotte Amos, 17, from Torbay, Devon, first began losing weight aged 11 after school bullies mocked her when she ate, calling her a 'pig'. And as the pounds fell off, her confidence soared. 'Whenever someone would notice I'd lost weight they'd compliment me on it and that would make me want to lose even more,' she said. But over the years her condition deteriorated until she was too weak to get out of bed (left and top centre) - and was forbidden from going to her beloved dance class. 'I've always wanted to be a dancer - so I was devastated when my parents and the dance school said I was too weak and needed to recover before going back. For me to realise I may never dance again was heartbreaking. I had no energy but it was all I wanted to do, that's when I knew I had time to change.' After receiving treatment in hospital, she is now on the road to recovery, and even won the Miss Teen Devon Galaxy beauty pageant, which she said has boosted her confidence (right).

While Instagram has typically been a feminine domain (53 per cent of its total users are women), we're now more likely to turn to a growing number of men for our daily fix of fitspiration. Ben Mudge (left and inset), 25, from Belfast, posts regular photos post 'leg session', while Ali Gordon (right), 26, from Buckinghamshire, has a combined social media following of 200,000, thanks to his smouldering selfies and posts on healthy living. He regularly posts before and after shots of his female clients, as well as the healthy meals he cooks for wife Janice, who he is currently training up for a 250k challenge.

Samantha Stroud, 29, of Exmouth, Devon, is furious that daughter Honey-Rose, has been branded as overweight based on her BMI score. Honey Rose (left) was asked to join a weight management scheme to help her shed the pounds and maintain a 'healthy' weight. But Mrs Stroud (right, with her daughter), said labelling children at such a young age amounts to 'body shaming' and can trigger anorexia. She says Honey-Rose is perfectly healthy, walking everywhere and eating her fruit and vegetables. She said: 'A child at the age of four should not be worried about going on a diet. Someone in my family has severe anorexia so to have someone almost body shame my four year old is appalling.'

He's been open in the past about his skin cancer procedures and on Monday Hugh Jackman revealed he's had yet another growth removed from his nose. The Australian actor, 47, shared a selfie on Instagram (left) showing a large Band Aid stuck right across the bridge of his nose. 'An example of what happens when you don't wear sunscreen. Basal Cell. The mildest form of cancer but serious, nonetheless,' he wrote alongside the photo. 'PLEASE USE SUNSCREEN and get regular check-ups.' He is also pictured top right back in 2014 and bottom right 2013 with Band Aids on his nose.

Elizabeth Spencer (pictured, right), 5, first suffered with flu-like symptoms like a headache, but the next day she collapsed and was rushed to A&E; where she was put in an induced coma (left). Just 18 days later she passed away. The cold-like virus triggered an extremely rare auto immune condition which sent her body into overdrive to fight off the original virus. her heartbroken mother, Natalia, from Cheltenham, said: 'I couldn't believe it. In the morning I thought she had a flu and in the evening I was told she probably wouldn't make it.'

Kathryn Flett, pictured, loves the sound of the Babyface Drip, an intravenous vitamin and mineral infusion. She tries out the drip, which contains wrinkle-erasing ingredients, including vitamin C, vitamin B complex and glutathione. She's impressed with the results, and has more energy afterwards.

Ross Edgley, 30, from Cheshire, braved the pouring rain to complete the epic challenge non-stop in 19 hours, 36 minutes and 43 seconds. Held at Silverstone's iconic racetrack, it left him not only exhausted, but with an
'unholy amount of harness chaffing'. His aim? To raise as much money as possible for four charities close to his heart after several family members and friends were diagnosed with devastating conditions. But preparation for the mammoth task - a very real case of blood, sweat and tears - began eight months before. The demands of getting so physically fit meant a gruelling fitness regime was crucial. At times, Ross - a former international athlete, swimmer and water polo player for Great Britain - was required to train for up to 14 hours a day. He also shovelled down a staggering 6,000 calories a day on a high fat diet, eating coconut and almond oil by the jar. If, he says, he raises enough money and awareness for charity, he will consider 'every blister, rope burn and early-morning-ice-cold run not in vain'.

Ashton Howard, 28, from the Isle of Wight, had been enjoying holidays to Croatia and Ibiza when she started feeling unwell. She started feeling dizzy after one gin and tonic on New Year's Eve in 2013 (left). She discovered her symptoms were being caused by acute lymphoblastic leukaemia the following January and started intensive treatment where friends and family could only visit if they were wearing gowns (right). The chemotherapy caused her hair to fall out (inset) but she was pleased when it grew back straight. Following her treatment, she gave up her busy life in London in favour of a quieter life. 'I now have a better lifestyle. I do yoga and paddleboard. I love being by the sea,' she said.'I'm not glad I got cancer, but in some respects it has improved my life.'

GRAPHIC CONTENT Louise Greene, 19, from Essex, and her fiance Tommy Acott have revealed how Scarlett was born with a bruised scalp and a 6cm cut on her head after a complicated birth. The newborn, who is now a year old, arrived in Basildon Hospital weighing 7lbs 6oz, and was rushed into intensive care in an incubator looking like a 'bloody mess'. However a spokesperson for the hospital told how staff were forced to act as 'quickly as possible' after the baby's heart rate dropped, indicating she was in distress.

Jasmiena Gyer, 40, from Cape Town, South Africa, has a rare skin condition causing pale patches to develop all over her body due to a lack of pigment polymer melanin. After two decades of cruel comments Jasmiena felt unable to go out during the day time and suffered from low self-esteem. However the support of fellow sufferers has encouraged her to 'stop hiding' and helped her to realise that she is beautiful. In a show of strength, the mother (pictured with her children Adam and Imaan, left) posted her first selfie to Facebook last week (left).

Claire Gaylor, 37, from Hertfordshire, had a normal pregnancy (left and scan, top middle) until 28 weeks when she started to get horrendous pains which felt like her 'womb was popping'. Doctors initially thought it was severe heartburn and prescribed oral morphine. When her symptoms got worse, she was taken to the delivery suite where doctors found she had the disorder placenta percreta. This caused the placenta to rupture her womb, filling it with blood. Cody had to be resuscitated twice after he was born (bottom middle) after swallowing her blood but has since gone on to make a full recovery with Mrs Gaylor (right). Mrs Gaylor woke from a coma to find out she had already given birth to Cody. She said: 'I couldn't believe how much he had been through, he was such a little fighter and really is our little miracle.'

Vice correspondent Isobel Yeung (bottom left) speaks with potential parents who have opted to choose the sex of their child (right) on Friday night's episode of the HBO documentary series. The journalist also visits the National Research Center for Mutant Mice in Nanjing, China (top left), where CRISPR technology is being used to edit the genes of mice.

Georgia McGrath, 18, from Hull, lost half of her body weight after being called fat at school. She skipped meals and exercised obsessively, causing her weight to plummet to five stone (left). The turning point for her recovery came when she fractured her ribs while hugging her boyfriend Ashton (centre, inset), which was caught on camera (centre) by a friend. Her family's reaction and her great-grandmother's dying wish for her to beat anorexia helped her to overcome the disease. She now weighs a healthy 10st 4lbs (right) and has set up her own business. Miss McGrath said: 'The photograph incident was a real wake-up call for me. I knew I couldn't go on like this any more and started fighting against my eating disorder.'

Emma Robinson (pictured left before and right after), 34, from Bournemouth, feels like she has 'taken a step backwards' after her seven stone weight loss left her with mounds of excess skin on her arms and breasts (inset). She lost the weight for her September 2015 wedding to husband Matthew, but now says it has destroyed her confidence, with her E/F cups even causing her back pain. After being refused corrective surgery on the NHS, she is now crowdfunding for the £4,500 needed to have the excess skin removed.

Ellie Penrose, 18, was 'inappropriately discharged' from Hull Royal Infirmary (inset) after a 'failure in care', a hospital chief has since admitted. The teenager - who represented Great Britain in triathlon and learned on the day she died that she had excelled in her A-levels  - was suffering from sickness, a headache and an aversion to light when she was initially taken to hospital in August last year. She also had blotches on her skin. The inquest into her death has heard there was no consultant available in A&E; so she was seen by a junior doctor, who sent her home with ibuprofen.

Emily Corrigan, 28, from Watford, considered herself perfectly fit and healthy until she passed out last July. To her horror, the 28-year-old was diagnosed with a grade two brain tumour and needed surgery to remove part of her skull to get rid of the tumour. She said: Whenever I got a headache or felt tired I just put it down to looking after my kids. I was stressed and never thought anything more of it.' And after realising there was a lack of awareness and fundraising for brain tumours, she decided to post a picture of her scar to Facebook last week - which has generated a tremendous response. She said: 'When I went to London for my surgery, there was one lady on my ward (dedicated brain tumour ward) who celebrated her 80th birthday there, everyone else was under 40, and all of us had young children.' Pictured are Sonny, 8, Harvey, 5, and twins Francesca and Annabel, 3.

Mohini Singh, 20, from India was stunned when she gave birth to the twins who have two hearts, two lungs and healthy limbs but share a liver. The parents were unable to afford checks up and ultrasound scans during pregnancy and now cannot afford an operation to separate them. The dad only earns £50 a month but desperately wants to save his daughters and hopes the government might help.

Katherine Simpson-Jacobs, 43, from Suffolk, said breaking the news to her children, Anna and Sofie, then just six and four years old, was a 'huge added pressure' at an already stressful time. The secondary school teacher penned the story, 'What We Did When Mummy Got Cancer' while she was under-going treatment. Pictured from left, Katherine with her girls and partner Richard, 42. Inset, the book.

Victoria's Secret models have some of the most longed-after physiques of anyone. Exercise and diet are key to making the cut. Miranda Kerr (left) attributes her incredible figure to chlorella supplements, as well as eating plenty of greens. Andriana Lima (centre) makes no secret of Omega-3s being her go-to supplement, which are needed to absorb important nutrients such as the fat soluble vitamins, A, D E and K. Model Rosie Huntington-Whiteley puts her wash-board toned stomach down to vegetable juice. Here, an expert gives her view on some of their top tips to stay in shape.
