Dr Sally Norton gives her verdict on the pros and cons of the Mediterranean diet, cutting out fat, and sugar, as well as the Low GI diet, concluding the answer is not as simple as picking just one. She said: With so many different diets offering quick results and dramatic weight loss, it can be difficult to see the wood for the trees. The main thing to realise is research has shown time and again that 'quick fix' diets barely last a couple of weeks, and seldom keep the weight off long-term. Over the years I've spoken to numerous women have undertaken on one of the many available diets, and on almost every occasion, their plans have failed. Not because they don't want it enough, but just because crash diets don't work and lead to that inevitable rollercoaster of weight-loss and weight-gain that we hear so much about. So, what are the pros and cons of four popular approaches to weight loss, and what should you do?'

Fitness guru and model, Chontel Duncan (pictured), from Brisbane, Queensland, has shared a snap of her incredible post-baby body just five days after giving birth (right). Mrs Duncan did admit that she felt as though someone had used her core as a boxing target and said 'so much healing is yet to happen.'

Melissa Mead, 29, from Penryn, Cornwall, announced her news on today's Good Morning Britain as she held a teddy bear containing the ashes of her son, William, wearing a T-shirt which read 'I am being promoted to Big Brother' (inset). Melissa (left today) told presenters Kate Garraway and Ben Shephard: 'We are expecting our second child. We can't wait to tell the new baby all about his wonderful big brother - his or hers.' The pair offered their congratulations to Melissa and her husband Paul who lost their 12-month-old (pictured right with Melissa) on December 2014. An inquest heard last June how he died after an NHS 111 operator, with no medical training, advised his mother to give him plenty of fluids, Calpol and Ibuprofen when she called for advice about his symptoms. The 12-month-old had developed an abscess in his left lung caused by the bacterial infection streptococcus A. But had the out-of-hours service advised Melissa to take William immediately to hospital he could still be alive today, the hearing was told.

Kirsty Keep, 23, of Maidstone, Kent, was diagnosed with lupus after suffering seizures and chronic pain. For the last seven years she has been receiving treatment for autoimmune condition lupus - including steroids and chemotherapy (left, in hospital, centre and right, on a good day). Last month, the agony became so unbearable miss Keep begged her mother Theresa to take her the Swiss suicide clinic Dignitas. But a specialist at Guy's Hospital this month said her symptoms, including chronic pain and seizures, could be due to a genetic skin and bone disorder such as Ehlers-Danlos syndrome. Her mother Theresa is angry her daughter has received unnecessary and potentially harmful treatment. She said: 'I can't believe it. Kirsty has been receiving chemotherapy, steroids and all sorts of damaging stuff, which she might not have needed. I'm so angry.'

Lalao, 50, didn't think anything of the small bump that appeared on her face more than a decade ago. But eventually, the tumor grew into an 11-pound mass - the size of a bowling ball. The mother-of-four from Madagascar sought out help from two local hospitals - both of which accepted her money and gave her false hope, but were ultimately unable to operate on her. The school teacher and her husband Alfred (pictured with Lalao right) heard about the charity hospital Mercy Ships, which sails around Africa offering free medical care. After lining up for eight hours, having sold a pig to pay for transport to the port, she was told Mercy Ships would be able to help her - and in November 2015, she was admitted for surgery after the boat docked in Toamasina. Two days later, the team of experts removed the benign tumor in just one operation. Lalao said, 'The next morning, I just woke and it was gone. Finally, l was free of that big mass.'

She wrote: 'How lovely to see the phrase I said to my teenage/ young adult self that also led to me calling myself a ''fat , disgusting waste of oxygen'' often before self harming just because I had dinner.' The post (top right) has now has more than 5000 likes, has been shared 2000 times and caused outrage among those commenting (bottom right). Kate Doran wrote: 'Wow I can't believe they would put such a known pro-ana phrase on a set of scales! It's like the most irresponsible thing ever.' Eating disorder charity Beat slammed the product as 'irresponsible' and accused B&M; of 'thoughtless retailing'.

Ximena and Scarlett Hernandez-Torres (pictured left and right with their sister Catalina and mother Silvia Hernandez, 23) were born in May last year as part of a set of triplets in Corpus Christi, Texas. The likelihood of having conjoined twins as part of a set of triplets is around one in 50 millions, experts say. Not only that, but the way the little girls are connected to each other is a rarity too. They are joined at the pelvis, have separate legs and share a colon, as well as some organs such as the uterus and ovaries. Only six per cent of conjoined twins are connected this way. Now, doctors at Driscoll Children's Hospital are getting ready to separate them during a procedure that will last 12 to 18 hours.

Shaelyn Boostrom, 16, began suffering from headaches at age six, but didn't think anything of them until they transformed into painful migraines. By age 15, the migraines were painful and would cause her to vomit - in addition to leaving the left side of her body weak. A MRI found a tumor (inset) the size of a golf ball in her brain. Shaelyn was told that she could wait - or undergo a surgery to remove the tumor right away, even though it could leave her brain dead. The teenager bravely opted to have the procedure - and survived, with 16 staples and 20 stitches in the shape of a question mark. However, the teenager developed epilepsy after the operation - but medication is helping to manage the newfound condition. Shaelyn says the procedure gave her a second shot at life and that she feels 'like a whole new person.'

He is now home with his brother (right) and are enjoying each other's company again. Mother Zoe Pickering said: 'It is really nice to have him home. Hunter is so excited and keeps cuddling him and kissing him. He just wants to play with him all the time.'

Once it was cancer, but now surveys show that dementia is our most feared disease. It refers to a set of symptoms, including loss of memory, confusion and difficulties with thinking, or language, caused by some sort of damage to the brain. Typically it starts after the age of 65 and the risk increases with age, with one in six 80-year-olds affected. The best that drugs currently available for it can do is slow the progression of the disease or temporarily alleviate the symptoms. Dr Naji Tabet assesses five people from age 28 to 68 for their risk.

The campaign, by the Diabetes Association of Thailand, aims to raise awareness to the little-known complications of type 2 diabetes, including poor wound healing, ulcers and gangrene. This occurs because high blood sugar levels damage the body's blood vessels and lower the immune system, meaning cuts don't heal as fast and raising the risk of infection. In the worst cases, infected wounds mean limbs have to be amputated. Pictured (left, right and inset), confectionery has been arranged to look like deep, infected holes in the body's arms, legs and feet.

Holly Brockwell, 30, from London (left, and right with boyfriend Zack), has appeared on This Morning to share her happiness as doctors finally agreed to sterilise her following a four-year battle to prove that she never wants children. The technology journalist had asked for the procedure every day since she was 26 but doctors refused because of her age, offering to give her boyfriend a vasectomy instead. After numerous attempts to get a referral from her GP, Holly learnt last week that she had finally been put on the list for the operation, which will take place in the next few months.

Celina Leroy, 24, from New York, always tried to hide the large red mark - but now she's embracing her difference and modelling without make-up. She spent $10,000 on 40 laser treatments and two operations to hide it since the age of one (inset), but now Celina is proud if the port wine stain. But now the model has decided to embrace her unique birthmark and has started posing for photoshoots without covering it with makeup. She's found that people have been supportive of her decision.

She is now relying on the support of her family - daughter Savi, son Nathan Fields, and her fiance, Rocky Gerner (inset), who she will marry this summer. Despite the fear she felt when she was told she had cancer, she says she will now stand up for all women. 'Have regular breast examinations please. Girls past 30 it's very important,' she says.
