Presenter George Lamb and a group of doctors advise people with excessive lifestyles how to become healthier and avoid serious illness.

23-year-old Bobbi lives in Plymouth with her partner Adam and her 14-month-old daughter Gabrielle. Bobbi smokes and drinks too much, but even worse is her diet - for nearly 20 years Bobbi has eaten no fruit or veg whatsoever. Her terrible diet consists solely of pizzas, kebabs, burgers, chips, bacon and sausages.

Her toddler daughter Gabrielle is picking up on her mum's vegetable aversion and is already a fussy eater, preferring baby fast-food to anything made by Bobbi. Bobbi is desperately worried that, like her, Gabrielle will grow up refusing all fresh produce unless she herself changes her poor diet and eating habits.

For Bobbi, all this has led to constant exhaustion, weakness and bad mood swings. Tired all the time and lacking enough energy to run around with her daughter, Bobbi does no exercise and even drives to the shops she can see from her sitting room window. Takeaways and junk food put a strain on the family's budget and Bobbi and Adam end up arguing about money.

Can no-nonsense nutritionist Alice Sykes expand Bobbi's horizons and in particular her diet? If she can, it might literally add years to Bobbi's life expectancy. Show less
