Five diets that get the experts' thumbs down
If Weight Watchers is top of the class, then this recently released study by leading health group, the British Dietetic Association, reveals the diets at the other end of the scale. In fifth place it's the . . .
5. Baby Food Diet
WHAT IS IT? Like its name suggests, the diet revolves around eating some 14 jars of baby food or puréed food a day. A less intensive version is to eat mostly baby food and then have one adult meal or to eat baby food instead of your daily snacks.
WHAT THE EXPERTS SAY: This is portion control taken to an extreme. It also reduces calories, fibre and, because you're not chewing, you'll not feel full. Leave baby food to babies.
CELEB FANS: Lady Gaga and Jennifer Aniston are rumoured to have given it a try.
4. Raw Food Diet
WHAT IS IT? Only eating raw food or food heated below 47C so as not to kill its enzymes -- not getting enough enzymes is associated with weight gain. Avoid all preservatives, additives and food grown with pesticides. Oh and anything cooked.
WHAT THE EXPERTS SAY: Whilst it can be low in fat and calories, the diet can also be low in calcium, vitamin D, iron, zinc and protein. It also excludes a lot of foods -- potatoes, pasta and bread to name but a few-- that need cooking.
CELEB FANS: Demi Moore and Natalie Portman are reported to be fans.
3 Blood Group Diet
WHAT IS IT? It claims nutrients are broken down differently according to blood type. So to stay slim, Blood group A folk, for example, shouldn't eat dairy or meat.
WHAT THE EXPERTS SAY: This is pseudo-science and again, cutting out any food groups is unhealthy.
CELEB FANS: Cheryl Cole and Courteney Cox Arquette are reportedly fans.
2. Drunkorexic Diet
WHAT IS IT? Shunning food during the week to bank your week's calorie allocation and blow it on a boozy drinks binge.
WHAT THE EXPERTS SAY: Madness. You're starving your body of vital vitamins and nutrients and could end up with alcohol poisoning.
CELEB FANS: No-one who will admit it.
1 DUKAN Diet
WHAT IS IT? French-devised no-carbs diet -- cutting out bread, pasta etc.
What the experts say: The BDA rates it the top one to avoid.
Celeb fan: Kate Middleton's mum.
