However, new research shows that while yo-yo dieting is bad for you, it is unlikely to lead to an early death.

Participants were asked about how often they had intentionally lost ten or more pounds and later regained the weight, with a total of 42 per cent of men and almost 57 per cent of women admitting they had done so at one or more times in their life.

Among women whose weight yo-yoed 20 times or more during their life, 16 per cent died during the study's 16-year follow up period, according to findings published in the American Journal of Epidemiology.

This compared to 15 per cent of those who said their weight never fluctuated in this way due to dieting.

However, participants who yo-yo dieted the most were more likely to be heavy ten years before the beginning of the study, which could elevate their risk of mortality.

Helen O'Donnell, presenter for Weight To Go diet food company, said that it is "vital" to start the day with a good breakfast, with evidence showing that people who eat a morning meal are slimmer than those who do not.

She added that some experts believe that eating breakfast are more likely to make healthier dietary choices throughout the rest of the day.

"Eating high fibre and slow release foods such as porridge or muesli helps to keep you feeling full until lunch and stops you from snacking on sugary treats," she explained.

Furthermore, it is always a good idea to have a piece of fruit on hand that is not too messy to eat, and you can snack on during the day, added Ms O'Donnell.

A study by YouGov for Weight Watchers revealed that February is the month where people feel unhappiest with their weight and lifestyle, thanks to failing at weight loss new year's resolutions.

It was revealed that almost half of Brits have at one time made a new year's resolution to lose weight, but by February 1st some 24 per cent have already broken one or more of their vows for 2012.

One in ten of those surveyed were depressed about not being able to stick to their weight loss resolution, while 11 per cent feel bad about not fitting into their clothes after Christmas overindulgences.

Furthermore, 34 per cent said that breaking their resolutions led to unhappiness within themselves, with 24 per cent feeling angry and one in five experiencing feelings of failure.

However, according to one expert, many people think using superfoods is a lot more complicated than it actually is.

Dr Claire Kelly, owner of Indigo Herbs, noted that is it "really super accessible", noting that just a couple of teaspoons of Barley Grass in a drink each day is more than enough.

She said that a "superfood revolution" is occurring, with people sharing their stories on websites, blogs and forums and speaking of the "amazing health benefits" they can offer.

She added the superfoods are much more affordable now than they were ten years ago, and that this is a "people-driven movement".

"It is not about a big marketing revolution by big multi-national companies, it is real people getting on with it, sharing their stories and sharing what is working for them in their lives," she said.

Male liposuction has also increased in popularity, with an eight per cent rise, alongside nose jobs, eyelid surgery, ear correction and face and brow lifts.

Joanna Knight, editor of Women's Fitness, said that purchasing a few pieces of key equipment make a "sound investment".

She noted that as people continue to feel the effects of the recession, they are looking for ways to work out for less.

"The number of people enjoying free activities like running and cycling has increased in the last few years and home workouts also offer an affordable way of getting fit too," the expert commented.

The major benefits of working out at home, Ms Knight said, is that you cannot make excuses for not going, you can wear what you like and you don't have to queue for the showers.

People considering a home gym should opt for lightweight equipment that is easy to store away, she explained, unless they are dedicating an entire room of their house to the gym.

Leading nutritionist Dr Marilyn Glenville said that food no longer contains the nutrients it once did, so that even with the best of intentions, well balanced diets can be a "myth".

Overfarming and the use of pesticides means that the soil food is grown in has become depleted in vital nutrients, and many fruit and vegetables are sat in a warehouse for a while before hitting the shelves.

Furthermore, ready prepared vegetables, such as sliced carrots, also contain fewer nutrients, she explained.

"Supplements are just that, supplementary to your diet and not a substitute for a healthy one. Your goal should always be to eat well. Supplements are like a sort of health insurance, not a replacement for eating properly," Dr Glenville concluded.

Alex Bodikian, brand representative for FULLfast, said that people should find something that will boost their diet because new year weight loss can be "a little bit harder than first anticipated".

According to the expert, January 14th is the day people are most likely to throw in the towel when it comes to new year's resolutions, especially when they are weight loss related.

"It tends to happen because by the middle of January, their happiness levels have really hit rock bottom," she explained.

Dieting in the new year tends to take on a new importance because so many people choose to do it to try and make up for Christmas excesses, she explained.

This follows advice from nutritional therapist Charlotte Watts who said dieters should avoid going "from A to Z too quickly", but instead ease themselves into new year's weight loss resolutions.

Lynsey Haywood wrote in the Sun that if skin is flaky or dry, it could indicate the individual is not getting enough essential fatty acids, which are gained through the consumption of certain fish, seeds and nuts.

Sagging skin can be due to chemicals in fried food as well as cigarette smoke and the sun, while pimples indicate stress, the expert added.

She named a few foodstuffs that can be extremely useful when it comes to eating your way to a better body, and improved skin.

Blackberries were first on the list, as they help the body to produce collagen and are rich in antioxidants, which combat signs of ageing.

Also making the top five were oily fish, such as sardines, mackerel and fresh tuna, kiwi fruit, dark chocolate and asparagus.
