Pedal off the pounds
Want to lose weight and get fit for the New Year but not
sure where to start? According to fitness company Fitness
First, we’re far more likely to do it on two wheels than on
two feet! After analysing the three million exercise sessions
that took place in Fitness First studios around the country in
2005, group cycling classes were found to be the nation’s
favourite workout – ahead of traditional classes such as
aerobics, step, circuits and even yoga and Pilates. Fitness
First’s National Health and Fitness Manager, Kevin Yates,
says, ‘I’m not really surprised by the dominance of group
cycling. It’s fun, suitable for exercisers of all fitness
levels and provides an excellent total body workout – all of
which are great motivators.’
WLR says:
Cycling is a fantastic aerobic workout that burns calories
and helps tone up legs and bums. In fact, an hour of brisk
cycling burns around 500 calories. Do this every day and you’d
lose approximately 1lb of body fat each week – that’s more
than 4lb a month, and almost 4 stone in a year! Meanwhile,
research has found that regularly getting on your bike helps
to pedal off the years as well as the pounds – cyclists tend
to have a fitness level equivalent to someone 10 year’s
younger.
But the thought of getting rained on, honked at by buses
and cycling through heavy traffic on cold, dark winter days is
all it takes for most of us to leave our bikes locked in the
shed.
That’s where group cycling classes offer a solution. The
30-45 minute classes involve ‘going for a ride’ on
stationary bikes across different types of terrain. Just like
an aerobics class, the sessions are led by an instructor and
set to music. Everyone can work at their own pace, making the
classes suitable for people of all ages and fitness levels –
and because you’re in a group, you’re far more likely to
stay motivated. Check out your local fitness centre to find

Be a boozer loser
If giving up alcohol is on your list of New Year
resolutions, you might want to think again. A new US study of
more than 8,000 people reveals that drinking small amounts of
alcohol may actually stop you getting fat! The research,
published in medical journal BMC Public Health, discovered
that those people who consumed one alcoholic drink a day were
half as likely to be obese as tee-totallers. Unsurprisingly
though, as alcohol intakes increased, so did waistlines. Binge
drinkers and people consuming four or more drinks a day were
far more likely to be overweight or obese. The authors
conclude that there’s not enough evidence to advise tee-totallers
to start drinking in an effort to shift those pounds. However,
they also say, ‘The evidence reported here argues against a
strategy of promoting complete abstention, at least among
those who regularly consumer alcohol.’ In other words, there’s
no need to give up the odd tipple when you’re trying to lose
weight!
WLR says:
This survey is certainly interesting but it doesn’t
change the fact that most alcoholic drinks are packed with
calories and no other nutrients. A single measure of spirits
alone provides 50 calories, while a 175ml glass of wine
provides 115 calories and a pint of ordinary strength lager
165 calories. Meanwhile, a pint of strong lager contains
around 250 calories. As this research suggests, you don’t
have to ‘give up’ booze completely – but you do need to
count the calories. After all, it’s not called a ‘beer
belly’ for nothing!
Shake off those ‘fat’ days
Ever had a ‘fat’ day and found that rather than making
you more determined to stick to your diet and exercise plan,
its leaves you with a devil-may-care attitude that sees you
seeking solace in the fridge? Fortunately, scientists may have
found the answer by creating a gadget that tricks the mind
into believing you’re thinner than you actually are.
Researchers from University College London attached a
vibrating device to the wrists of 17 volunteers, which
simulated the sensation that the joint was flexing even though
it remained still. Next the participants put their hands
around their waists while the researchers scanned their brains
to identify the part of the brain involved in body image. The
study discovered the highest level of activity was in the
posterior parietal cortex – the part of the brain that
assimilates sensory information from different parts of the
body. But best of all, the volunteer’s thought their waists
had shrunk by up to 28%!
WLR says:
This research has been carried out predominantly to improve
our understanding of the part of the brain that’s involved
in causing body image problems in people with eating
disorders. Nevertheless, it’s interesting that such a simple
device helped people to feel significantly thinner. This
alone, may have important implications for helping people to
lose weight. Regardless of what the scales say, simply feeling
thinner is often all it takes to give us the motivation we
need to stick to our diet and exercise plan.
Unfortunately, there are currently few vibrating devices
available for attaching to your wrists, so for now, you’ll
need to deal with ‘fat’ days using more traditional
methods. Before heading for the fridge, reflect on your
successes so far. Think about how much weight you’ve lost,
how many inches you’ve dropped and how much more toned you
feel. Look at old photographs of yourself before you started
out and try on old clothes that are now too big for you. This
should be enough to help you turn that ‘fat’ day into a
‘thin’ one – and leave you reaching for the fruit bowl
rather than the biscuit tin!
A bum note
Here’s yet another good reason to lose weight. Doctors
have discovered that longer needles may be needed for
administering injections to bigger bottoms. Researchers from
Dublin studied 50 people and found that overweight women were
less likely to receive the full dosage of drugs because of
their fleshy bottoms – quite simply, the needles weren’t
long enough to reach the muscle with the result that the drugs
were less effective. Dr Chan, who led the research, said many
of her patients were receiving little, if any, benefit from
injections administered to the buttocks, because of obesity.
‘The amount of fat tissue overlying the muscle exceeds the
length of the needles commonly used for these injections,’
she concludes.
WLR says:
This is an interesting study and clearly more research is
needed. The bottom tends to be the main site for many
injections such as painkillers, vaccines, contraceptives and
anti-sickness drugs. This is because there are few major blood
vessels, bones and nerves that can be damaged by a needle and
the muscle underneath the layer of the fat on the bottom has a
rich supply of tiny blood vessels that can effectively absorb
the medicine. Our advice is to use this information to spur
you on to shift those pounds once and for all. And in the
meantime, if you need to have an injection in your bottom and
are still a long way from reaching your target weight, ask
your doctor for advice.
Dieting by intuition
According to a new study published in the American Journal
of Health Education, surrounding ourselves with our favourite
foods may actually help us to lose weight – providing we
only eat them when we’re hungry and stop when we’re full!
Dr Hawks, who led the research, wanted to see whether people
lost weight when they were allowed to eat whatever they wanted
when they were hungry – a concept he calls ‘intuitive
eating’. He’d already lost 50lb and kept it off for five
years by surrounding himself with all the ‘unhealthy’
foods he craved. Amazingly, his research showed that intuitive
eating was linked with a lower body mass index and higher
levels of HDL or ‘good’ cholesterol among female students.
Dr Hawks suggests these findings provide support for the idea
that intuitive eating can help people to lose weight.
WLR says:
The results of this small study need to be interpreted with
care and more research needs to be done before we start
recommending people surround themselves with crisps, cakes and
chocolate – and eat them whenever they feel hungry. We agree
it’s important to learn to recognise feelings of hunger and
fullness and to avoid eating emotionally, for example, when we’re
bored, tired or miserable. And we don’t believe in denying
ourselves our favourite foods when we’re trying to lose
weight. But the concept of ‘intuitive eating’ does little
to teach us about the importance of a balanced, healthy diet
that’s sustainable for life. Typically, many of our
favourite foods are high in fat, sugar, salt and little else,
with the result we could be left short on essential vitamins
and minerals. Meanwhile, these types of foods typically
provide us with a short-lived burst of energy, quickly leaving
us feeling hungry again so that we need something else to eat.
Our advice is to stick to a daily diet that’s packed with
fibre-rich carbs, five fruit and veg, lean protein-rich foods,
low-fat dairy products – and a daily treat, whether that’s
a packet of crisps, glass of wine or bar of chocolate.
Don’t ditch the dairy
In the past, many people avoided milk and dairy products to
help shift those pounds. But over the years, more and more
research has shown that low-fat dairy products – and
specifically the calcium they contain – actually work with
our waistlines rather than against them. Now, a Portuguese
study of more than 37,000 adults has added more weight to the
science by revealing that men and pre-menopausal who drink the
most milk are less likely to be obese than those who drink the
least. The same relationship wasn’t found in post-menopausal
women, which the researchers say may be due to hormonal
differences, and needs more investigation.
Meanwhile, a study published in the American Journal of
Clinical Nutrition has shown that drinking skimmed milk can
half the risk of high blood pressure. Spanish researchers
followed the diets of 6,000 people for two years and
discovered that those who drank skimmed milk and ate other
low-fat dairy products were 50% less likely to suffer from
high blood pressure than those who consumed little or no
skimmed milk or dairy products.
WLR says:
The calcium in dairy products is essential for healthy
bones, but increasingly, research shows it may also have other
important health implications, particularly in terms of
helping people to lose weight and lower blood pressure. We
recommend including at least half a pint of skimmed milk in
your daily diet. This contains just 100 calories but 340mg
calcium – around half the amount of calcium needed by most
adults for good health. Use it in tea and coffee, drink it on
its own, use it on cereal or blend it with fruit to make a
smoothie. And if you don’t like milk, have two small pots of
fat-free fruit yoghurt instead to ensure you get the calcium
– and weight loss benefits – of dairy products.
Turn it off
Research from New Zealand has confirmed that watching large
amounts of TV makes children fat. Worse still, the study
reveals that TV viewing has a greater impact on body mass
index than even diet or inactivity. The research, published in
the International Journal of Obesity, followed the viewing
habits and weight of children at regular intervals between the
ages of three and 15 years. ‘Our research showed that time
spent watching TV is a significant predictor of body mass
index and being overweight,’ says researcher DR Hancox. ‘Significantly
reducing the amount of television children watch would be an
important first step in an attempt to tackle the current
epidemic of childhood obesity,’ he concludes.
WLR says:
If you’re concerned about your child’s weight you might
want to follow in the footsteps of the popular BBC show Honey,
We’re Killing The Kids and start removing TV sets from your
home, particularly your child’s bedroom. Encouraging the
whole family to get off the couch and be more active will make
big differences to everyone’s health and waistlines. And
remember that children will follow your example, so if they
see you skipping Corrie to go for a swim, they’ll be more
likely to do the same.
