A "cure" for obesity?

Obesity is one of the biggest problems in society today.  It affects more than 500 MILLION people worldwide and is threatening to bankrupt most public health services.  Obesity isn't just a FAT problem, it also increments the risk of type 2 diabetes, heart disease and cancer.

Most people see an obese person and think that they over eat and don't exercise enough and, in some cases they would be right.  However, not all obese people suffer from being lazy and lie around eating everything and anything they can get their hands on.  Throughout the decades when scientists have compared the diet of an obese person to that of a lean person, there weren't many differences - in what or how much they were eating.  In fact the one BIG unresolved question is why do some people get fatter than others when eating and moving the same?

Yes there are cases of hyperthyroidism where people with an overactive thyroid tend to be thinner and burn all they eat, or the contrary where hypothyroidism means a slow working thyroid gland that means a person gains weight.  Both conditions are a problem and have other health problems associated.

But there are people who are healthy but have a tendency to put on weight with frightening ease.

Back in 2007 the FTO gene was discovered.
Fat mass and obesity-associated protein also known as alpha-ketoglutarate-dependent dioxygenase FTO is an enzyme that in humans is encoded by the FTO gene located on chromosome 16 - certain variants of the FTO gene appear to be correlated with obesity in humans. (Wikipedia)
The discovery of this gene challenges the notion that people get obese out of choice because they

choose to eat too much and not exercise.  However, it's not all as clear as it seems, the FTO gene was discovered in 44% of Europeans but only 5% of blacks, meaning that other genes are clearly at work and food and exercise ALSO play an important part in maintaining a healthy weight.

Fortunately scientists have identified a "switch" to turn off the FTO gene.  Harvard and MIT researchers managed to block the gene's effect in mice and found that the mice became 50% leaner than other mice even though they were eating a high-fat diet.  Those mice also burned more energy while sleeping.  The same experiment on human cells found that energy burning in fat cells was increased resulting in less fat being stored.

However, Manolis Kellis a professor at MIT stressed that the FTO gene does not automatically make a person obese, it just made it more likely.  The researchers went on to say that they did not know how long it would take to develop an effective treatment for obesity and also said that they doubted there would ever be a pill that would let people eat whatever they wanted and not gain weight.

Also, any drug would need rigorous testing as it would likely have a knock-on effect on other areas of the body.  However, this is big news with a lot of potential for helping the obesity epidemic.

Lose weight the delicious way...

That ominous word... DIET... instantly conjures up mental images of grilled chicken breast with lettuce and... not much else.

If you read this blog regularly you'll know by now that I am not a chicken and lettuce believer, in fact here are 18 FAT BURNING FOODS that are deliciously full of healthful nutrients that will not only help you lose weight, but you'll love every moment of your "diet".

In my opinion foods with a label aren't foods at all.  On the whole we eat way to many foods that are so refined their nutritional content is severely lacking.  Nutrient dense foods will supply you  with everything you need and keep you feeling fuller for longer, helping to beat those pesky cravings and making your diet much more successful.

So, polish off your knife and fork and unlock the kitchen, it's time to EAT!

1.  Coconut.  Love coconut!  Packed full of healthy fats in the form of medium chain fatty acids (MCFAs) which are broken down by the body and used for energy production, effectively kickstarting your metabolism.  You can use coconut oil for cooking, it supports higher temperatures and you need a lot less than other oils.   Raw coconut as a snack between meals is also great especially if you are on the go.

2.  Green Leafy Vegetables.  Packed with vitamin A and C as well as calcium, green leafy vegetables are a great way of reducing oxidative stress in the body.  Eating green leafy vegetables reduces stress hormones in the body so they don't get stored as belly fat.

3.  Avocado.  My all time favorite.  You must get avocado in your life.  Bursting with healthy fats and fiber, avocados boost your metabolism and accelerates the conversion of fat into energy.  They also fill you up for a long time.  I quite often recommend avocados for breakfast for hungry people who say that fruit just doesn't do it for them in the mornings.  Avocado really hits the spot providing energy and filling you up.

4.  Fish.  Especially oily fish such as wild salmon, mackerel, tuna, etc...  Packed with Omega-3 which is really good for your brain, fish also have a positive effect on Leptin.  This hormone regulates fat storage, so eating fish which has a positive effect on Leptin will keep you in control of your weight.

5.  Lean organic meats.  Animal protein is an important component of a healthy diet, it helps repair damaged areas of the body and provides essential amino acids.  It also has a thermogenic effect which means it makes your body burn more calories to digest it (remember my post about Negative Calorie Foods?)

6.  Green Tea.  Not so filling I'm afraid but green tea contains catechins.  These are a type of phytochemical that has an effect on metabolism which then promotes fat oxidation and thermogenesis, as it degrades norepinephrine, the fat burning hormone.

7.  Cinnamon.  Swirl your green tea with a stick of cinnamon.  Cinnamon regulates blood sugar levels which in turn will reduce your cravings and stop you feeling sluggish mid afternoon.

8.  Chillies and Peppers.  Another negative calorie source.  Capsaicin is a compound found in chillies and peppers which helps protein structures in the body to break down fat.  The hotter the better, just be careful!

9.  Grapefruit.  This is one you need to be "wary" of in some cases.  Grapefruits have been found to lower insulin levels in the body which stops you from storing more fat.  Just be careful as grapefruits can stop the proper absorption of certain medicines.

10.  Tomatoes.  Deliciously ripe and bright red they are packed with vitamin C an lycopene, a brilliant antioxidant which helps the oxidation process.  Don't peel them as the lycopene is found just beneath the skin.

11.  Eggs.  Supreme quality protein, forget about all the high cholesterol bad press they've had for years - dietary cholesterol does very little to effect cholesterol levels in the body.  The protein in eggs will keep you feeling fuller, so an omelette for breakfast is a great way to get up and go!

12.  Flaxseeds.  As with oily fish, flaxseeds are packed full of Omega-3 fatty acids.  They attract toxins in the fat deposits of the body and help with their elimination.

13.  Nuts.  Glorious nuts.  High calorie but very healthful.  Raw nuts are very nutritious and are a great source of magnesium which helps boost your mood.  Nuts help control weight, reduce heart disease and also diabetes.  A study found that people who ate a handful of nuts 3-5 times a week, lived longer than those who didn't.

14.  Broccoli.  Another one of my favorites.  Lightly steamed and drizzled with a little melted butter... yum!  Packed with fiber, sulforaphane and calcium, this is a superfood.  Eat as much as you want, there is nothing bad to be said for broccoli.

15.  Quinoa.  I have re-discovered this recently.  I tried it once years ago and was not impressed, but recently I found the most amazing salad recipe using quinoa as a base and I have been converted.  Gluten free, quinoa is packed with lots of vitamins and also has a lo GI score so your glucose levels will remain stable.

16.  Lentils.  High in fiber which stops your glucose levels taking a nose dive, they will also keep hunger at bay.  They are also high in iron, but you will need to eat them with tomato to better absorb the iron content.

17.  Bananas.  The starch found in bananas turns into a fatty acid in the gut which metabolizes fats and helps decrease obesity.  They are also high in potassium and tryptophan so can help with depression.

18.  Spices.  Variety is the spice of life, but spicing up your food can help your waistline.  Cayenne is a hot spice but it helps lower blood glucose levels and reduces the risk of excess insulin storing fat.  Turmeric is the highest known sources of betacarotene which is a powerful antioxidant and protects the liver from free radical damage.

So, there you have it.  Now you can get on with eating your way to the body you've always wanted.

Feeding the menopause

This week I have received a special request from a dear, and very talented friend of mine; María José Sesma (if you don't know her you really should check her out, she's incredible!).  MaryJo has asked me to help with nutrition during the menopause, so for all of you facing this new time in life, here are some suggestions I hope will help you through.

The menopause is a highly challenging time of life as it brings many changes with it, and not many of them are welcomed.  Common symptoms include hot flushes, sweating, insomnia, anxiety, impairment of memory, fatigue, fluctuating emotions and weight gain.  There can also be long term consequences which include a decrease in libido, osteoporosis, heart disease and even dementia which are all linked to a reduction in estrogen levels.

The menopause is an unavoidable stage in life which can be a relief for many and a horror for others.  A woman's ovaries stop releasing eggs at some time in her early 50s, and because of this her menstrual cycle will stop.  All the physiological changes she will begin to experiment are largely due to the decrease in estrogen production and the effect this has on other hormones.  Estrogen helps to lift a woman's mood so, when levels drop, she may feel depressed.

Hormone Replacement Therapy (HRT) is available, but some women prefer to try natural remedies or both!  One certainly doesn't interfere with the other so here are some of the natural remedies you might like to consider.

Fatigue:
Avoid foods high in sugar and simple carbohydrates, these cause sharp increases in blood sugar levels but are followed by a sharp dip which can leave you feeling even more tired than you were before.  A better option would be fresh fruit (not juice) or raw nuts.

Hot Flushes:
This is probably one of the worst effects of the menopause.  They pounce when you least expect it and usually when you have just done yourself up for an evening out and the sweat leaves you with your mascara half way down your cheeks and unsightly sweat marks on your smart clothes!  No fun at all...  Stop eating foods that are likely to set off or worsen hot flushes and night sweats such as spicy foods, and other stimulating foods such as coffee, alcohol and chocolate.

Dry Skin:
This is a side effect of the decline in hormones, up your intake of legumes, nuts and seeds such as sunflower, pumpkin and almonds which contain vitamin E, zinc and calcium.  These highly nutritious foods also contain oils which help prevent dry skin and normalize hormone levels.

Depression and Irritability:
Here tryptophan is your friend.  Tryptophan is an essential amino acid which is a precursor to serotonin - the happy hormone.  Serotonin helps moods and may even control sleep regulation and appetite.  Tryptophan rich foods are:
  • Seeds and Nuts
  • Soy Foods - but make sure they are FERMENTED soy foods
  • Cheese
  • Lamb, beef, pork and game
  • Chicken and Turkey
  • Fish
  • Shellfish
  • Oat Bran and Oats
  • Beans and Lentils
  • Eggs
There are tryptophan supplements available on the market, however, it would be convenient to carry out a specific blood test to check your amino acid levels before supplementing.

Also, you would be wise to not skip a meal, this way you will keep your blood sugar levels balanced which also contributes to less emotional imbalances.

Anxiety:
Many women find themselves suffering from anxiety when they reach menopause without any apparent reason.  Here you may find it helps to increase your intake of cashew nuts, almonds, cranberries, acai berries and maca root.

Bone Health:
Menopause is a great time for osteoporosis to strike so you really need to be conscious of getting enough calcium.  Now, I am definitely not one to recommend dairy produce in large quantities as it can be counter-productive as far as bone health goes.  Certain foods produce acidity in the body which means the body releases calcium from the bones to lower the acidity level in the body.  So,  you need to increase your intake of alkaline foods such as vegetables (especially green leafy vegetables and broccoli), fruits, seeds, nuts and yogurts.  Also eat foods that are high in magnesium and boron, these are minerals are important for the replacement of bone and therefore help to lower the risk of osteoporosis, such as; apples, pears, grapes, dates and raisins, legumes and nuts.  You may also like to consider a calcium supplement but make sure it also contains magnesium, vitamin E, D and zinc.  It is also very important to exercise as much as possible, especially weight-bearing exercises; walk, run, skip, jump, dance, lift weights...

A big NO NO for bone health is drinking too much caffeine and smoking and you should reduce your intake of sodium and animal protein.  We eat far too much animal protein, you really only need a piece the size of your palm without the fingers and the same thickness as your palm and not at every meal.  So up your intake of veggies and reduce your animal protein intake.

Other helpers:
However, there are other things you may find helpful, supplementing with Evening Primrose Oil is said to relieve the hot flushes and other symptoms of the menopause - several women I know swear by it.  Yoga... yoga is good for just about everything but the exercise and muscle strengthening it provides are brilliant and the health benefits of meditation are second to none.

I hope this is of help!

What Coke does to you... and it ain't pretty...

Last week The Renegade Pharmacist published an infographic on what a can of Coke does to you after just one hour.  It is stunning to think what your body goes through from drinking just ONE can of Coke.  Well this week The Renegade Pharmacist is back with the effects of drinking a DIET COKE.  So, just in case you missed it, here are both.

What happens one hour after drinking a can of Coke (The Renegade Pharmacist).

1.  First 10 minutes.
10 teaspoons of sugar hit your system (100% of your recommended daily intake).  You don't immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavor allowing you to keep it down.

2.  20 minutes.
Your blood sugar spikes, causing an insulin burst.  Your liver responds to this by turning any sugar it can get its hands on into fat.  (There's plenty of that at this particular moment).

3.  40 minutes.
Caffeine absorption is complete.  Your pupils dilate, your blood pressure rises, as a response your liver dumps more sugar into your bloodstream.  The adenosine receptors in your brain are now blocked preventing drowsiness.

4.  45 minutes.
Your body ups your dopamine production stimulating the pleasure centers of your brain.  This is physically the same way heroin works, by the way.

5.  60 minutes.
The phosphoric acid binds calcium magnesium and zinc in your lower intestine, providing a further boost in metabolism.  This is compounded by high doses of sugar and artificial sweeteners also increasing the urinary excretion of calcium.

6. 60 minutes.
The caffeine's properties come into play.  (It makes you have to pee).  It is now assured that you'll evacuate the bonded calcium, magnesium and zinc that was headed to your bones as well as sodium, electrolyte and water.

7. 60 minutes.
As the rave inside of you dies down you'll start to have a sugar crash.  You may become irritable and/or sluggish.  You've also now, literally, pissed away all the water that was in the Coke.  But not before infusing it with valuable nutrients you body could have used for things like even having the ability to hydrate your system or build strong bones and teeth.

Now this is me... Lucy Carr... we all know that drinking regular soda is full of sugar and is bad for us but people still drink vast amounts.  After reading this, will you be switching to Diet Coke?

Probably not, because as I said before, The Renegade Pharmacist has, this week, published the effects of drinking Diet Coke and here it is, in his own words.

What happens one hour after drinking a can of Diet Coke (The Renegade Pharmacist).

1.  First 10 minutes.
TRICKS YOUR TASTE BUDS & ATTACKS YOUR TEETH
The phosphoric acid attacks the enamel in your teeth, while the artificial sweeteners like aspartame hit your system.  Aspartame may trigger taste receptors and trick your body into thinking it has just processed sugar.

2.  20 minutes.
CAN SWITCH ON FAT STORAGE MODE
Like regular Coke this can trigger insulin, which sends your body into fat storage mode.

Data from a number of studies, including the Nurses' Health Study and the Health Professionals Follow-Up Study also reported greater risk of type 2 diabetes, high blood pressure and heart disease.

Also some data indicates those who consume artificially sweetened beverages double the risk of metabolic syndrome which is related to diabetes and cardiovascular problems.

3.  40 minutes.
CAN CAUSE ADDICTION
The potentially deadly combination of caffeine and aspartame creates a short addictive high similar in the way cocaine works.  Excitotoxins are released which may exhaust your brain by overstimulating it's neuroreceptors, especially if consumed on a regular basis.

4.  60 minutes and beyond
CAN DEPLETE NUTRIENTS, MAKE YOU HUNGRY & THIRSTY FOR MORE
Unlike the small amount of satisfaction you get from regular coke, your body may still crave sweets.  This makes you likely to reach for another soda, or worse, some other junk food you consider to be safe and the cycle continues.

A can of diet coke provides no nourishment and would replace a more nutritious drink you could have drunk while potentially depleting your body of essential minerals.

It will never quench your thirst as it dehydrates rather than hydrates your body.  A lack of vital water can lead to brain fog, poor concentration, fatigue and feeling irritable.

Now, back to me, Lucy Carr.  I was so horrified of the possible side effects of aspartame consumption that I quit Diet Coke in September 2013 and I haven't had a soda, regular or diet since - that's almost 2 years and yes, I feel so much better for it and I don't have a problem controlling my weight anymore.

So, as always, I hope this information will help you make an informed decision about improving your health.
