There is No Defence for Sugar

Sugar has been touted as the main culprit for the obesity epidemic we are currently living through. However fat has long been the enemy of governmental advice, and is often touted as the reason for obesity. So says a recent article in the Guardian.

It seems that a storm is gathering over the current dietary advice from the government.


This week the BMJ has published its front cover with the title ‘Is Sugar the Real Culprit in the Obesity Epidemic’. This is not news for a lot of us, however now that major medical bodies are starting to recognise the detrimental impact of sugar, maybe the government will be able to do something about it.

The writer also expressed that the quality of food we are eating is not the only cause for the rise in obesity, but the nature of the way we eat now. The much criticised ‘TV Dinner’ is apparently a cause for the rise in obesity as people are cooking quick and easy meals that are full of sugar. Dr. Malhotra is advising his patients to cook natural food, and to not place any significance on high-fat or low-fat but to concentrate on limiting the sugar consumed during the day.

A patient had visited Dr. Malhotra for a cardiovascular examination. The patient was baffled as he had gained a stone despite having been following a low fat diet at the recommendation of his dietician. He has told that this diet would help reduce his blood cholesterol level.

As research methods and techniques are progressing, so is our understanding of food and nutrition. We no longer ostracise fat like we have in previous decades. In fact recent research has shown that natural saturated fats like those found in dairy products may actually protect us from strokes and heart disease.

BMI – Perhaps not as accurate as we are lead to believe

Have you relied on the body mass index (BMI) to work out if you are a healthy weight? Well if you are short we have some bad news for you. A recent article in The Daily Mail has explained that Nick Trefethen of Oxford University’s Mathematical Institute believes that the body mass index formula, traditionally used to work out if someone is overweight is flawed. To combat this he has come up with his own formula, and his favours tall people.




He has found that taller people are not as overweight as they are being told. This is due to the BMI underestimating how much natural bulk taller people have. As a result it also overestimates how much natural bulk smaller people have.

The BMI formula is currently used by doctors throughout the UK to work out if someone is overweight or obese. This also determines if they are at risk of weight related conditions such as high blood pressure, heart disease and diabetes.

BMI is calculated by dividing weight in kilograms by height in metres squared. A mark of 30 or greater means a person is obese, 25-29.9 is overweight, 18.5-24.9 is a normal weight range and <18.5 is underweight.

Nick Trefethen’s new version calculates BMI by weight in kilograms multiplied by 1.3. The answer is then divided by a person’s height to the power of 2.5, rather than height squared. The professor feels that the new results could affect millions of people. The Telegraph website has an interactive that shows the difference the new system will make to your BMI.

At The Natural Ketosis Company we do not like to use BMI, as it does not distinguish between muscle and fat mass. Muscle weighs more than fat so you could be as fit and muscly as a rugby player but technically be obese.

The highest rated comment on the Daily Mail has said exactly that:



Unlike many other diets, when you lose weight with The Natural Ketosis Programme you will lose fat, not muscle mass, as our foods are high in protein, ensuring that muscle mass is maintained. As muscle weighs more than fat you may find that you are losing inches and your clothes feel looser but you are not losing as much weight.

We aren’t sure about you, but we prefer to see the difference in our body shape by the way we feel and in the fit of our clothes, rather than on a set of scales.

How do you feel about the BMI, have you used it in the past and will you continue to use it?
