Oh, good day and welcome to Day 14!

Well done on reaching the end of week two of your 28-day challenge! Over the past two days, I’ve talked about cholesterol and blood pressure, two of my pet topics. But today, we’re tackling one of my arch-enemies—sugar and heart disease.

Why is Sugar Such a Problem?
Let’s take a moment to travel back in time—three or four million years ago, to the African plains where our ancestors roamed. Do you think there was much sugar available back then? Probably not. Sugar in their diet was likely rare and seasonal, coming from fruits or honey.

We know that sugar is an incredibly rich energy source, so when we consume it, our body reacts the same way it did millions of years ago—thinking, "Wow! What are we going to do with this great energy source?" The answer? Store it.

How Does Sugar Affect the Body?
When we consume sugar, our blood sugar levels rise, triggering the release of insulin. Insulin’s job is not only to regulate blood sugar, but also to store excess sugar in our fat reserves.

Yes, sugar gets converted into fat. If you didn’t know that before, you do now! This process leads to the formation of triglycerides, which are stored primarily around our tummy and internal organs. And that’s where the real problems begin.

The Link Between Sugar, Insulin Resistance, and Disease
Fat storage around the tummy and organs is associated with high insulin levels, which can lead to insulin resistance. This means that when you're exposed to carbohydrates, your body produces even more insulin, making it easier to store fat.

This cycle becomes self-perpetuating—the more insulin resistant you become, the more fat you store, and so on. Over time, this process also triggers inflammation, which contributes to:

Weight gain, which increases blood pressure

Higher triglyceride levels, linked to worse health outcomes

Lower HDL (good cholesterol) levels

Increased risk of coronary artery disease, cancer, and dementia

Where Does It All Go Wrong?
Much of the problem lies in modern diets full of processed foods. These often contain hidden sugars, fueling insulin resistance, weight gain, and inflammation.

What Can You Do?
Stick to whole foods—avoid processed foods whenever possible.

Drink water—it’s the best form of hydration.

Avoid sugary drinks, including fruit juices. Fruit juice is high in fructose, which is processed by the liver and, in excess, can be toxic.

Choose healthy snacks—skip chocolates, biscuits, and cakes, especially if you are insulin sensitive.

Watch your waistline—excess fat storage is a sign of underlying metabolic issues.

Final Thoughts
Be mindful of sugar. Focus on whole, sensible foods, drink plenty of water, and take good care of yourself.

I look forward to seeing you tomorrow. Live as well as possible, for as long as possible. Take care, and bye for now.

Are You at Risk of a Sudden Heart Attack? How Healthy is Your Heart? Really?

Heart disease is the #1 killer in the Western World. In Australia, someone dies every 28 minutes from heart disease. That’s 51 people a day. In the US, someone has a heart attack every 40 SECONDS! Fortunately, many heart attacks are preventable. However, regular exercise and eating healthy are no guarantee you won’t succumb to this silent killer.

94% of Australians have at least One Risk Factor for heart disease.
59% of Australians have been Touched by heart disease.
Yet only 3% of Australians have had a Full Heart-Health Assessment in the past 12 months.

Oh, g'day and welcome to day 14 and well done on getting to the end of week 2 of your 28 day challenge. Well, I think yesterday and the day before I was speaking about cholesterol and speaking about blood pressure and these were two of my pet topics. Well, today we're talking about one of my arch enemies. We're talking about sugar and heart disease. Well, why is that such a problem? Well, let me get you to cast your mind back to our evolutionary past. Let's try and imagine our ancestors three or four million years ago on the African plains. Tell me, do you think there was much sugar there now that you're picturing it? I don't think there was. I suspect sugar came along into our diet infrequently. Maybe quite seasonally. Maybe fruit. Or types of fruit. Even honey. But the point being it was probably infrequent. And we know that sugar is a really rich energy source. So when we consume sugar, our body probably behaves as it did 3 to 4 million years ago. Thinking, wow, what are we going to do with this great energy source that we don't need right now? And of course it tries to store it. So when we have sugar in our bloodstream and a sugar spike, if you like, or sugar registered as increasing in our bloodstream, our body responds to that by producing insulin, which of course regulates our blood sugar levels, but really, really importantly is acting to help store that blood sugar, that sugar in the blood into our storage reservoirs. Us humans, our storage is in fat. So sugar gets converted into fat as part of the formation of triglycerides. Hard to get your head around, but hang in there. The sugar gets converted into fat. Did you know that? If you didn't, you do now. And that triglyceride then gets stored in the fat reserves around our tummy, most commonly. It can also get stored in the fat reserves. around our organs and that's a problem and that sort of fat deposition around the tummy around the organs is related to high levels of insulin which can drive insulin resistance now insulin resistance means you produce more insulin when exposed to carbohydrates so this becomes if you like a spiraling circle a dog chasing its tail the more insulin resistant you are, the more fat you'll lay down if you're exposed to carbohydrate and so on. Now as you build up your fat reserves and in association with insulin and sugar, you drive inflammation as well. Well as you gain this weight, as you try and put that energy in the form of triglycerides into storage, you really drive a number of things which are just obvious. Increased weight will push up your blood pressure. Increased triglycerides in the bloodstream we know are linked with worse outcomes. And increased triglycerides tend to be associated with lower good cholesterol or lower HDL levels. Together with... inflammation and these seem to be linked not only to risk of cancer and dementia but also coronary artery disease well where are the problems probably with our modern day diet and processed foods what can you do probably sticking to whole foods is the best thing try and avoid those processed foods drinking water is a great way to get it get hydration. Avoiding sugary drinks and avoiding probably fruit juices is a good idea because there's a lot of fructose and fructose is a sugar as well. And fructose actually gets caught in the liver and can be in excess, toxic to the liver. So fruit juice is not a great hydration. Water's good. Think about snacks that are not sugary snacks. You know, having a chocolate or a biscuit or a cake, particularly if you're insulin sensitive. It just doesn't make sense. So watch out for the sugars. Watch out for your waistline. Look at whole foods, sensible foods. Drink good water. Avoid sugary drinks. And take care of yourself. I look forward to seeing you tomorrow. I'm going to wish you the very best. I hope you live as well as possible for as long as possible. Take care. And bye for now.

Please Note: Before embarking on the Younger Longer 28-Day Heart Health Challenge, it's essential to consult with your General Practitioner (GP) to ensure it's safe for you to participate, especially if you have existing health conditions or risk factors. Pre-exercise screening is recommended to identify any medical conditions that may increase the risk of adverse events during physical activity.
