Managing Diabetes : Is Cutting Sugar Alone Enough for Diabetics? Dr Chan Answers

Diabetes management - what diabetics should do.

No. Cutting down sugar intake alone is not enough for diabetics. It is the first and most obvious step. But it is far from the only one. And in my experience coaching people with diabetes, stopping at addressing sugar intake is one of the most common I see many diabetics make. Holistic and optimal diabetes management requires a lot more than that.

In this video, I address one of the most common misconceptions I encounter among people with diabetes.


The Most Common Mistake I See in My Patients

When people are first diagnosed with diabetes, or when they decide to take their diabetes seriously, the first thing almost all of them do is cut down on sugar. They stop taking sugar in their drinks. They put down the sweets and the cakes. They swap their sugary desserts for something they think is safer.

That is a good start. But then they stop there. They think the job is done. They reduce their sugar intake, they monitor their blood sugar numbers, and if the numbers look acceptable, they conclude that they are managing their diabetes well.

I often see patients who have been doing exactly this for years. Their blood sugar may be reasonably controlled. But their diet is still poor in other ways. Their weight has not improved. Their blood pressure is not well managed. Their sleep is terrible. They are chronically stressed. And they wonder why, despite cutting sugar, their diabetes is not improving the way they hoped. Some are still progressing toward complications.

Cutting sugar is necessary. It is far from sufficient.


Diabetes Is Not a Sugar Intake Problem. It is a Sugar Regulation Problem Caused by Unhealthy Lifestyle Habits.

This is the heart of what I want every diabetic to understand. Diabetes is not simply a disease caused by eating too much sugar. It is a disease caused by multiple factors across your entire lifestyle and diet that leads to problems with sugar regulation.

When we only address sugar intake, we are not addressing all the underlying causes of the problem.

Eating habits is a good place to start. But eating habits that go far beyond sugar. The total carbohydrate intake. The types of carbohydrates. The portion sizes of every meal. The timing of meals. The balance of food groups. The amount of dietary fibre. The quality of fats consumed. Every one of these aspects of diet matters for diabetics. And every person with diabetes is different. The specific changes that matter most for one person are not necessarily the same for another.


Beyond Diet: The Lifestyle Habits That Diabetics Underestimate

After eating habits, the next thing people think of is exercise. And they are right to think of it. Physical activity is important for diabetes management. But It is not just about going to the gym or going for a run. It is about the total level of physical activity throughout the day. It is about how much time you spend sitting. It is about whether you move after meals. These things all influence blood sugar and insulin sensitivity in ways that a weekly gym session alone cannot compensate for.

And then there are two more lifestyle habits that diabetics consistently underestimate.

Sleep. And stress.

Poor sleep raises blood sugar. It disrupts the hormones that regulate appetite and metabolism. It makes it harder to make good choices the next day. Many of my patients with poorly controlled diabetes are also people who sleep badly. The two are connected.

Stress raises blood sugar directly. The stress hormones, particularly cortisol, cause the liver to release glucose into the bloodstream. This happens regardless of what the diabetic ate that day. A person who has been careful with their diet but is living under chronic stress can still find their blood sugar stubbornly elevated. And the vicious cycle cascades. Poor control leads to anxiety about the numbers. That anxiety is itself a stressor. And the cycle continues.

Can you see what is happening here? Cutting sugar alone does not touch any of this.


The Question Every Diabetic Should Be Asking

Most diabetics ask: "How do I lower my blood sugar?"

That is a reasonable question. But it is not the most useful one.

The more useful question is this: "What are all the aspects of my lifestyle and diet that are affecting my diabetes, and which of them need to change most urgently for me, specifically?"

Every person with diabetes is different. Their health history is different. Their eating habits are different. Their lifestyle is different. The changes they need to make are therefore different. This is why I work closely with each patient to identify the specific areas that need the most attention, not just hand them a generic list of dos and don'ts.

If you have diabetes, I want to encourage you to look at your lifestyle holistically. Not just your sugar intake. Your entire diet. Your physical activity. Your sleep. Your stress. All of it matters. All of it influences your outcomes.

Start now. Start today. Do something beyond just cutting sugar.

About This Video

In this video, I tackle one of the most common and costly misconceptions among people with diabetes: that cutting down on sugar intake is all they need to do. I explain why cutting sugar is a necessary first step but not the only one, and walk through the four lifestyle areas that every diabetic must address: eating habits broadly, physical activity, sleep, and stress management. My goal is to help diabetics see their condition holistically and take the right, complete action.


Full Transcript

The following is the full transcript of the video above.

Combating diabetes through lifestyle habits is more than just reducing the intake of sugar. Let's talk about this on this episode of The Daily Dose. Do you have diabetes, or do you have family members who have diabetes? Or maybe you are just generally concerned about diabetes and want to do everything that you can to prevent diabetes.

If you are any of the above, this video is for you. Watch on.

Hi, guys. Welcome back. If you're new here, I am Dr. Chan. I'm a medical doctor from Singapore. In my work, whether as a medical doctor or as a trainer and coach, I often deal with people with diabetes, and one of the very common misconception amongst people with diabetes is this, that many of them think that all they need to do in terms of lifestyle change is simply to cut down the intake of sugar in their diets.

So what do you think? Is cutting down the intake of sugar the only thing that people with diabetes need to do? What about other lifestyle habits? What other lifestyle habits do you think are also important in combating diabetes? Type your response in the comments section below. So what was your answer?

What are the other lifestyle habits that would influence the health outcomes of people with diabetes? What was your answer? Here's my answer. Cutting down one's intake of sugar is an obvious first step, but it is not the only lifestyle habits change that people with diabetes need to do. For people with diabetes, eating habits change is a no-brainer, a must-do, regardless of whether they are already on medications or not, regardless of whether their blood sugar is already well controlled or not.

Eating habits change and improvement is critical in winning the battle against diabetes in the holistic sense, beyond just achieving good blood sugar numbers. But eating habits change and improvement for people with diabetes is more than just cutting down sugar intake. There are many aspects of one's eating habits beyond just sugar intake that would determine the eventual health outcomes of people with diabetes, especially with regards to preventing and combating the many complications of diabetes, which is actually the main, one of the most important goals of people with diabetes.

Therefore, people with diabetes should work closely with their doctors to identify areas in their diet, aspects of their eating habits that needed changing and improving. From my experience in coaching diabetic patients to make dietary habits change, every diabetic patient has different health and medical conditions, and they also have different eating habits.

So the change that they need to make are also different. So we must go beyond just a generic, "Take less sugar, exercise more," kind of approach to lifestyle change for people with diabetes. It is important to identify areas of eating habits change that are more critical and specific to each individual, specific to each patient with diabetes, and then equip them and coach them to make the necessary changes.

So people with diabetes must go beyond just cutting down their sugar intake. They should work closely with their doctors to identify specific areas of their diets to change and to improve. So beyond eating habits, what other lifestyle habits are important for people with diabetes? What do you think?

What was your answer just now? Exercise. Exercise is the next obvious one when it comes to health and especially in combating diabetes. But we must also look beyond what people generally define as exercise, such as running or going to the gym. We must actually look at the entirety of one's lifestyle and habits that would impact one's level of physical activity every single day.

So, so far, we have only covered two lifestyle habits that are important for people with diabetes, the two common and obvious ones, diet and exercise. And because I want to keep each episode of The Daily Dose bite-size, I think we only have enough time to just briefly mention another two more lifestyle habits that are important for people with diabetes, and then cover them in greater detail in future episodes of The Daily Dose.

So beyond exercise and diet change, what are two other lifestyle habits that you think are important for people with diabetes? If I were to choose, I would choose sleep and stress-related habits. People with diabetes tend to underestimate the impact that their sleep habits, stress levels have on their health, especially with regards to their risk of developing complications of diabetes in the future.

So in this episode of The Daily Dose, I hope I have highlighted that reducing one's sugar intake is not the only thing that people with diabetes need to do. It is the first and obvious thing. If they want to win their battle against diabetes, they must do more than that. People with diabetes should look at their lifestyle habits holistically and identify specific areas of improvement, especially in the areas of diet, exercise, sleep, and stress management. I'm Dr. Chan, and I am on a mission to awaken people to the power of habits. Take care, and have a blessed day.
