How to manage Type 2 diabetes: focus on what matters most
How to manage Type 2 diabetes: focus on what matters most
One question I ask all my dietetic students is:
“If your patient walks out of your outpatient consultation and does one thing, what would be the most important thing for them to do?”
It’s a question I think is equally useful for people managing Type 2 diabetes.
There are so many things we’re told to consider: what to eat, what foods to avoid, how much carbohydrate to have, how to read food labels, when to exercise, whether to lose weight and which approach is best. All of these may have a role. But with so much information and advice, it’s easy to get distracted by the details and lose sight of what will make the biggest difference. If you’ve just been diagnosed, my newly diagnosed guide is a good place to start.
By narrowing down what matters most, we can focus our attention and effort on the changes likely to have the greatest impact.
What makes the biggest difference in managing Type 2 diabetes?
It depends on the individual. For many people with Type 2 diabetes who are carrying excess weight, weight loss can have a significant impact on glucose management, insulin resistance and other cardiovascular risk factors. For others, the priority might be improving the nutritional quality of their meals, being more physically active, developing regular eating habits or better understanding how their food choices affect blood glucose levels.
There isn’t one change that’s equally important for everyone. That’s why I spend time understanding what someone is currently doing, what they’d like to achieve and what’s realistic for them.
The best approach is the one that works for you
There are many different ways to manage nutrition, weight and diabetes. Some people prefer a structured eating plan, while others do better making gradual changes to their usual meals.
One of the most common questions I’m asked is which approach is best. My answer is that what works for one person may not work for another. It needs to fit their lifestyle, food preferences, culture, health needs and circumstances. It also needs to produce meaningful results, and be something they can maintain.
For example, someone may lose weight on a particular eating plan, but if it’s hard to follow over time, keeping the weight off becomes the bigger challenge. That matters with a long-term condition like diabetes.
Focus on what you do most of the time
Clients often tell me:
“I never eat takeaway, eat cake or drink alcohol.”
My response is usually:
“I’m less concerned about what you don’t do, or what you do infrequently. I’m more interested in what you do most of the time.”
That tells me much more about someone’s usual eating pattern. What are they eating for breakfast and lunch most days? Are they including enough vegetables, fibre and protein? Are their meals satisfying? What happens when they’re busy, tired or have nothing planned for dinner?
It’s these everyday habits that often offer the greatest opportunities. Regularly adding vegetables and protein to meals, replacing sugary drinks or cutting back on frequent unplanned snacking may have more impact than worrying about an occasional piece of birthday cake. (More in Do you need a perfect diet for Type 2 diabetes?)
Don’t get caught up in the small details
Is it better to exercise in the morning or evening? Should you choose one type of bread over another? Is there an ideal time to eat dinner?
These can be worthwhile questions, but sometimes people spend so long looking for the best answer that they never make a change. I often see this with exercise. Someone is unsure about the best time of day, and in the process of deciding, they end up doing very little. For most people, regular physical activity that fits their routine will make a greater difference than finding the perfect time.
The same applies to nutrition. Rather than asking whether one food is marginally better than another, ask whether your overall eating pattern is supporting your health. Sometimes the simplest change is the most useful place to start.
Choose a change that makes a meaningful difference
When considering where to begin, I encourage people to ask three questions:
What would make the biggest difference to my health or diabetes management? Consider your current challenges, health priorities and usual habits.
What am I realistically able to change? Look for something that fits your lifestyle and that you feel confident working on.
How will I know if it’s helping? Depending on your goal, that might be glucose levels, weight, physical activity, eating patterns or how satisfied you feel after meals.
For example, if you regularly skip lunch and spend the afternoon snacking, improving lunch might be a useful starting point. If you’re relatively inactive, adding a regular walk might be more valuable than debating which exercise program is best. And if weight loss is an important part of your diabetes management, finding an eating approach that helps you achieve and maintain it may be the priority. If you take a GLP-1 medication, it’s often protein, eating enough and building habits you can keep. See my GLP-1 nutrition support page.
Once you’ve made a change and seen how it’s working, you can decide what to focus on next.
What happens after you’ve made progress?
Making a change is one part of the process. Maintaining it is another. For someone who has lost weight, preventing regain may become the next priority. For someone who has improved their glucose levels, the focus might shift to maintaining those results or addressing another part of their health. Priorities change, and it’s worth reviewing them as you go. (See How to build healthy habits that last with Type 2 diabetes.)
This is something I regularly discuss with clients: what’s working, what’s proving difficult, and which changes are worth continuing or adjusting. Diabetes is a long-term condition, and we need solutions that work over the long term.
So, what matters most for you?
There will always be more information about nutrition, new dietary approaches and different ways to manage diabetes. Some will be useful, and others less relevant to your circumstances. Before making another change to your diet or exercise routine, ask yourself:
“Of all the things I could change, which one is likely to make the biggest difference?”
That’s often a very useful place to start.
