Understanding the science behind starch, blood sugar, and sustainable change
When it comes to managing diabetes through diet, it’s not just about cutting out sugar. It’s about making strategic choices — especially when it comes to starchy carbohydrates like rice, bread, potatoes, and pasta.
The Diabetes Improvement Programme (DIP) takes a balanced, evidence-informed approach. One of its core principles is simple: limit starchy carbohydrates to just one meal a day. At first glance, this may sound restrictive — but there’s solid science behind it. And more importantly, it works.
Here’s why this one-meal rule matters — and how it can help you take meaningful control of your blood sugar and long-term health.
What Are Starchy Carbohydrates?
Starches are complex carbohydrates found in foods such as:
- Rice, pasta, and noodles
- Potatoes, sweet potatoes, and yams
- Bread, crackers, and baked goods
- Corn, peas, lentils, and beans
Although they’re often considered “slow release”, these foods can rapidly break down into glucose in the body — especially when eaten in large quantities or refined forms. This causes a rise in blood sugar levels — precisely what individuals with diabetes or insulin resistance aim to manage.
The Problem With Overdoing Starch
When starchy foods are consumed at every meal, they can:
- Spike blood sugar levels multiple times a day
- Increase insulin demand, placing extra strain on the pancreas
- Lead to weight gain or make weight loss more difficult
- Contribute to energy crashes and cravings later in the day
For those with Type 2 diabetes or prediabetes, this daily glucose rollercoaster can make management difficult and may even undo the benefits of other healthy habits.
Why One Starchy Meal Works Better
By limiting starch to just one meal per day, the DIP plan allows the body to:
- Stabilise blood sugar levels more effectively throughout the day
- Lower overall insulin exposure, which supports weight loss and improves insulin sensitivity
- Improve energy levels without the post-meal slump
- Break the dependency on carbohydrate-rich meals for satiety or satisfaction
This strategy doesn’t eliminate carbs — it simply creates a rhythm where your body has time to reset and burn fat more efficiently between meals.
It’s Not About Elimination — It’s About Moderation
Let’s be clear — starch is not the enemy. Many starchy foods are part of cultural traditions, family meals, and emotional comfort. The DIP framework respects that. By allowing starch at just one meal a day, it encourages mindful moderation rather than extreme restriction.
This flexibility helps make the plan more realistic, sustainable, and enjoyable — which is key for long-term change.
How to Make the Most of Your One Starchy Meal
If you’re choosing to include starch, here are a few tips:
- Pick whole, minimally processed options — such as brown rice, millet, or sweet potato
- Mind your portions — one cup (about the size of your fist) is a helpful guide
- Pair it with protein, fibre, and fat — this slows digestion and helps reduce glucose spikes
- Make it the highlight, not the base — build your plate with vegetables and protein first
For example:
A lunch of grilled chicken, mixed salad, and a small portion of brown rice is more balanced than a heaping plate of pasta with little else.
Science Meets Simplicity
The concept of one starchy meal per day is backed by research in low-carb and moderate-carb interventions for Type 2 diabetes. Numerous studies show that reducing daily carbohydrate load (especially starchy carbs) improves HbA1c, supports weight loss, and enhances metabolic markers like triglycerides and insulin sensitivity.
By following this simple principle, you’re not just adopting a diet — you’re creating better metabolic conditions for your body to heal and thrive.
Small Change, Big Impact
You don’t need to give up rice forever. You don’t need to avoid bread at every meal. But choosing to have starch just once a day could be the difference between constantly battling blood sugar fluctuations and finally finding control.
This one shift — this small act of moderation — can ripple out into better energy, clearer thinking, improved lab results, and a more empowered relationship with food.
And in the end, that’s what the DIP plan is all about — progress, not perfection.

How often do we acknowledge the silent hero inside us—our liver? On World Liver Day, it’s time to give this powerhouse organ the attention it deserves. Quietly working 24/7, your liver keeps you healthy, energised, and toxin-free—yet we often notice it only when something goes wrong.
Festive celebrations like Easter, Christmas, birthdays, or long weekends are often filled with joy, family, and… food. Lots of it. But while these occasions are meant to be enjoyed, they also tend to lead to unwanted weight gain—with many people putting on an average of 7lbs during festive periods, which can take months to lose, if it comes off at all.
Chronic Kidney Disease (CKD) affects millions globally and is one of the leading contributors to long-term health complications and premature deaths. CKD is marked by a gradual loss of kidney function, and in advanced stages, it can result in the build-up of fluids, toxins, and electrolytes—putting immense strain on the body.
