Do you ever glance at the carbohydrate count on a packet of pasta and wonder whether cutting back would suit you? In my practice as a diabetes nutritionist, I meet many people who feel overwhelmed by diet advice and want a clear, realistic way of thinking about it. Low-carbohydrate eating has attracted a lot of attention, so let us look at what it involves and who it might not suit.
What is a low-carbohydrate diet?
There is no single definition. In general, low-carb eating means reducing foods such as bread, rice, potatoes, sugary drinks and fruit juices, and leaning more on protein, healthy fats and non-starchy vegetables. How far people go varies a great deal, and the evidence behind different versions is not the same.
What it might do for some people
Carbohydrates are the main influence on blood glucose after a meal, so eating fewer of them can mean a smoother response for some people. Research suggests a few potential advantages:
- Satiety: more protein and fibre from vegetables can keep you fuller for longer.
- Weight: cutting back on refined carbohydrates often lowers overall calorie intake, which some find helpful.
- Cravings: fewer sugary snacks can mean fewer sugar-driven highs and lows in energy.
The evidence is strongest for type 2 diabetes. For type 1 diabetes, carbohydrate awareness is more complex and any experiment with low-carb eating needs to be coordinated with your diabetes care team.
Risks and things to consider
Low-carb eating is not without drawbacks, and cutting carbohydrates sharply may lead to:
- Nutrient gaps, such as less fibre and fewer vitamins found in wholegrains and fruit.
- Tiredness, headaches or constipation in the early days, sometimes called the “low-carb flu”.
- An eating pattern that feels hard to keep up, which can lead to a cycle of strict phases and giving up.
It also matters if you take diabetes medication. I work alongside your doctor, who leads on any medicines and how your diet changes might affect them, so please do not alter anything about your tablets or insulin on your own.
Practical, gentle ways to explore
- Swap refined grains for fibre-rich options such as bulgur, oats or whole-grain bread in sensible portions.
- Fill half your plate with non-starchy vegetables like broccoli, spinach, peppers and courgettes.
- Include protein with meals, from fish, poultry, eggs, legumes or tofu.
- Add healthy fats such as olive oil, avocado, nuts and seeds.
- Keep a short food diary for a couple of weeks to see how you feel after different meals.
In my experience, a gradual change works better than an abrupt cut. You could start by replacing one refined-carb meal a day with a vegetable-and-protein-based one, then build from there. I also help clients link this with other goals, such as weight loss and gut health, and many people ask whether they can eat fruit with diabetes when they cut back.
Ultimately, the right approach depends on your preferences, lifestyle and health background. If you are tired of cutting out staple foods and still feel unsure, generic carb rules will only take you so far.
