Diet is one of the strongest tools for managing Type 2 diabetes (T2D). Eating fewer calories can help the body reduce liver fat, improve insulin sensitivity, and lower blood glucose levels. For some people, major weight loss can even lead to partial or full diabetes remission, meaning blood sugar returns to non-diabetic levels without medication.
In the UK, continuous low-energy diets (CLED) are commonly used for remission programs. These diets provide around 800–900 calories per day and are usually followed for several weeks. But not everyone finds this strict routine suitable.
Intermittent low-energy diets (ILED) offer a different pattern. They use very low-calorie days mixed with normal-eating days, which some people find easier to maintain. Because people live with different habits, workloads, and family demands, understanding diet preferences is important for building effective diabetes care plans.
What the Survey Found
Researchers surveyed 622 adults with T2D to learn how age, health needs, and lifestyle goals influence diet choices.
Key findings included:
Adults younger than 65 were more likely to choose CLED, especially if they wanted:
- Faster weight loss
- Fewer diabetes medications
- More predictable daily routines
ILED was preferred by people who wanted:
- More flexibility in meal timing
- Diets compatible with family meals
- Less pressure during social events
- Occasional higher-calorie days
Diet preference was not only about weight loss. Many participants considered how a diet would impact their blood sugar control, energy levels, hunger, stress, and long-term sustainability.
CLED and ILED Are Not Always the First Choice
Although both CLED and ILED are used clinically, many people preferred moderate-calorie or low-carbohydrate diets instead.
These alternatives appeal because they often:
- Allow normal food instead of shakes or meal replacements
- Help reduce spikes in blood glucose
- Support gradual, steady weight loss
- Fit easily into daily life
Across all diet types, participants said they wanted plans that were:
- Simple
- Easy to understand
- Clear about what foods to choose
- Practical for long-term use
What This Means for Better Diabetes Care
This research highlights the importance of patient-centred care. When healthcare professionals understand why people choose certain diets, they can give guidance that better matches personal needs.
A well-matched diet can help improve:
- Weight management, which reduces insulin resistance
- Blood glucose control, lowering the risk of complications
- Heart health, especially important because T2D increases cardiovascular risk
- Motivation and adherence, leading to better long-term results
Offering choices—rather than a single strict plan—may help more people reach remission or achieve better control of their diabetes.
