How a simple 'fibre first' rule is transforming type 2 diabetes management

Emerging nutritional research is transforming traditional Indian dining habits by suggesting that the order in which food is consumed is as vital as the ingredients themselves.

A 2025 study published in the Asia Pacific Journal of Clinical Nutrition demonstrated that patients with type 2 diabetes who prioritised vegetables over carbohydrates saw their HbA1c levels drop from 8.3% to 6.8% over two years.

Experts suggest that by sequencing fibre and protein before starches, diners can effectively soften blood sugar spikes and eliminate the common "4pm slump" without restrictive calorie counting.

The science of the sequence

Eating fibre first creates a natural buffer in the gut, which slows the absorption of glucose. Prateek Kumar, nutritionist and founder of Fitcru, explains that this order ensures carbohydrates arrive when the body is prepared to handle them.

“Eating vegetables first slows digestion because fibre forms a natural buffer in the gut,” he says. Veena V, chief clinical dietician at Aster Whitefield Hospital, adds that this strategy improves satiety, meaning individuals naturally desire smaller portions of rice or roti.

Practical steps for the plate

• Prioritise fibre: Begin every meal with raw salads or low-starch cooked vegetables like cabbage or French beans.
• Integrate protein: Follow with dal, paneer, eggs, or meat, as “eating protein after fibre improves fullness and supports metabolic function,” according to Kumar.
• Conclude with carbohydrates: Limit rice or roti to a palm-sized portion at the end of the meal to prevent sharp insulin spikes.
• The preload strategy: For one-pot meals like khichdi or poha, Kumar recommends a "preload" of a small bowl of salad or a glass of chaas before eating.
