- Description
- Aim: To quantify the insulin requirement for a high‐protein meal compared with a low‐protein meal, controlling for carbohydrate and fat content. Methods: In this crossover study, young people with Type 1 diabetes were randomized to consume a high‐ (60 g) or low‐protein meal (5 g), each containing 30 g carbohydrate and 8 g fat. A variation of the insulin clamp technique was used to determine the insulin requirements to maintain euglycaemia for the following 5 h. Results: A total of 11 participants (mean ± sd age 16.5 ± 2.7 years, HbA1c 52 ± 8.7 mmol/mol [6.9 ± 0.8%], diabetes duration 6.9±5.1 years) completed the study. The mean insulin requirements for the high‐protein meal were higher than for the low‐protein meal [10.3 (CI 8.2, 12.57) vs 6.7 units (CI 4.7, 8.8); P =0.001], with inter‐individual requirements ranging from 0.9 to six times the low‐protein meal requirement. Approximately half the additional insulin [1.1 units/h (CI 0.5, 1.8; P =0.001)] was given in the first 2 h, compared with an additional 0.5 units/h (CI –0.2, 1.2; P =0.148) in the second 2 h and 0.1 units (CI –0.6, 0.8; P =0.769) in the final hour. Conclusions: A high‐protein meal requires ~50% more insulin to maintain euglycaemia than a low‐protein meal that contains the same quantity of carbohydrate. The majority is required within the first 2 h. Inter‐individual differences exist in insulin requirements for dietary protein.
