The Great Ormond Street Diet  

 

 

 

This is an alternative version of the MCT diet, based on fat and energy exchanges. The child's energy requirement is derived from 30% MCT, 30% long chain fat, counted as 15g fat exchanges and 40% from other foods, counted as 100kcal exchanges.

Construction of diet

The diet is composed of four parts:

The diluted Liquigen can be flavoured with artificial sweetener, coffee, tea, low calorie squash, spices (e.g. cinnamon), flavouring essence (e.g. vanilla) or an allowance of skimmed milk can be calculated. Fat present in the calorie exchanges is not counted as part of the fat allowance. An example of this type of diet is shown in Table 6

Table 6 Great Ormond Street ketogenic diet

Estimated energy requirement - 1500 kcalories  
55g MCT = 110 ml Liquigen (diluted to 220 ml with water) = 457 kcal
3 5 x 15g fat exchanges = 473kcal
6 x 100 kcal calorie exchanges = 600 kcal
Total = 1530kcal
