Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each subject will undergo 2 study days, in double-blinded, randomised fashion, separated by 3 days. Two days prior to the first study day, subjects will cease taking metformin, if they usually use this drug. On each study day, subjects will be given a test meal ("breakfast"), consisting of pancakes, butter, golden syrup and apple puree (71 g carbohydrate, 4.3 g protein, 12 g fat, 415 kcal), and 100 mL water, and containing 5g of either enterically coated pellets containing lauric acid ("CTM#3") and paracetamol (as a maker of lauric acid release) or placebo pellets. A second identical test meal (“lunch”) will be consumed 4 hours after breakfast, and will again contain 5g of either CTM#3 or placebo pellets. Those who receive CTM#3 at breakfast will also receive it at lunch, and the same for placebo.
