Placebo (140 mL isoosmotic salt water, NaCl) given 30 minutes before a liquid test meal with the addition of 70 MBq 18F-FTHA = CTR

Lactate (140 mL lactate drink = 25 g D/L-lactate bound to Na) given 30 minutes before a liquid test meal with the addition of 70 MBq 18F-FTHA = LAC The investigators will also use the 18F-FTHA standardized uptake value (SUV) to evaluate dietary fatty acid trapping and distribution, to be able to compare our results with former studies using the 18F-FTHA method.

Dynamic whole-body PET scan.
