Description
Inclusion Criteria:
- Men and women ≥65 years old;

Experimental: Triheptanoin
Participant will undergo POST Triheptanoin suppementation 1g/kg body weight for 28 days (dose gradually increased each week, starting at, 0.25, 0.5, 0.75 and then 1 g) separated in 4 doses (with eah meal and before night) after a control PRE supplementation imaging protocol.
|
The target daily dose of triheptanoin will be 1 g/kg/d, or approximately 70 g/d during 28±2 days.
It will be divided into four daily doses, one of which will be consumed at each meal and one with an evening snack.
