We now know which cycling intensities are best for fat and calorie burning, but what about the other question: should cyclists really ingest fat as they exercise? Even more importantly, it doesn’t give you any information on where that body fat is stored. It’s possible that some ingested fat could be absorbed from the digestive system and carried to the muscles during 85%-V02max efforts, but blood flow to the small intestine is rather meagre during such high-intensity efforts, so absorption rates could be low.
