Is it possible that the appetite-suppressing effects of coffee are at play here? I’ve read about the general health benefits of reducing calories and I wonder how big a factor that is in caffeine/coffee studies.
For many people including me, coffee consumption throughout the day reduces the appetite a lot. Two cups of coffee and my food consumption might be 25 per cent lower.
That said, this effect may be balanced out by all the people who just must have a cake with their coffee and who sweeten their coffee with sugar.
Also, none of the booze lovers I know drink coffee much. As if the beverages were somehow incompatible. This will show on the liver side as well.
That said, when they do coke, they do at least half chalk. Pure cocaine is not easy to buy on the other side of the Atlantic.
