The only important carbon part is the carbon used in transporting and growing the food in the form of fuel. We’re not releasing trapped carbon when we’re eating food as the only way we would save carbon in that situation is if we grew the food and buried it. Worrying about raw energy efficiency gets nonsensical because soon you’ll be factoring in the solar energy conversion efficiency between growing and eating plants vs growing and burying plants to turn them into oil.
The better point is just that a bicycle is an incredibly efficient machine for moving a person in terms of energy input to work done compared to the hunks of metal cars are.
Well the meat industry is a large source of emissions isn’t it? So if our meat consumption increased due to increased caloric intake, that should have a carbon impact right?

Sure but if you’re using anything but carbs and fats to power exercise you’re doing it wrong.
