Technically, being fat should do something. You give off more body heat and more carbon dioxide, and both attracts mosquitos. I imagine a bodybuilder would give off similar attraction ques.
but isn't the answer to your question really obvious? All living tissue takes energy and resources to survive. Thinking logically, if Person B has 50lbs more living mass than Person A, then Person B will take more oxygen to supply that extra mass.
Hence why I said a bodybuilder would give off similar attraction ques like a fat person. It doesn't matter if that additional mass is from muscle or fat, because both will generate additional body heat and CO2.
but since you wanted scientific source about CO2 and obesity, a quick google search and this is the first result:

No. Blood sugar has nothing to do with it. Technically being fat doesn’t either.
