Is there anything linking sleeping after breakfast to weight gain?

a few days ago in the morning, i woke up at 6 like i normally do for school, ate breakfast, and then found that i was ill so i stayed home. I went straight to bed. I’ve been sort of ill and have had to energy, so i havent been exercising during the day. Is there any proof that this can cause weight gain? or is it different because it boosts your metabolism? I ask because i have done this several times and i like to do it because if i need to sleep in, i dont like eating brunch at 10–12 because then my eating schedule is all screwed up. What if i got up, ate, and then waited an hour or so before going back to bed? I’d like some professional advice/info/proof if anyone has any.
Thanks.
