Shifting from IF to two meals per day, negative effect?

Well, I am currently doing IF and my eating windows is from 9 till 17. I however going to start school soon and I don't really like eating at school both due to time and the fact that I would have to carry extra weight, plus when I eat there, even if in decent quantity, I am always hungry. Last year I used to eat between 7 till 8 and then again between 17 and 18 and I think I am going to do the same. Start school at 9 till 16.30 and it takes time to comes homes. Except some drop in my metabolism, which other thing would change. P.s: I tried in the past to either have 2 meals after school, or one before sleeping and one after waking up, but I think it is worse both in term of energy and hunger via /r/intermittentfasting https://ift.tt/2PNNIdn https://ift.tt/eA8V8J
