Do you have any tips to help me lose weight?

hey i’m 16 and i’ve recently gone from 8 st 8ish to 8 st 5 in two days. Anyone have any other tips to share with me? I want to get down to the 7’s. I eat healthy at the moment. I skip lunch and breakfast and eat as little as i can bare until I eat my tea at about half five in the evening. Thanks guys.
