There is this quotes that says “The thought of no being where you want to be should be enough motivation” if this helps. Also their are fun ways to exercise like riding a bike. Walking a dog, swimming and heaps more.
But something that can help is probably before u eat drink water because thy say if you drink water before u eat it will fill u up and make u eat less. Or maybe since the summer is coming up u can walk places or run down the block a couple times.
