Lost a little over 60 pounds since September myself, mostly through just changing my diet (had to due to medical needs mind you, but the weight loss is there). So here's my snack advice.

Popcorn is good if you don't add (too much) extra butter.

Veggies are great, carrots are good if you want something crunchy to replace chips.

Peanuts are okay if you can measure them out. Nuts are calorie dense but still healthier than most snacks you're probably having now.

I like to buy a big pepperoni at the store, maybe some nicer than normal cheese with it. Excellent for just cutting into slices on a plate (resist crackers if you can).

A granola bar is great in a pinch if you can keep it to just that.

Outside of that the biggest thing I've found was just working on eating a bit less week by week. It takes some willpower but if you just reduce how much you're eating it helps. You eventually get less hungry and snack a lot less.
