What are some healthy snacks i can eat to replace chips? something i can eat and it won't make me hungry for more?

Try nuts,esp.almonds: Research shows those who eat almonds instead of other snacks lose significantly more weight. Chips are mostly carbs and unhealthy fats, whereas almonds contain protein and healthy fats.Ultimately they're more satisfying and filling.Other nuts like pecans and walnuts have similar benefits. Ideally get organic nuts.See http://tinyurl.com/jyp7w89 You can also snack on low-glycemic fruits like apples.

Fruit.: Fruit is low in calories, high in nutritive value and often contains some fiber. The down side of your strategy is that there's no room to include some protein, which is important. Perhaps a little bit of yogurt with your fruit? I'd rather see you invest some more calories and include protein with your carbohydrates.
