What are the best foods to eat to stay fit and slim. without losing my curves or shape..?

Exercise: You can't pick & choose what curves you want the body to spot reduce or keep---weight loss is global & adipose/weight redistribution is pre-programmed (e.g. "apples versus pears" body shape). You can however control calorie intake, snacking, portion & meal size, meal composition (proteins, carbs, fats). You are encouraged to exercise regularly, stay active, avoid fad diets, alcohol, & fast food.
