Weights, and pretty heavy ones, are useful in strength training. Even if you were to haul around a heavy backpack, your caloric burn would not increase by much. Instead, you might end up having back pain for carrying a significantly heavy weight for too long. Carrying weights while walking/running is not a good idea in the hopes of burning more calories. There are far more efficient and healthy ways of increasing the caloric burn, such as running, fast walking, biking, etc.
