Spark calorie suggestions are usually on the high side. If I ate what they recommended, I would gain weight rapidly. But this is do to a very slow damaged metabolism from a lifetime of yo-yo dieting. If you are losing weight steadily, then that should be the correct amount. If not, maybe remove 100-300 calories a day from your meal plan to see if the scale starts moving down again. I always have to play around with my calories to get the scale to move or maintain.
