Where did you get 30g of carbs from for the pre- and post workout?
Given that the total calories are the same, differences in carb and fat macros will not matter. It it is the calorie deficit that creates weight loss, not a lack of fat or carbs, and high enough protein intake will ensure you don't lose too much muscle mass.
That said, carbs are best is best stored as glycogen (basically energy for the next session) in the few hours after a training session, so they carbs are most efficiently used/stored at that point. Other than that, the amount of carbs you need should be reflected in how hard you train and how much carbs you need to perform well. Some people thrive on low carb/higher fat and some want the opposite. That is individual.
But if you have few calories to play with and you want to have a decent amount of carbs every day, it would be smart to have them around the training session. The meals around training should ideally also be lower fat to not delay the nutrient uptake. If you have a immediate post workout shake it "should" be close to zero fat. However, it will work just as fine to eat a meal if you do it within two hours after the session.
