Everyone here talking calories and forgetting water weight. Boxers etc. will drop carbs entirely to make a weight cut-off. Two aspects to consider here, glycogen and inflammation, both of which store water. If you are not fat adapted and stop carbs your glycogen will deplete (~500g glycogen + 4x that in water, 2.5kg = 5+lbs), also called hitting the wall in endurance sports.
If you have systemic inflammation your fat cells will carry a bunch of extra water (you know when your ankle swells up after twisting, that’s water from inflammation), so removing inflammatory stimuli, foods, environment can cause that to get peed out. Depending how many fat cells, the amount will vary, but could easily be 5kg if obese.
This is how people lose dramatic amounts of weight in the first few weeks of diet. Actually removing fat is a lot harder, but it starts in the kitchen.
