I have lost no weight this week, despite a 7k+ calorie deficit and a further 7 days of exercise. This could be water retention or I may have lost fat and gained muscle. The scientific method of looking at myself in the mirror makes me feel happy with progress despite what the scales are saying.
You build muscle incredibly slowly, but if your exercise regime has increased your glycogen stores in your muscles may well have gone up which will increase water retention (3g of water is retained per g of glycogen IIRC).
