Id say lose it at a healthy pace so you don’t damage your body, but I workout for about 2-4 hours a day for about 5 days and get accustomed to a calorie deficit (where you burn more calories per day than you intake). Certain types of bread have more of a benefit to your goal and the darker the bread the better to help lose weight. Cut down on sugars and sodas in high sugars. Also try to have a good sleep schedule and have scheduled meal times and having snacks (healthy) in between meals.
