In the throes of premenstrual cravings and bloating, weight loss can seem especially elusive. However, the onset of your period does not have to prevent you from shedding unwanted pounds. As with any other time of the month, you'll lose fat by burning more calories than you eat throughout the day. If premenstrual syndrome, or PMS, brings food cravings, force yourself to wait 10 minutes before reaching for that brownie. If you still can't resist, have just a small piece instead of the entire square.
Lose the Water
Before your period, you may gain fluid weight as your body retains water. You can help lose this water weight by reducing salt consumption and engaging in exercise, according to Medical News Today. Drinking plenty of water can also help, because a well-hydrated body is less likely to store extra water.
Shed the Fat
To lose 1 pound of body fat, you must consume about 3,500 fewer calories a week than you burn through physical activity. Using this as a guide, create a 500-calorie daily deficit to lose 1 pound per week. For example, eat 250 fewer calories than you typically need for weight maintenance, and burn 250 extra calories on the treadmill. Some women are prone to food cravings before their periods, according to the Office on Women's Health, so you may need a bit more discipline than at other times of the month. It may help to keep a food diary and write down what you eat and drink for each meal and snack to keep track.
