Make an exercise routine:
First of all, you will have to lose the extra weight you have gained. There is no doubt that you will have to sweat hard to burn your body fat but you can get the maximum with minimum effort by following a proper exercise routine. Get up early, spare some time for a morning walk and then do exercise at least for 30 minutes. You may seek help from a professional fitness instructor but if you can afford that then there are few set of exercises which you can follow without any supervision. Do push-ups, pull-ups, squats, sit-ups, V-ups, yoga, aerobics etc.
Make useful hobbies/activities:
If you do not have any hobbies or activities then think of something that can be helpful in losing some body fat as well. Consider dance training, cycling, swimming because these activities are as good as any exercise. Be regular and you will see the magic prevailing.
Plan your meals:
The next thing you will do is to adjust your meals. You must eat wisely and stay away from unhealthy items especially junk food. You can replace sweets and chocolates with fruits and different salads. You do not need to starve to get a flat tummy but you should increase the intake of vegetables, beans, nuts etc. Moreover, you should eat smaller meals during the day and avoid eating frequently. Use low-fat products and look for the valid replacements.
Drink plenty of water:
Drinking plenty of water during the day will not only keep you hydrated but it will also keep your stomach filled. Ultimately, you will not be eating over and again. You can also use lemon water as it will increase your metabolic rate and help in cleansing your body.
Get enough sleep:
You must sleep six to eight hours daily because sleeplessness slows your metabolism.
