Oh my God!

What, 5 pounds in one night? Alright, alright. I'm guessing you're female, right? It might just be bloating, water retention, etc in preparation of your period. In that case, the way to combat water retention is to drink more water. So, drink more water. As for losing weight, cut out junk food, sweets, etc. Increase your fruits and vegetables, seafood, and whole grains. Don't eat too much red meat, or cut it out entirely if you can. Also, drink plenty of water and green tea. 20 minutes of exercise daily is suggested. You may want to start lifting weights (5-8 lbs), too, since muscle increases metabolism.

hi its not unusual,as we age our BMR-basal metabolism rate ie the rate at which we burn the calories slows down and we tend to put on more weight inspite of maintaining the same life style,eating the same amount of food.so the only mantra to succesfully lose weight is to burn more calories then u take in.yes,its difficult but if you add little more activity like walking for an extra 15 minutes and cutting down on sweets,carbohyrdrates and fatty food,you will slowly but surely lose weight.

Not a problem , you can actually follow some diet and also do some exercise for atleast 20mnts of time, I am sure you are going to loose weight in shorter time.

An expert tip says: dont eat anything fit a fat percent over 3%. It might be hard, but dont eat butter ect. If youd like to take a snack eat some fruit instead. And you always do something for like 45-60 minutes a day, like ride your bike somewhere, go joggin or even just walk. It will help alot :D Anyways, just keep away from cakes and sweets, stuff like that. Good luck :P
