Talking about changing lifestyle. My friend is so busy at work that she really hurries home to relax after office hours. She would watch tv for hours and eat the whole time. Then later she noticed that she has gained weight. She realized she has to change her habits if she wanted her figure back. Luckily there was a gym in her office building so she didn't have to go far. She enrolled herself and religiously went there every other day. She no longer buys junk food. Instead she ate fruits when she feels she needs a snack. She was also careful about the food she ate. She regained her usual weight and now even got more confidence in herself.
