so you want to lose 22 lbs in about 6 weeks? for you to be healthy it probably won't happen, but you could lose about 16 lbs so you'd be down at 114 lbs. 130 is healthy at your height. Don't be skinny because other people are, I'm losing weight because I want to be healthy again. Try to eat healthier foods, cut out junk food etc., and eat more fruits and vegetables and lean proteins and work out/ exercise 3 times a week. You should lose the weight no problem.
