It is feasible to lose weight quickly but you should be realistic and understand that if you lose weight fast then you will almost certainly put it all back on again just as fast. The one diet that really worked for me is wu-yi tea, it can be viewed in the resource box below, they have a few free trials in stock, it was reported in Fox News and CNN. I lost thrity pounds, it really does produce success!
Exercise! HIIT is the most effective form of cardio of burning fat. See http://fit-muscle.blogspot.com/2009/01/get-hiit-fit.html for my article about it. Speeds up your metabolism and burns loads of calories.
EAT ONLY NATURAL FOODS LIKE FRUIT, VEGETABLES, EGG WHITES, SALMON, FISH, CHICKEN, AND WHEAT BREAD. SPLIT YOUR MEALS UP THROUGHOUT THE DAY. ALSO EXCERSISE 45 MINUTES EVERYDAY. IF YOU DO THIS I GARUNTEE YOU WILL LOSE WEIGHT
