I am sorry to say it but, there is no safe way for quick weight loss. Face the facts, it took you months or even years to put on all of that weight. It will take just as long to take it off again. You cannot rush your body. Companies make millions of dollars trying to convince you that you can lose 20-30 pounds in 6 weeks or less, don't you believe it.
Losing weight is NOT an overnight quick fix. You cannot expect to get in that bikini for the summer if you have 60+ pounds to lose in 4 months. Losing that much weight in that short of a time puts your major organs at risk.
Take you weight loss at a slow but steady pace and learn not to put it back on and you will be well on your way to a healthier you.
