How can i lose weight without hanging skin?

Lose weight slowly: Lose weight slowly, exercise regularly, muscle strengthening exercises and resistance training to build mucle tone, moisturize daily and before bed, stomach crunches, drink lots of water, healthy diet rich in vitamins and minerals, exfoliate the skin, avoid drastic measures such as gastric bypass (which causes sudden drastic weight loss which always results in hanging skin).

May not be possible: The problem of redundant or hanging skin after weight loss is more likely with large amounts of weight loss. The younger you are the more likely you are to have your skin "tighten up" after weight loss. Options for dealing with sagging skin are surgery & non-surgical tightening procedures which work through heating the deep layers of the skin (many without downtime or discomfort.).
