How to reduce weight faster?

The only way to safely "speed up" weightloss is by doing exercise alongside your weightloss diet. Cardiovascular exercise (walking, running, cycling, swimming) is usually best since it does not encourage huge amounts of muscle gain.

If you really want to lose weight quickly, try a camping holiday in a location with lots of walking opportunities. The combination of slightly unappealing "camping food" and lots of walking results in quick weight loss.

Alternatively you may experience a few pounds of water-loss just from cutting salt from your diet. (Although this is a temporary measure since it will be regained when salt is consumed).
