Can you lose weight without drinking water for 48 hours?

Yes, but you'll just dehydrate yourself. It would be better to drink water and eat very little for 48 hours to lose some weight.

There are no miracle pills or hi-tech machines that cause a person to lose weight. There are no shortcuts or magic spells that will make pounds disappear. Weight lossis something that is achieved through some regular changes in eating habits and a bit of regular exercise. Do not be fooled into thinking anything else will work. It will not (despite the claims of the weight loss industry - a multi $billion enterprise).

Read up on nutrition, start making some permanent changes in your eating habits, and do something on a regular basis to put your body through its paces and get it to work with you to shed weight.

Enlist anyone to enter the process with you and "buddy up" to make things happen. Family and friends need to be informed of your intent and asked to help. Family help is critical if you eat at home with them. You'll need more of the "lighter" stuff and less of the "heavier" stuff on your plate. Get your "posse" together and go for it. The change comes between your ears first, and the rest of your body follows along as your "command center" dictates.
