Bad idea. Weight-loss should be gradual.
Here's a program for the period in which you want to lose weight:
Plenty of moderate aerobic exercise, no sweetened liquids at all, and no junk food at all. Preferably no sugar, and as little added salt and processed foods as possible. Eat 3 small-portioned meals/day; do not skip breakfast; and avoid sweet snacks. Limit your calories (better to consult a doctor or nutritionist concerning the amount), and weigh yourself 2-3 times/week. Ignore the sensation of hunger. If you see your weight diminishing at a safe, reasonable rate (1-2 pounds/week), keep it up.
Once you've reached your target weight, increase your calorie intake somewhat. And you can then have small amounts of sweetened foods or junk food on occasion (if at all), along with your regular foods (not instead of them). But keep checking your weight 2-3 times/week.
Avoid crash diets, diet pills etc. Avoid fatty cuts of meat. Walk as much as possible. Bicycling and swimming are good too.
More guidelines:
Don't concentrate on specific foods so much as on a balanced, healthy diet plus exercise. Plenty of moderate exercise rather than intense exercise, which can damage your joints.
Good nutrition means eating what your body needs, while ingesting as few harmful things as possible. It has also been described as getting enough of each of the major food categories (grains, fruits, vegetables, protein, dairy, etc.; plus plenty of water).
This will vary somewhat from one person to another; and I don't believe that there's any universal diet that can be prescribed for everyone. Avoid best-sellers with their perennial fad diets. And think twice before using any dietary supplements or weight-loss pills.
In general, one's starting point can be a menu of whole grains, whole-wheat bread, a good amount of vegetables, some fruits and nuts, fish, lean meats (in not-large amounts), and some dairy. However, this must be tweaked according to one's health, weight and other factors at the outset; and also adjusted over time, as one sees what works for him/her in particular.
Also...whenever you feel queasy, nauseous, constipated or otherwise not completely well, try to remember what you've eaten over the last several hours or the last day. This is one method of adjusting one's food habits.
You don't do it that quickly.
You cannot lose 50 pounds in 4 weeks by any natural means.
run fast
basically you cant !
4 weeks in a month. 12 weeks. 24 lbs
If you weighed several hundred pounds and were a boot camp contestant in the Biggest Loser TV series, you could lose 4 stone (56 pounds) in six weeks. They do that. However, they have the benefit of a qualified medical team who monitor them at all times, specialist chefs and professional trainers. They spend most of the day engaged in intensive exercise, in a state-of-the-art gym, and start the day with a 5-mile brisk hike.

Losing that much weight (as a result of dieting) in such a short time is extremely risky for your health. Losing weight should be done gradually, and preferably with advice from your doctor -- be very wary of so-called 'experts' from the weight loss product industry, as they are entirely profit oriented.
It's impossible to lose that much that quickly and it be safe. You could go on a crash diet or starve, but even then it would be difficult to do, and you would just gain the weight back as soon as you started eating normally again. The best way to lose weight and keep it off is to lose it gradually (about 1-2 pounds a week).
