Sorry to disappoint you but unless you retain water, you can not lose 20 pounds in 10 days and maintain energy. Even if you lose this amount of water, your blood
pressure will most probably sink causing weakness.
However, here are a few tricks to get rid of excessive water, fast.
1. Stop eating carbs - bread, sweets, potatoes, etc., and don't salt your
food at all!
2. Eat enough protein BUT even more "good" fats - olive oil, tree nuts
oils, fatty fish and the such;
3. Take warm or hot tub with sea salt daily.
4. Eat as much as you can stand the following: cucumbers, parsley,
watermelon, and drink diuretic herbal teas in moderation to avoid blood
pressure drops.
