First, you are probably wondering what this has to do with eating on the cheap. That is easy. When you are well hydrated, you eat less. If you eat less, it costs you less. Also, when you lose weight, you will be less hungry – thus saving money. So, without further delay, how do you lose weight with water?
It is important to note that you can lose tons of weight simply drinking water. People are surprised when they hear this! Generally they don't know that their body is retaining water due to their lack of water consumption. You see, we are built for survival. If you don't drink enough, your body will retain water for “just in case”. With this in mind you can see how water can actually help you lose weight!
You don't have to drink plain water. However, avoid sugar and caffeine as these can be counter-productive. You may want to consider drinking green tea as it possesses some extremely healthy effects (including evidence that it can aid in weight loss). If you combine green tea with increased water consumption, you just may be amazed at how well your weight loss begins to progress.
Also, remember to lower your sodium consumption as this will dehydrate you and cause you to retain more fluids (as well as do other damage to your health).
