A very common cause of water retention Gutamin 7 in women occurs just prior to menstruation, and most always disappears as quickly as it appears. Again, this water weight gain can be reduced by drinking plenty of water, avoiding highly processed and high sodium foods, as well as maintaining an exercise program.
Another body component that can tip the scale is the amount of glycogen or carbohydrate that the body stores. The body stores carbohydrate in the liver and in muscles, in the form of glycogen. This storage is important for when one is unable to eat, such as when sleeping, or when exerting a lot of energy quickly and unexpectedly. This reserve of energy (glycogen or carbohydrate stores) weighs about one pound, and has attached with it, 3 to 4 pounds of water, hence the word "carbo-hydrate." If you fail to consume adequate carbohydrate (as many do when they begin an unhealthy fad diet), your glycogen stores will deplete, and consequently, so will the water that is with it. The body, however, cannot go for very long without adequate carbohydrate so when the body restores its reserve of carbohydrates, its associated water is also restored. Don't be alarmed by weight shifts of up to 2 pounds per day, even with no changes in your calorie intake or energy expenditure. This is quite normal and has nothing to do with fat loss. Unfortunately, the worse thing it does is create anxiety when the scale doesn't move in the desired direction.
Don't forget about the actual weight of the food you eat. If you just ate dinner and your food is undigested, you may as well just be carrying around a bunch of marbles, because the food and drink you just consumed might weigh 4 pounds. This is not fat gain. The message here is not to weigh yourself right after you have eaten because the extra weight is the weight of the food. Instead, weigh yourself first thing in the morning before you have consumed any food or drink, but, remember that the morning weight is also not representative of what we weigh either, because we are actually dehydrated first thing in the morning. The first thing we should do when we awaken is to drink water.
