Get rid of baby fat on your lower abs by adding 30 minutes of cardio to your lifestyle at least three times a week; this will help reduce stress, too.
Babies have the most, being born at about 78%. By one year of age, that amount drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water. Thus: 1  Babies and kids have more water (as a percentage) than adults. 2  Women have less water than men (as a percentage).
This healthy body water percentage chart will help you determine if you have enough water in your system. Many scales will tell you this value in seconds. Because your fat in your body has a lot of water in it, you have to first know how much fat you have in your body before you can then figure out what your healthy water content is. That is, if you say have 33% fat in your body, then you only need another 37% of water alone, because you have water in the fat. The scales don't count fat water as water, otherwise your numbers would get very confusing :)
