newby guy….ready to chime in on the water thing.
drink water. plenty of water. my wife had some depression issues at one time. her water intake ( and fluids in general) was way to low. she started to beat depression by walking a mile a day on her lunch break and drinking at least 1/2-1 gallon of water a day…what a difference!.
i noticed a lot of good things as well when i stopped drinking so much beer ( almost a six pack a day) cut my caffiene pop intake and got heavier on water/black tea/and diluted gatorade. i lost beer weight (hops contain some plant estrogens, thus ‘mantitties’ and stuff) and had some more energy.
the other part for losing weight is to do the models trick of drinking ice water. your body has to burn calories to warm the water to a usable temp in the body. just remember not to cool off to quick when you are working out. keep beverages about room temp or a tad cooler when your body temp is high from exercise.
