So you drink quite a bit of beer and you've also got a fat gut and you guess that it's a 'beer belly'? You may well be right. - But here is some information you may not know about, that I've cut and pasted from this webpage:
Sodium retention can lead to a further problem called ascites, an abnormal accumulation of fluid in the abdomen, which partly accounts for the protruding abdomen of steroid victims. The good news is that when salt/sodium intake is lowered, the ascites will be reduced along with the fluid retention in the blood vessels. Cutting down on alcohol also reduces the fluid in the abdomen.
You may well conclude from that, and I would agree with you if you did so conclude, that it is really more the fault of sodium retention/salt sensitivity/fluid retention that you are the possessor of that 'beer belly', even though you are probably not a steroid victim. - Whether you cut down on salt or cut down on alcohol, cutting down on either will reduce that fat abdomen, and I suspect that intentionally cutting down on salt will have a more noticeable effect than intentionally cutting down on alcohol, because when you reduce salt intake, one of the benefits is that your thirst is reduced, and so without much effort you may find yourself drinking less beer. - Two birds with one stone! - Well done!
Lose weight by eating less salt! -Go on! - Try it! - You will feel so much better!
