I can't really say I've ever been fat or overweight in my life. However, I have had up until recently a small spare tire.
I would like to let anyone who is overweight or who just wants to drop a few pounds in on some advice. I now pretty much have my abs back.
The way that I did it, and it will/should work for everyone else as well...stop drinking soda. The sugar in soda is a huge cause for weight gain and such.
A few very good alternatives are the little drink mixes that are now available. While there is a huge variety, I'm partial to the Arizona tea and lemonade mixes.
Like this one:
You can also get several flavors of the Gatorade Propel fitness water mixes like this too. They are generally about $3 for a pack of ten mixes.
I know Crystal Light has flavors of these types of mixes as well as Hawaiian Punch and such.
That said, if you do decide to try this route, be sure to check the ingredients and ensure that it contains Sucralose, NOT aspartame. Aspartame is known to cause cancer. Steer clear of ones that contain it.
Not only will you cut back immensely on sugar, these are quite a bit less expensive than sodas. You're not going to buy 10, 16-20oz sodas or Gatorade for $3.
