My nine-year-old dog was getting pretty fat, eventhough I was walking him him every day. Logic told me that if I fed him less, eventually he'd weigh less.
I couldn't figure out why that wasn't working until my daughter made the observation that he wouldn't lose weight until he started eating better. She said the chow he was eating was comprised of more fat than nutrients, and until I purchased a higher quality dog food, nothing was going to change.
It hit me that for all I have to say about eating well, I had failed to apply that knowledge to what I fed my dog.
So I invested in a better brand of dog food, kept up the exercise, and in a little over a week I noticed he looked a little bit slimmer.
Of course, it's no different for anyone who wants to drop some weight. Start eating more nutrient-packed foods and your body will begin to reshape itself by dropping excess weight.
You don't save a thing by buying cheap food, for yourself, or for your pets. What you don't invest in quality food will end up getting spent on visits to the doctor or to the veterinarian!
