I'm telling you, it was just crazy fast. And - Stedman lost the couple of "ounces" that he gained whereas I was NEVER able to get Tatum to lose an OUNCE of what she gained on the food. | 
 
  OH! And I also meant to tell you that the vets I've talked to have also said that allergy tests are expensive and largely unreliable bc, like 
you said, you end up with a list a mile long, so where does it get you? Back to square one, like you were thinking

Yeah, I don't get this weight gain. It almost sounds similar to what they're now learning with some humans - that there are indeed some humans who, despite *not* overeating, they cannot lose weight. And it has to do with leptin and blah blah. Not that this may have anything to do with Tatum - but my point is, there are so many reasons she could be holding weight - some of which we don't even have the answers to yet. So, I do think you're on to something here, even if it isn't the thyroid.
