The compound of claim 1 comprising 15 to 30 nucleobases in length. 3. The compound of claim 1 having at least 99% complementarity with said target segment. 4. A method of lessening the severity of a condition of an animal, wherein the condition is obesity, diabetes, cholesterolemia, or liver steatosis, comprising contacting said animal with an effective amount of the compound of claim 1 thereby lessening the severity of said condition. 5. The method of claim 4 wherein the obesity is diet-induced. 6. The method of claim 4 wherein physical indicia of obesity is increased fat. 7. The method of claim 4 wherein the animal is a mammal. 8. The method of claim 4, wherein the liver steatosis is steatohepatitis, non-alcoholic fatty liver disease or non-alcoholic steatohepatitis (NASH). 9. The compound of claim 1 having at least 100% complementarity with said target segment. 10. The compound of claim 1 comprising an oligonucleotide. 11. The compound of claim 10 comprising an antisense oligonucleotide. 12. The compound of claim 10 comprising a DNA oligonucleotide. 13. The compound of claim 10 comprising a RNA oligonucleotide. 14. The compound of claim 10 comprising a chimeric oligonucleotide. 15. The compound of claim 10 wherein at least a portion of said compound hybridizes with RNA to form an oligonucleotide-RNA duplex. 16. The compound of claim 1 having at least one modified internucleoside linkage, sugar moiety, or nucleobase. 17. The compound of claim 1 having at least one 2'-O-methoxyethyl sugar moiety. 18. The compound of claim 1 having at least one phosphorothioate internucleoside linkage. 19. The compound of claim 1 having at least one 5-methylcytosine. 20. A kit or assay device comprising the compound of claim 1. 21. The compound of claim 1, wherein said compound is 20 nucleobases in length. 22. The compound of claim 1, wherein said compound is an antisense oligonucleotide comprising: a gap segment consisting of linked deoxynucleosides; a 5' wing segment consisting of linked nucleosides; a 3' wing segment consisting of linked nucleosides; wherein the gap segment is positioned between the 5' wing segment and the 3' wing segment and wherein each nucleoside of each wing segment comprises a modified sugar. 23. The compound of claim 22, wherein the antisense oligonucleotide comprises: a gap segment consisting of ten linked deoxynucleosides; a 5' wing segment consisting of five linked nucleosides; a 3' wing segment consisting of five linked nucleosides; wherein the gap segment is positioned between the 5' wing segment and the 3' wing segment, wherein each nucleoside of each wing segment comprises a 2'-O-methoxyethyl sugar; and wherein each internucleoside linkage is a phosphorothioate linkage. 24. A method of lowering DGAT-2 expression in a cell or tissue of an animal comprising administering to said animal the compound of claim 1, thereby lowering the expression of DGAT-2 in said cell or tissue.
