It doesn't. Fats get broken down into glycerol and free fatty acids. These are then converted into acetyl-CoA (glycerol the same way as sugars; fatty acids by beta-oxidation). The acetyl-CoA then enteres the krebs cycle.

just to add on
keep the following in mind
fats can join in at the link reaction...
this will not result in their conversion to glucose but can act as a glucose substitute to give energy

Fat(TG) broken down to glycerol and three molecules of fatty acid.Glycerol has no fate in adipose tissue .It goes to liver and by gluconeogenesis converted into glucose.

odd chain fatty acids are converted to acetyl CoA and last three carbons as propionyl CoA.propionyl CoA is converted to succinyl CoA ,an intermediate of TCA cycle. All the intermediates of TCA cycle are glucogenic.

Tg are converted to 3 molecules of fatty acids and glycerol. Glycerol goes to liver ,get converted to Gly-3-PO4,then to dihydroxy acetone phosphate-- ---Isomerase----------Glyceraldehyde-3-PO4
dihydroxy acetone phosphate + Glyceraldehyde-3-PO4=Fructose-1-6-bisphosphate---Fructose6-phosphate------G-6-P-----Glucose
