This is not necessarily the only option... For example, if the frog was kept cool enough it may not have even lost a significant amount of body weight.
And if there is a gastrional impaction, force feeding the frog could very well be one of the worst possible options as increasing the mass in the digestive tract can cause significant damage to the digestive tract... This can result in death of the frog.
The frog should be examined by a vet to determine if there is an impaction or other problem.
In addition if the frog has lost significant amounts of weight, force feeding has to be dealt with very carefully as a significantly large meal can cause death through refeeding syndrome. The meal should consist of no more than 50% of the kcals the frog needs to sustain basal metabolic rate..
If you do have to force feed I would suggest tube feeding the frog with feline clinicare (obtainable from your vet).
