I could not disagree with that statement more. Weight loss does not have to be torture. It is not something to "get through."
Long term weight loss is a lifestyle change and a lifestyle that can be fun and rewarding. Look at all of the Biggest Losers that have mentioned being able to hang out with family members, for example.
Am I to assume that they are "persevering" their family members?
Don't get me wrong, the road to dramatic weight loss is frought with challenges, but those challenges are something to be embraced. The lyrics to the theme song of this show is "What have you done today to make you feel proud."
The challenges you face as you burn fat are there to make you feel proud, and not simply to persevere.
