This is a serious question??
The answer is No. Serious answer.
How many single parent children do you think are out there??
There is a LACK of Education...with the question as well as the realities in the US. Portion sizes since the turn of the 19th century have grown exponentially (meaning over and over and over), the actual size of the food has as well. Being educated on the need for physical activity and healthy menus should curb obesity. However, it needs to be GOVERNMENT Sanctioned. Meaning, the government needs to step in with legislation prohibiting supersized portions. People should be able to live by the motto"Everything in moderation"but we don't. Individuals need help with this. Thus why it should be the government to govern this.
For instance the USA pushes Denny's and IHOP and all those buffet styled restaurants so hard that parents (single or not) who are not making much money (which is quite a few families when you look at the poverty level in the US) have little choice when it comes to 'treating your family".
My folks went to Florida in 2001. They ended up at Denny's 3 times in 8 days. Did they over eat. No. They were responsible with what they ate. However, sitting next to them was a family (mom,dad and son).The son was less then 3 yrs old. The mom went and piled 3 plates,all equally filled, and placed them in front of the three of them. The little boy could not fit in a high chair,nor did his clothing allow for much movement. He was expected to finish his plate like his parents had. The Mother berated (yelled and screamed) at this child because he would be wasting their money if he didn't finish his plate??? Child abuse?Neglect?
The perception of what is cheap is good needs to go out the window. Food producers need to make raw product more accessible and affordable. Again an area where the government could come in.And there needs to be more education for parents and children about the negative impacts of over eating,not exercising, and only eating take out.
But to seriously blame a single mom for All the Obesity in the US....that's just ridiculous.
