Cast:
Create a sim with the largest possible body shape (both sliders at full)
Have the sim have the glutton and lazy traits
Give them the Bodybuilder Aspiration

Setting
Move them into any house or build your own. Do not cheat to get money!

Goal
Get to level 10 of the fitness skill however possible (no cheating)
Have them finish the bodybuilder aspiration
Have them reach the highest level of either athletic job branch

IT IS VERY IMPORTANT THAT YOU DON'T CHEAT OTHERWISE IT DEFEATS THE PURPOSE

Oh, that seems funny! I will try it.

This sound like one of those quick, fun challenges I like. I'm going to put it on my to do list.
I do have a question though. Why would you put the muscle slider all the way up if you are
making an obese sim? A sim who never works out should not have any muscle.

This challenge seems like a fun idea, and I've decided to create a blog on it! Here is the link, please show your support and check it out! - simsbeatobesitychallenge.blogspot.co.uk

The reason is because to get the max body size you need to have the muscle slider at full it is does not actually give them muscles

So I created Mucki Meatloaf, a huge, big... wide man, lazy and always hungry.
He's always so exhausted when I sent him jogging or to the fitness-center.
He likes flirting with curvy women :lovestruc and watching comedy on TV.
It is hard to get him motivated to go to his athletic work...

This challenge is fun, because it has not so many restrictions like the fitness-challenge, I think it is rather different, no offense meant.

no offense taken, but that is what a challenge is,if you think about it.

Lazy gamers like me prefer lazy challenges.
To me fun is more important than difficulties, but that's only my personal opinion.

Your link does not work and typing it in doesn't work either. I'd like to look at it, where is it please?

I'm in the middle of this one right now. I originally made him a bro on top of the glutton and lazy characteristics, but then changed him to be a slob instead of a bro. I figured it would be more realistic seeing as lazy and slob tend to go together. Where I'm conflicted is whether to spend his satisfaction points or not.

lol I'll have to make myself and see if I can do it haha

Finally typed in sims beat obesity and found the blog has been deleted.

I'm doing the Beat Obesity Challenge as part of the Clone Challenge. Meaning one of my clones will be doing this challenge. I added one thing to the challenge for myself though. She has to get to the top of the athletic career. Here's my blog post: Clone/Beat Obesity Here's the intro page for the Clone Challenge: Clone Challenge
