I can find the make me smart option, what happened to it 

If only real life fitness were so easy to achieve.

My stomach is the bane of my fitness efforts. I'd be a size 2 if it weren't for my tummy. An entire month of (admittedly casual) exercising and it's still as flabby as ever.

Lucky sims... A few hours on the treadmill and poof!, washboard abs...

My Sims who get fat tend to be in the culinary track, or sometimes Science, because all those extra cooking points makes their food so rich.  Their kids tend to pile the weight on, too.  I've never had a Sim autonomously use an exercise machine though, unless it's a modified one, then the entire neighbourhood wants to use it.

I used to absolutely detest food, I can remember as a child wishing someone would invent a pill I could take every morning so I'd not have to eat.  I was particularly bad with meat and used to try to flush it down the toilet.  Even now I can't say that eating is at the top of my "Things I Like to Do" list, but I do enjoy Italian food.  I never realised that lack of interest in food was a Scorpio thing, but clearly it is.  As for sleeping, I put off going to bed until the very last minute, but then when I'm finally there it's almost impossible to get me out.  Luckily, I am one of those people who never put on weight, otherwise I would probably be fat as I never exercise (unless you count walking to the corner shop).

From a gameplay perspective, LTF's would essentially create "broken" sims.  Much like the yammering at the official BBS for handicapped sims or the like, such requests overlook the fact that most players will simply discard such broken sims out of hand; just look at what happens to fully functional maxian sims that just happen to be ugly.  Sims who can't experience the fullness of gameplay tend to become headstones in short order.

And if you want permanent psychological scarring for your sims, I'm afraid you're barking up the wrong tree.  I admit it's strange that fufilling a depressed sims' self-destructive wants will bolster their self esteem and return them to functional citizens in short order, but do remember that this game sells itself as escapism.  Escapist little cartoon/sitcom characters tend not to, as a rule, have deep seated issues that can't be resolved by the end of an episode.

Some kind of lot size-customising tool in the neighbourhood view would be fantastic and even more so if we could have the option to purchase/auction off land according to building needs. If we can't sell off excess land perhaps because of the portals, just the option to buy and add-on would make all the difference.
