Twins test out experimental diet

Fat Vs. Sugar: Which Is Worse?

It's fat vs. sugar in the battle for which is worse! Identical twin doctors Chris and Alexander Van Tulleken decided to find out ... using themselves as guinea pigs.

'Alexander could not eat carbohydrates, essentially sugar, and Chris was only allowed a little bit of fat,' 'GMA' reports.

The twins conducted the experiment for an upcoming television program on BBC's 'Horizon.'

The diet lasted for one month. Besides their restrictions, the self-proclaimed gluttons were allowed to eat as much as they wanted and exercise the same amount as usual. So, what happened?

'Both lost weight, but were miserable in the process.'

Alexander wrote about his experience for Daily Mail. He shared that on the no-carb diet he was slow, tired and had terrible breath. He said Chris, on the low-fat diet, was never full and always snacking. Alexander concluded they were going about it all wrong, saying:

'If you want to lose weight it will be much easier if you avoid processed foods made with sugar and fat. These foods affect your brain in a completely different way from natural foods and it's hard for anyone to resist eating too much.'

'Good Morning America' brought on its Chief Medical and Fitness editor who chimed in with a few more tips.

'There's three things you need to do: You need to eat less, you need to eat differently, and you need to use your body more.'

Noted! The twins' special will air Wednesday, January 29th.

I would like to know if anyone at aol monitors these comments. I would think their experiment with making you use FB or Twitter would make them see that they are ignoring many people. Apparently they do not care.

I have no use for Facebook. HP is just racist / discriminating against those who don't use Facebook.

Unfortunately irresponsible capitalism has obliterated our food supply. A burger from Mcdonalds, or a coke, or a can of soup 35 years ago is completely different than what you find today. The quality of todays food is poor. Too many unnatural things added that can't be processed and have not been studied for long-term health (AND mental) effects. Besides you're 80 and you have 1 foot in the grave. You should be eating whatever you want.

Sugar (processed sugar) is the enemy. The body NEEDS fat so support proper function along with good hydration. Balanced diet with exercise ( any activity even just walking) will yeld results.

NO the enemy is EXCESS in any form. EXCESS sugar, EXCESS fat, EXCESS inactivity, EXCESS processed foods. If you take these things in the moderation that is acceptable, and exercise adequately, get enough sleep, and otherwise take care of yourself, eat sufficient vegetables and whole grains and low or non-fat dairy and so forth, remembering that BALANCE--not any EXTREME, will win the day for you, you'll be fine.

Any idiot can say that some one thing is bad and act as if striking that one thing will fix it all. It NEVER works. Taking care of yourself and being sensible DOES. A simple search of reputable health sites will tell you this. I'm not telling anyone anything they didn't already know they just want an answer that says "you can cut out this ONE thing and you'll drop the pounds without changing your life" well that's not going to work. Sugar is Sugar is Sugar. Sugar from a banana has the same amount of calories that you must burn to prevent it from turning into FAT as the sugar from sugar cane that we process into white sugar and put into a piece of candy. Period. end of sentence. end of paragraph. end of rant.

I do not like the way aol handles their site. The double posting is annoying. I also do not like that aol has HP articles that are not accessible to people w/o Facebook accounts. I used to like reading/commenting until they added that stipulation. Now I do not bother b/c I know they do not value my opinions. I do not need to support them.
