That is the reason I'm on a diet :-)
One diet is to eat 90% fat. A sutdy showed that participants all lost weight even though they ate the calorific amount required for sustaining. I remember tho that participant said how hard it was to eat just fat, and wondered on why you would do this study (I think it was UCL did this work, might be wrong). I see now that conditions like epilepsy can under certain conditions be aided by very high fat diets or ketogenic I think they call them.
So I guess we need the knowledge and often taking extremes shows us new ways of understanding our bodies.

It's more like eating the right foods FOR YOU as an individual. I have learned from long personal experience that limiting carbs works far better for me than only limiting calories. Limiting both - but not severely limiting calories - works best for with me when trying to lose weight.
We all know thin people who can snack on sugary stuff and doughnuts and burgers and not gain weight. They seem just fine. I can guarantee however that I would definitely gain weight on a sugary diet, in fact it has been a real problem for me since childhood. I cannot tolerate large amounts of sugar or other carbs and even hope to remain slim. That's just a fact so I work around it to maintain. And sugars in particular make me very very hungry and perpetuate my worst cravings.
This doc is obviously not like me - therefore this high sugar high starch hi junk diet worked for him. But of course a mere two months is nothing. Were he to eat like that for lifetime or even a year I bet the malnutrition symptoms would be obvious.

For me sugar is most definitely the 'baddie'! If I eat sugary foods I begin to crave more, and chocolate, sweets, biscuits and cakes, if taken in only small amounts, set up cravings I very often cannot resist.
A lot of people find that they binge when low carbing, perhaps because they are not in proper ketosis, or perhaps because, once they have given in and had a few carby things, their cravings are back in force. This is why it is important to fight the urge to eat sugary stuff. It takes low carbers out of ketosis and lands them right back where they started!
Having said that, diets such as Atkins are very forgiving. Ketosis is always there, waiting for us, when we decide to come back.
Wish I'd not read that! I'm at work and went for coffee and the conversation turned to unhealthy food, all we spoke about for 15 minutes was fast food and deep fried mars bars. Anyway, great to know I'm off to the gym at 730pm tonight and eaten healthy food all day
Surely we all know by now less calories in than out = weight loss?
They say the camera adds 10lbs - Just how many cameras do I have on me?

Don't understand why he needed to do a demo of what we all know already, has this not been proven a million times already. Just the reason we eat healthier is we can have more food for our calorie count to keep us satisfied for longer! Surely this doctor must have some will power, that should have been his test....to see how little rubbish he could eat and control the craving lol. Less calories in, more calories out = weight loss x
Life is Precious
I have a friend who eats like this, she's on medication that gives her no appetite and so she just picks at junk food. She's lost weight because of it (but she didn't intend to) but I bet you'd feel horrible subsiding on sugar D:

Its like all those people you see on supersize vs superskinny... The skinnies nearly ALL snack on chocolate bars/coke/crisps, but they eat nothing else.
You can lose weight on a chocolate only diet, but you'd only be eating 3-4 mars bars a day.. maybe? Thats not a lot of food compared to a conventional diet!! I dread to think how he felt after a week of that... and his insides were probably screaming, and sending him on a very fast track to diabetes!
I suppose the point is that you need to eat LESS to lose weight. Even diets with "free" foods have to be taken in moderation. Thats the theory - even if its pointed out in a somewhat obnoxious/patronising way.

I guess it all depends on the person...some people this diet will work others it wont
no way i could do this diet
