  • Less Calories Equals Better Memory



    Eating less may make you slimmer but researchers are saying it will also improve your memory.


    Two for the price of one – cool.

    This is the first study that links improved memory to calorie reduction.  Researchers studied 50 men and women ages 50 to 72 ranging from normal weight to overweight.

    Dr. Agnes Flöel of the University of Münster in Germany, a neurologist, conducted the three month study.

    One group ate a normal diet but cut calories by 30 percent by eating smaller portions.  The second group increased the unsaturated fat they ate by 20 percent. A third group made no dietary changes.

    After three months, they took tests which involved the memorization of words. The calorie-restricted group showed a 20 percent improvement in memory performance. The other two groups showed no change.

    Cutting inflammation

    Dr. Flöel said memory improvement could be linked to a decrease in insulin and inflammation in the calorie-restricted participants, who lost four to seven pounds.

    According to Dr. Flöel, lower insulin levels may increase the sensitivity of receptors in the brain and improve insulin signaling, which allows memories to be maintained longer.

    Inflammation can promote the build-up of toxic proteins and promote insulin resistance, she said, so less inflammation can improve brain function.

    The study was published this week in The Proceedings of the National Academy of Sciences.

    A new study by the University of Münster is looking at the effects of eating unsaturated fats from fish, which is beneficial because it is high in omega-3 fatty acids.   Omega-3 is considered “good” fat and may delay the onset of diseases like dementia and Alzheimer’s.

    This blog - Sports Geezer - also wrote about calories and memory. I love this blog.  The writing is breezy and covers a wide range of health and lifestyle topics.

    Do you think increasing calories hurts memory performance? Have you noticed any changes in your brain performance when eating more?

    eeeeeeeeeeeeeeeeeuuuuuuuuuh I eat less calories than a normal people have to eat. And I have to work twice the time that I used to, and lost a lot of capacities, and have problem of concentration. This began at the exact moment when my calories intake decrease... So I don't know if this study is really relevant for others, but for myself, it doesn't work !

    I have a friend who do the contrary : she ate not enough calories, and now, she eats more than 2000, and she really feels better.

    To conclude, I think that eating well, on a healthy manner with not too much fat and sugar is the right think to do. But don't restrict too much !

  • EVERLASTINL0VE@xanga

    even more a reason to eat less!

    The problem with Healthkicker publishing this, is that all of the idiots out there who say shit like "oh ana make me thin. im going 2 eat 500 caloriez today", will take this seriously. People with "fake" issues like that are going to see this as an open door, a way to glorify their eating.

    Eating less doesnt mean starving yourself, and this is really only true for people who are already healthy.

    Using myself as an example, I weigh 262 pounds. My BMR allows for me to eat up to 3,000 calories per day with no consequences. So I reduce my intake to about 1,400-2,000 per day for weight loss. If I eat below 1,400 I feel like crap.

    That is going to prove to be the same for other people too, not just overweight people, but anyone that thinks restricting means starving, and that their memory function will improve or some crap.

    But yeah, eating a lot of food is going to hurt your body's performance in everyway. Eating less (but still in a HEALTHY AND NORMAL) range, is going to improve your body's performance.

  • SicTransitGloria19@xanga

    you can still eat less calories WITHOUT starving yourself. its watching what you eat. I think its eating good vs. eating shit. if you eat bad, your brain is gonna be warped. whats it fueling off of anyway?

  • Mercredi@lovelyish

    I think this entry can be really dangerous when I think about all these girls who make stupid stupid crash diets...

    i eat around 2500 kcal/day. I used to eat less and know I can concentrate much longer

    (The first comment is about me lol)

  • Captivating_Catastrophe08@xanga

    @peacelove__CALLIE@xanga - It's not a "fake" issue. Its all a mindset and I hate how people are so ignorant and think "why do you just eat" its NOT that simple.


    I do agree that ana is wrong, dont get me wrong - everything else you said was 100% true. I agree totally.

  • Mercredi@lovelyish

    @Captivating_Catastrophe08@xanga - I think she's not talking about anorexic people but about a lot of girls who see it as a solution to lose weight.

    it's so bad. I've had a kind of ED. now I'm fine with my body but it scares me to read things like that...

  • peacelove__CALLIE@xanga

    @Captivating_Catastrophe08@xanga - Oh no, I mean the people who simply pretend. Those are the people that are going to turn this into something disastrous. 

  • Captivating_Catastrophe08@xanga

    @Mercredi@lovelyish - I know but people gotta be careful how they word things because what she said and what she meant came out almost totally different. - I was just saying I hate how people think its a fake condition - Its NOT - but w/e - I do agree too many girl look at it as an easy way to lose weight and end up with a mental problem

  • Captivating_Catastrophe08@xanga

    @peacelove__CALLIE@xanga - I understand what you meant now, I didn't mean to be mean to you if I was I apologize. I think healthy kicker should have a post about ED's and other dangerous eating habbits -

  • JoeytheGenie@xanga

    it's not really the amount of calories you intake but the kind you intake. my friend eats crappy foods ex. oreo caksters (sp?) (250/pack where each thing is tiny) and she feels like crap, she falls asleep in class way more than myself and she sleeps more during the night. I eat as much as a 6ft guy but everything I eat is healthy and I feel great, I run and I have pretty good memory.

    People need to be careful when interpreting this study as eating too little is definitely not good for you either. In fact, a lack of food can cause your concentration to decrease. I think that a 30% caloric reduction (such as mentioned in the study) is a good, reasonable, and healthy ideal.

    I have struggled with an eating disorder, EDNOS (purging type), for the last three years. I have days where I don't eat very much at all (~800 calories) and days that are in excess of 2000. Part of my disorder involves a cycle of overeating (and usually throwing up) one day and then overly restricting the next day.

    I do notice that my concentration and mood are much better on the days that I eat less (~1000 calories). My memory also seems to be improved and my outlook on life is generally more positive. However, if I continue for several days without eating much, my mood, memory, and outlook begin to degrade and I spiral downwards.

    The best solution is to eat a healthy range of calories for your body each and every day.

    @peacelove__CALLIE@xanga - Well said!

  • s2__light_as_a_feather__s2@xanga

    i have an eating disorder, and i notice on the days i fast i feel like all my senses in general are sharper.. maybe from the absence of food? the days i eat and i get up to 600-800 calories, i just feel disgusting and sluggish.

  • jojoho@xanga

    sherlock holmes was right; thinking with a full stomach does not work well for me as well.
