Gode og dårlige argumenter i kostholdsdebatten
Kostholdsdebatten i Norge, spesielt i media, reduseres ofte til; ”lavfett mot lavkarbo – hva er best?” Dette skyldes nok i stor grad manglende evne til å takle diskusjoner på begge sider av saken. En nylig vist debatt, send på NRK, gikk omtrent slik; lavkarbo, lite fett, Birger Svihus, lavkarbo, lite fett, lavkarbo, lite fett, Birger…

Lack of balls or lack of brains?
In my last post I hinted strongly at the occurrence of cognitive dissonance in a recent editorial. I don’t actually think there is much dissonance out there in the world of science. People aren’t really suffering emotional distress from feelings of holding conflicting ideas. Those who sense something is wrong usually acknowledge it and resolve…

Historien om Lindeberg og Kitava, og hva vi kan lære av den
Når en dyrepasser skal sørge for god helse hos sine dyr er det én grunnleggende regel å følge; dyrene må få den maten de ville spist i naturen og som de dermed er best tilpasset. Man kan ikke fostre opp en tiger på plantekost eller en kjempepanda på kjøtt. Man kan helle ikke fostre opp…

Hva er egentlig problemet med rødt kjøtt?
Et nylig oppslag i Aftenposten holder liv i debatten rundt de Norske kostholdsrådene og spesielt debatten omhandlende rødt kjøtt. I følge Aftenposten sin artikkel er myndighetene overbevist om at rødt kjøtt er skadelig, men ingen vet hvorfor. Denne posten står opprinnelig på min andre blogg, men passer bedre inn her. Jeg har gjort noen tilføyninger…

Kosthold og helse
Alle deler av deg, hver minste lille celle og hvert minste lille molekyl er laget av maten du spiser. Mat er byggesteiner. Ikke nok med det, maten inneholder også energien som trengs for å bruke disse byggesteinene og for å drive alle prosessene som utgjør oss. Vi trenger byggesteiner fordi kroppen vår er i konstant…

You want cognitive dissonance? I’ll give you cognitive dissonance!
The latest issue of Obesity offers both welcome rationality, important discussions and good chances of some decent hair pulling. It features an editorial by Jean-Pierre Flatt from the Department of Biochemistry and Molecular Biology, University of Massachusetts. Flatt gives us an insight into some important misconceptions about obesity. He even made us a list of…

Spring cleaning, truth and disagreements
There! Spring cleaning. All freshened up – away with bricks and Banksy and bombing. The truth We are all confused (some more than others) about what to eat – which foods are good for us and which are not. We’d all like to know this, to learn once and for all which foods give us the…

Angående konflikter og sannheter
Om sannheter Hvis du er interessert i helse og vil vite hvem som har rett og hvem som tar feil med henhold til helse, må du forstå det følgende. Noen ting i verden er svart/hvitt, rett og galt. Noen ting er fullstendig uten nyanser. Når én ting er rett, er alt annet galt. Det finnes sannheter…

My beloved science and me
I am no expert on anything, except perhaps on being me, of which I have an entire lifetime of experience. I don’t know much about biochemistry, about anthropology, anatomy or physiology in general. I got through my entire low quality typically Norwegian education in sport sciences almost completely without taking notes (it’s difficult to listen…

The setpoint hypothesis revisited
The homeostasis (hō’mē-ō-stā’sĭs): The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. Humans are warm blooded and the enzymes that make us, require a certain temperature to operate optimally. The water and ion concentration of cells must remain at a certain level to allow for normal cellular…

Kurt Harris, the messiah, the hype and the throwing of scales
I think Kurt Harris is a smart man and makes some very good points now and then, not to mention his reading list resembles my own. But reading his blog recently I keep thinking of Monty Pythons Life of Brian. For those less versed in the film (shame on you!), Brian is mistaken for the…

Hva er egentlig problemet med rødt kjøtt? (In Norwegian)
istockphoto Mandag 31. januar la Nasjonalt råd for ernæring frem rapporten, ”Kostråd for å fremme folkehelsen og forebygge kroniske sykdommer.” Rapporten er en vitenskapelig gjennomgang av kostens påvirkning på en rekke sykdommer og helsetilstander, og gir konkrete råd om forebygging. Blant rådene er en anbefaling om restriksjon i inntaket av rødt kjøtt. Begrunnelsen er at…

New dietary guidelines – the fairies are rejoicing
Nonsense, n; That which is not sense; spoken or written words which make no sense or convey absurd ideas; also, absurd or senseless action. I am writing nonsense, but it is because no sense within my mind will answer the purpose. Hawthorne (1871) All around are heated discussions and angry tweeters, heads are being slammed…

What is the best exercise for fat loss? Part V – the conclusion
I wondered what the best exercise for fat loss was. I honestly didn’t know the answer, but now feel I have acquired a more thorough understanding. As a scientist I ask questions I want answered and work to find the answers. However, all this digging in the details and nerding about does not mean fat…

What is the best exercise for fat loss? Part IV
The biasI have this theory. In the last post I concluded that there is sufficient data for recommending high intensity exercise in favor of low intensity for fat loss. Admittedly, the data in support of this is not strong. It is there, but I would not bet my life on it yet. I might be…

What is the best exercise for fat loss? Part III
For some reason it makes intuitive sense to me that high intensity exercise is better for fat loss than low intensity, but I do not quite know how this came to make sense. High intensity exercise will cause a primary burning of glucose and so high intensity exercise will make our muscles better at taking…

Intermission – religion and science
Some thoughts on the brink of a new year. An intermission in the exercise for fat loss rambling was at its place. There are people in this world, quite a few people, who would let their children die in the hands of a holy man rather than have them live by the hands of a…

What is the best exercise for fat loss? Part II
Energy expenditure – does it count? No current treatment for obesity reliably sustains weight loss, perhaps because compensatory metabolic processes resist the maintenance of the altered body weight. Leibel, Rosenbaum and Hirsch 1995 [1] The energy For some background reading on energy, this might be of interest. Most endurance exercise apparatus found in a gym…

What is the best exercise for fat loss?
You’d think this question was easy to answer after studying exercise and health for many years. You’d think I would know. I would think I would know, but when asking myself the question recently, it struck me that I didn’t. I can make a calculated guess, but I should know. What sort of exercise would…

Play
Let’s face it, we are social animals. Being forced to solitary living is considered a punishment and rightly so. As social animals we play, both as young and as adults. Play builds social skills, it makes sure our neurons are properly connected and it builds and protects our body. With ever growing focus on lifestyle…
