10 ting du bør vite om det å gå ned i vekt

by Erlend 31. mai 2009 13:43

Så en dokumentar på BBC som hadde dette som tittel (bare på engelsk, da) i dag. Det inneholdt en del kjent informasjon, men også en del jeg ikke visste. Meget interessant.

1. Don’t skip meals
If you skip meals, your brain craves higher-calorie foods; and sub-consciously you’re drawn more to the more fattening foods.

Hjernen blir satt i en slags alarmberedskap når man hopper over et måltid, og det gjør at hjernen prøver å få deg til å spise høykalorimat i stedet for det man normalt ville spise. Dette kan være vanskelig å motstå hvis man ikke vet at det er slik det fungerer.
 

2. Use Smaller Plates
You’ll put less food on your plate, and in turn eat less food. You eat more if you have more food on your plate.

Det er vitenskapelig bevist at hvis du har mindre tallerkener vil du spise opptil 22% mindre mat pr måltid.
 

3. Count Your Calories
Know what calories your food contains! Opt for the lower calorie versions of your favourites. E.g. 
* Black Coffee: 10 Calories; Cappuccino: 100 Calories
* Thin Crust Cheese and Tomato Pizza: 850 Calories; Deep Pan Pepperoni: 1400 Calories
* Bloody Mary Cocktail: 125 Calories; Pina Colada: 280 Calories.

Dette er jo kjent stoff, men gurgle så kjedelig det er å telle kalorier. Men det virker, det er det skumleste!
 

4. Don’t Blame Your Metabolism
Take responsibility yourself! You may be eating more than your body needs – you may be forgetting about the calories in your fruit salad or your fruit smoothies.

I programmet ble det gjort et forsøk der en person bedt om å føre videodagbok, samt skrive opp all mat som ble spist rette etter måltidet. I tillegg måtte personen hver dag drikke en sporingsvæske som kan måle kalori-inntaket, samt levere urinprøve hver dag.

Urinprøvene viste at kaloriinntaket var nesten dobbelt så stort som det personen oppga, enten fordi det ble glemt eller at det ble ansett som unødvendig (frukt).

Konklusjonen er: a) du spiser mer enn kroppen trenger og b) tell kalorier (se punkt 3. over).
 

5. Protein staves off hunger pains
For the medically scientific here; protein causes a release of more PYY hormones than other food types, which suppresses hunger pains more.

Dette var nytt for meg. Altså at proteinrik mat fører til at man føler seg mett lenger, og man unngår i større grad at magen roper SUUUULTEEEEN!
 

6. Soup keeps you feeling fuller for longer
Consider pureeing your food – it stays in your stomach longer, meaning you feel fuller, longer.

Dette var et morsomt forsøk: to grupper mennesker fikk spise nøyaktig samme mat, med den forskjellen at den ene gruppen fikk en tallerken mat med et glass vann til, mens den andre gruppen blandet all maten og glasset med vann i en kjøkkenmikser til en slags suppe.

Resultatet var at magesekken slapp glasset med vann omtrent rett igjennom i den første gruppen, mens magesekken holdt på hele suppen (og var dermed fullere lengere). Dette gjorde at magen til den første gruppen signaliserte til hjernen mye tidligere (flere timer) at “jeg er sulten”.

Hørte jeg “4 pils og en pizza” á la Kristopher Schau??
 

7. The wider the choice, the more you eat
Variety makes you more likely to want to try everything.

Dette er jo kjent fra hotellfrokoster og –lunsjer. Jeg vil ha alt, og helst på en gang! Man risikerer faktisk å spise opptil 30% mer når man har mye å velge mellom. Stort utvalg bør altså være et faresignal for de som ønsker å gå ned i vekt.
 

8. Low fat dairy helps you excrete more fat
Calcium binds to fats, making them insoluble; meaning the fats pass through your body and out the other end!

Igjen et forsøk der personen (faktisk bassisten i Blur, siden han lager ost) spiste samme dietten i to uker, første uka uten og andre uka med meieriprodukter til. Det de så gjorde var å sende avføringen til Nederland for å bli analysert, og resultatene viste en dramatisk forskjell i fettinnholdet.

Det som skjer er at meieriprodukter inneholder kalsium, kalsium binder opp en del av fettet fra maten du spiser, så med andre ord kommer en større del av fettet i maten du spiser ut igjen!

For forsøkspersonen ville 2 kg mer fett (altså 2 KG FETT) komme ut igjen på “naturlig vis” pr år, hvis man i forbindelse med måltidet spiser/drikker meieriprodukter (med kalsium og lavt fettinnhold). Stikkord: ost, skummet melk, Crème fraîche, yoghurt, osv.
 

9. Exercise goes on burning fat, even while you sleep
You burn more fat after exercise, than while exercising. Your body keeps burning it for up to 22 hours after!

Hm, "afterburn"-effekten var jeg faktisk ikke klar over. Musklene bruker altså karbohydrater lagret i kroppen mens du trener fordi de er "lettere tilgjengelig". Etter treningen må karbohydrat-lagrene etterfylles, og i mellomtiden må kroppen bruke av fettlagrene til forbrenningen for å holde kroppen gående. Med andre ord, gå en tur hver dag, og hvis turen medfører at hjertet pumper ekstra og man begynner å svette er det en fordel. Så gjør kroppen resten mens du sover.
    

10. Keep moving and lose weight
Keep yourself active; but don’t eat more because you’re doing more exercise! Instead of sitting while on the phone, wander around. Get off a bus stop earlier and walk the final distance, and take a walk during your lunch break.

Hvis aktiv trening ikke er din greie, gjør det du gjør hver dag litt anderledes, litt mer “aktivt”. Gå i rulletrappen, ikke bare stå der osv. Bruk fantasien!
 

 

I tillegg

Punktene over var altså de 10 punktene fra programmet på BBC. I tillegg har jeg et par punkter jeg vil legge til, uten at noen trenger beskylde meg for å være noen slankeekspert:

11. Spis langsomt

Hvis du spiser fort vil ikke hjernen få beskjed om at du er mett før du har spist for mye.
 

12. Drikk vann

Vann legger en demper på sultfølelsen og er harmløs. I tillegg holder man væskebalansen.
 

Andre ressurser

Her er en artikkel fra 2003 på lommelegen.no om overvekt.

Her er også reklame for en TV-serie jeg så for en tid tilbake. Det er ganske morsomt å se i hvilken grad man kan omprogrammere hjernen. Selve showet er nettopp det; et show. Men det Paul McKenna gjør i TV-serien (og boka) gir resultater, selv om dette kanskje ikke fungerer for alle.

Reglene hans er helt banale, men det er den utvidede forklaringen av hvert punkt og sammenhengen mellom punktene som er poenget:

1. When you are hungry, eat.
2. Eat what you want (not what you think you "should").
3. Eat consciously and enjoy every mouthful.
4. When you are full, stop.

Og bortsett fra det: LYKKE TIL!   Wink
