Större viktnedång med diet rikare på naturlig fruktos än fruktosfattig kost

[King Grub]

One of the proposed causes of obesity and metabolic syndrome is the excessive intake of products containing added sugars, in particular, fructose. Although the ability of excessive intake of fructose to induce metabolic syndrome is mounting, to date, no study has addressed whether a diet specifically lowering fructose but not total carbohydrates can reduce features of metabolic syndrome. A total of 131 patients were randomized to compare the short-term effects of 2 energy-restricted diets-a low-fructose diet vs a moderate natural fructose diet-on weight loss and metabolic syndrome parameters. Patients were randomized to receive 1500, 1800, or 2000 cal diets according to sex, age, and height. Because natural fructose might be differently absorbed compared with fructose from added sugars, we randomized obese subjects to either a low-fructose diet (<20 g/d) or a moderate-fructose diet with natural fruit supplements (50-70 g/d) and compared the effects of both diets on the primary outcome of weight loss in a 6-week follow-up period. Blood pressure, lipid profile, serum glucose, insulin resistance, uric acid, soluble intercellular adhesion molecule-1, and quality of life scores were included as secondary outcomes. One hundred two (78%) of the 131 participants were women, mean age was 38.8 ± 8.8 years, and the mean body mass index was 32.4 ± 4.5 kg/m(2). Each intervention diet was associated with significant weight loss compared with baseline. Weight loss was higher in the moderate natural fructose group (4.19 ± 0.30 kg) than the low-fructose group (2.83 ± 0.29 kg) (P = .0016). Compared with baseline, each intervention diet was associated with significant improvement in secondary outcomes. Reduction of energy and added fructose intake may represent an important therapeutic target to reduce the frequency of obesity and diabetes. For weight loss achievement, an energy-restricted moderate natural fructose diet was superior to a low-fructose diet.

Det här var intressant och belyser ett ämne som tidigare har diskuterats med lite negativ klang.

Jag tänker på http://forum.body.se/showpost.php?p=482014&postcount=6 t ex


Efter litet googlande verkar ett normalstort äpple innehålla ca 5-9g fruktos.

Lite generell info om fruktos för den intresserade: http://forum.body.se/showthread.php?t=4132

Lite liknande upplägg som den här studien:

Abstract. The consumption of specific foods in energy-restricted diets
may affect the weight loss process. The purpose of this research was to
evaluate whether obese women following two hypocaloric diets with distinct
fruit content differ in weight loss and metabolic responses. Fifteen
obese women were included, who were randomly assigned to follow a
low or a high-fruit energy-restricted diet for 8 weeks. The main outcome
variables were weight and fat losses. Metabolic measurements concerning
macronutrient oxidation were also assessed by using 13C labelled fructose
and indirect calorimetry. The induced weight loss was similar for
both diets (6.9 ± 2% vs. 6.6 ± 2%, p = 0.785). Both experimental diets
similarly improved the lipid plasma profile in the participants, but the
cholesterol fall was higher in obese subjects receiving the diet containing
more fruit. No statistical differences in lipids carbohydrates and 13C
labelled fructose utilisation were observed, but protein oxidation was differently
affected by the experimental diets. The compensatory effects of
the associated fibre/fructose intake may explain the lack of a specific effect
of the fruit amount on hypocaloric diets designed to weight loss, although
the increased fibre content from enriched fruit diets may be involved in the
favourable effects on cholesterol plasma levels.

Hmm, intressant.

Synd att jag blir illamående av äpplen bara några minuter efter att jag käkat ett.

Tur de finns fler frukter då :)

Varför är det synd? Menar inget drygt, jag bara undrar vad i studien som plötsligt gör det synd att du inte kan äta äpplen?

102 av deltagarna var kvinnor, feta, medelålders, små skillnader i vikt och inga skillnader i hälsoeffekter. Det lilla man kan säga är väl kanske att frukt i kosten, under kontrollerade former och på kort tid, förefaller kunna ha en liten positiv effekt för viktnedgång hos en liknande grupp människor.

Och att en lite högre mängd fruktos inte påverkar negativt vid energiunderskottet.

Nej, alltså det var en helt random kommentar bara :)

Kan någon snälla översätta det där på bättre svenska då mitt engelska är inte min starka sida. Tack uppskattas

Kan man inte bara säga frukt snarare än natural fructose?
Tycker de får det att låta som om det är skillnad på fruktos och fruktos. En apelsin är inte "naturlig fruktos", det är en frukt. Det är nästan som att säga att potatis är naturlig stärkelse :P
