Studie om fettfri yoghurt. (Fantastiska resultat!)

[Pellefant]

Researchers found that obese adults who ate three servings of fat-free yogurt a day as part of a reduced-calorie diet lost 22 percent more weight and 61 percent more body fat that those who simply cut calories and didn’t bone up on calcium. Yogurt eaters also lost 81 percent more fat in the stomach area than non-yogurt eaters.

Not only did yogurt help the study participants lose more weight — the average weight loss was 14 pounds — they were about twice as effective at maintaining lean muscle mass.

The results appear in the April issue of the International Journal of Obesity

Finns det någon relevans i detta? Vad kan det bero på i så fall?

"The study was supported by the Bell Institute of Health and Nutrition, General Mills Inc., which makes Yoplait."

He, he.

Hursomhelst, ett ökat kalciumintag ökar fettmängden i avföringen:

"Observational studies have shown an inverse association between dietary calcium intake and body weight, and a causal relation is likely. However, the underlying mechanisms are not understood. OBJECTIVE: We examined whether high and low calcium intakes from mainly low-fat dairy products, in diets high or normal in protein content, have effects on 24-h energy expenditure (EE) and substrate oxidation, fecal energy and fat excretion, and concentrations of substrates and hormones involved in energy metabolism and appetite. DESIGN: In all, 10 subjects participated in a randomized crossover study of three isocaloric 1-week diets with: low calcium and normal protein (LC/NP: 500 mg calcium, 15% of energy (E%) from protein), high calcium and normal protein (HC/NP: 1800 mg calcium, 15E% protein), and high calcium and high protein (HC/HP: 1800 mg calcium, 23E% protein). RESULTS: The calcium intake had no effect on 24-h EE or fat oxidation, but fecal fat excretion increased approximately 2.5-fold during the HC/NP diet compared with the LC/NP and the HC/HP diets (14.2 vs 6.0 and 5.9 g/day; P < 0.05). The HC/NP diet also increased fecal energy excretion as compared with the LC/NP and the HC/HP diets (1045 vs 684 and 668 kJ/day; P < 0.05). There were no effects on blood cholesterol, free fatty acids, triacylglycerol, insulin, leptin, or thyroid hormones. CONCLUSIONS: A short-term increase in dietary calcium intake, together with a normal protein intake, increased fecal fat and energy excretion by approximately 350 kJ/day. This observation may contribute to explain why a high-calcium diet produces weight loss, and it suggests that an interaction with dietary protein level may be important."

Att en studie är sponsrad av ett företag som tillverkar en produkt med anknytning måste inte betyda att studien är värdelös; det kan vara så att företaget vill belysa sin produkts egenskaper och ha en vetenskaplig studie som backar upp sina påståenden.

Nu ska jag äta 3 st 180 grams( three 6-ounce servings ) fettfri yoghurt om dagen, som de gjorde i undersökningen kan ju inte skada. Drar ned motsvarande kcal på annat.

Men vad menar de med "fat free", är svensk 0,5% yoghurt ok? (Finns väl ingen svensk helt fettfri? vad jag vet)

Verkar kunna innebära ytterligare nästan ett hekto ned i veckan utan ansträngning.

"So, the regulation will allow a fat-free claim on foods with less than 0.5 grams (g) of fat per serving"

Serving for yogurt = 1 cup = 240mL; runt 2% fett.

Din .5% yogurt har ännu mindre fett, trots vad amerikanerna får kalla för fettfri.

Finns en hel drös Svenska fettfria. Nya Arla Mini, den med sukraralos är fett fri. Viktväktarnas från Skånemejerierna är fettfri. Den är heller nte smaksatt utan helt naturell.

Finska Valio har en hel serie etc.
