Nut diet cycles > CR?

[Guest guest]

Hi All,

Might the below not yet in Medline not pdf-available paper suggest that going

through cycles of eating and not eating nuts result in net CR?

¡°Does regular walnut consumption lead to weight gain?¡± Maybe, yes, but, ¡°The

weight gain from incorporating walnuts into the diet ... was less than the

weight

loss from withdrawing walnuts from the diet¡±?

Does regular walnut consumption lead to weight gain?

Abstract:

Studies consistently show the beneficial effects of eating nuts, but as

high-energy

foods, their regular consumption may lead to weight gain. We tested if daily

consumption of walnuts (approximately 12% energy intake) for 6 months would

modify

body weight and body composition in free-living subjects. Ninety participants in

a

12-month randomized cross-over trial were instructed to eat an allotted amount

of

walnuts (28¨C56g) during the walnut-supplemented diet and not to eat them during

the

control diet, with no further instruction. Subjects were unaware that body

weight

was the main outcome. Dietary compliance was about 95% and mean daily walnut

consumption was 35 g during the walnut-supplemented diet. The

walnut-supplemented

diet resulted in greater daily energy intake (557 kJ (133 kcal)), which should

theoretically have led to a weight gain of 3¡¤1 kg over the 6-month period. For

all

participants, walnut supplementation increased weight (0¡¤4 (se 0¡¤1) kg), BMI

(0¡¤2

(se 0¡¤1) kg/m2), fat mass (0¡¤2 (se 0¡¤1) kg) and lean mass (0¡¤2 (se 0¡¤1)

kg).

But, after adjusting for energy differences between the control and

walnut-supplemented diets, no significant differences were observed in body

weight

or body composition parameters, except for BMI (0¡¤1 (se 0¡¤1) kg/m2). The

weight

gain from incorporating walnuts into the diet (control¡ú ¨C>walnut sequence) was

less than the weight loss from withdrawing walnuts from the diet (walnut¡ú

¨C>control sequence). Our findings show that regular walnut intake resulted in

weight gain much lower than expected and which became non-significant after

controlling for differences in energy intake.
