Achieving Satiety

[Guest guest]

Hi folks:

Fairly obvious I suppose, but nice to see it demonstrated. And

realize that the 12% reduction mentioned is HUGE ......... if

applied to a full day's intake it amounts to about four times as much

as the legendary (notorious?) half a banana a day, previously

discussed (argued about?) here ; ^ )))

" Salad and satiety: Energy density and portion size of a first-course

salad affect energy intake at lunch.

Rolls BJ, Roe LS, Meengs JS.

Abstract Objective We tested the effect on meal intake of varying the

energy density and portion size of a compulsory first-course salad.

Design The study used a randomized crossover design. Subjects/setting

Forty-two women from the State College, PA, university community ate

lunch in the laboratory once per week for 7 weeks. Intervention Lunch

comprised one of six first-course salads, or no salad in the control

condition, followed by a main course of pasta. Subjects were required

to consume the entire salad, but ate as much pasta as they wanted.

The salads varied in energy density (0.33, 0.67, or 1.33 kcal/g) and

portion size (150 or 300 g). The energy density of the salad was

reduced by changing the amount and type of dressing and cheese. Main

outcome measures Energy intake and ratings of hunger, satiety, and

food characteristics were measured. Statistical analyses performed

Outcomes were analyzed using a linear mixed model with repeated

measures. Results: Compared with having no first course, consuming

the low-energy-dense salads reduced meal energy intake (by 7% for the

small portion and **** 12% **** for the large), and consuming the

high-energy-dense salads increased intake (by 8% for the small

portion and 17% for the large). When two salads with the same number

of calories were compared, meal intake was decreased when the large

portion of the lower-energy-dense salad was consumed. Conclusions

Eating a low-energy-dense first course enhances satiety and reduces

meal energy intake. Consuming a large portion of a low-energy-dense

food at the start of a meal may be an effective strategy for weight

management.
