Study on the Effect of Fish Oil and Appetite

20 normal-weight healthy subjects (10 males, 10 females) were in two periods given 10 of 0.5-mL capsules/day of fish oil and soybean oil for 3 weeks. In the end of each period they were given a standard breakfast and asked to report their appetite on visual analogue scales (VAS) immediately before and after the meal. The results were analyzed in accordance with the paired design under consideration of both supplement sequence and gender.

In a randomized cross-over design, 20 normal-weight healthy subjects (10 males, 10 females) were given 10 of 0.5-mL capsules/day of fish oil and soybean oil for 3 weeks. In the end of each period they were given a standard breakfast and asked to report their appetite on visual analogue scales (VAS) immediately before and after the meal. The results were analyzed in accordance with the paired design under consideration of both supplement sequence and gender.

For 3 weeks 5 g/d in 10 capsules, providing 3.5 g long-chain n-3 fatty acids in the fish oil period. Cross-over between arms with 1 week of wash out

Appetite and satiation were measured by visual analogue scales (VAS), which assessed satiation, hunger, fullness and desire to eat. Each scale was 100 mm in length with words anchored at each end, expressing the most positive and negative rating of each category.

Body weight was measured on the same scale without shoes and wearing light clothing in the morning before breakfast.

Inclusion Criteria: Normal weight (18.5<BMI<25 kg/m2). Healthy. Exclusion Criteria: Subjects taking medication that could influence appetite. Subjects with special nutritional needs e.g. pregnant and lactating, seriously ill or old people. Subjects that had had fish oil-supplements for four weeks prior to the intervention period.
