Wysokie spozycie owoców i warzyw prowadzi do poprawy skladu ciala, parametrow metabolicznych i zmniejszenia ryzyka nadwagi czy otylosci, jak i spadku nadprogramowej wagi. Z reszta nie musisz mi wierzyc na slowo, potwierdzaja to nie tylko moje doswiadczenia, ale rowniez liczne badania naukowe:

Abstract
To determine whether changes in dietary intakes predict weight loss, we studied 80 overweight adults who attended a nutritional counseling program during 6 months of follow-up at a primary health care center in Brazil. Habitual diet was assessed using a validated food frequency questionnaire at baseline and after 6 months. The mean age (+/-SD) of the participants was 46.5 +/- 9.5 years, and their mean body mass index was 29 +/- 3 kg/m(2) at baseline. After 6 months, the differences in body weight and fruit/vegetable intake were -1.4 +/- 3 kg and +/-109 +/- 320 g daily, respectively. Using multiple linear regression models adjusted for age, sex, changes in walking time, and total energy intake, the increased intake of dietary fiber from fruits/vegetables was associated with a greater weight loss (beta1 [95% confidence interval (CI)] = -0.180 [-0.269, -0.091]) after 6 months of follow-up. Similar results were observed for increased intake of vegetables (beta1 [95% CI] = -0.00497 [-0.008, -0.002]) and fruits (beta1 [95% CI] = -0.00290 [-0.005, -0.001]) as predictors of weight loss. The increase of 100 g/d of vegetables and fruits represented a body weight loss of 500 and 300 g after 6 months, respectively (P < .05). Our findings support the relevance of increased intakes of fruits and vegetables that may help avoid weight gain in overweight adults.

Abstract
OBJECTIVE: Despite the alarming increase in the prevalence of obesity, epidemiologic studies that prospectively examine the fruit and vegetable consumption and other lifestyle factors in relation to weight gain (WG) are still insufficient. We explored the associations between fruit and vegetable intake and WG over a 10-year period in an adult Mediterranean population.
METHODS AND PROCEDURES: We performed a 10-year follow-up study with healthy participants (n = 206) aged 15-80 years at baseline in 1994, who participated in a nutrition survey in Valencia, Spain. Data on diet, lifestyle factors, and body weight were obtained in 1994 and 2004 using a food frequency questionnaire (FFQ) and direct measurements.
RESULTS: The average WG over the study period was 3.41 (s.d. 6.9) kg. In multivariate analyses, participants in the third quartile of fruit intake at baseline in 1994 had lower risk of WG> or =3.41 kg compared to those in the lowest quartile (oddsratio (OR) = 0.31, 95% confidence interval (CI), 0.11-0.85; P trend = 0.044). Regarding vegetable intake, the risk of WG was lowest in participants of the fourth quartile (>333 g/day), which had an 84% reduced risk of gaining 3.41 kg weight (OR = 0.18, 95% CI, 0.05-0.66; P trend = 0.017). When the intake of fruits and vegetables was combined, the risk of WG decreased across quartiles, with the lowest risk among those in the fourth quartile (OR = 0.22, 95% CI, 0.06-0.81; P trend = 0.022). Further adjustment for an increased intake of fruits and vegetables over the past 10 years reported by participants in 2004 did not appreciably alter the observed ORs.
DISCUSSION: Dietary patterns associated with a high intake of fruits and vegetables in Mediterranean populations may reduce long-term risk of subsequent WG and obesity among adults.

Abstract
Food preferences play a central role in food choices and consumption. The primary objective of this study was to examine the relationship between children's preferences for fruits and vegetables and their weight status. A total of 341 black children (43% boys; 68% fourth graders) attending low-income, public elementary schools in southeastern Louisiana volunteered to participate. Children were measured for height and weight and completed a survey that sought their preferences for 38 different fruits and vegetables during the fall of 2005. Results indicated that children preferred fruits more than vegetables and that there was a negative association between children's mean fruit and vegetable preference score and their body mass index for age percentile (r=-0.26; P=0.01). Children who reported a very low preference for fruits and vegetables were 5.5 times more likely to be categorized as at risk for overweight or overweight than were those who reported a high preference for fruits and vegetables (odds ratio: 5.5; confidence interval: 1.97 to 15.44; P<0.01). It is believed that food preferences are established early in life; therefore, nutritionists and other health care professionals should promote children's acceptance and intake of fruits and vegetables as a measure to reduce the prevalence of overweight among children.

Tak wiec jak widzisz nie zgadzamy się niestety co do kwestii spozycia owoców, i moim zdaniem błędem jest podejscie stricte teoretyczne, praktyka bowiem już dawno zweryfikowała podobne do Twoich obawy, przynajmniej jeśli mówimy o tzw przykładowym kowalskim / kowalskiej.
Podobnie, wbrew temu co mowisz, nie powinno sie dokonywac 180 stopniowych zwrotów w dietach, a sugerowac wprowadzenie stopniowych, a konsekwentnych zmian.
Co do 17 letniej licealistki - i tutaj chyba sie nie zrozumielismy - to był przykład który miał coś zobrazować, a nie portret psychologiczny autorki tematu. Choc upieram się iz jest to raczej dośc młoda osoba, mozliwe ze lat ma mniej niz 17, a swiadczy o tym sposob formułowania wypowiedzi
