The fruit-and-vegetable fast is primarily a cleansing and normalizing treatment, not a weight-loss diet.
„The fruit-and-vegetable fast is not a weight-loss diet; it is primarily a cleansing and normalizing treatment. Weight loss is associated mainly with burning fat tissue rather than muscle, because fasting has this effect by activating the same processes as a ketogenic diet (reduced carbohydrate intake).”Post warzywno-owocowy nie jest dietą odchudzającą, jest to przede wszystkim kuracja oczyszczająco-normalizująca. Utrata wagi wiąże się ze spalaniem w głównej mierze tkanki tłuszczowej, a nie mięśni, gdyż taką właściwość ma post – aktywując te same procesy, co dieta ketogeniczna (redukcja węglowodanów).

„Weight loss is associated mainly with burning fat tissue rather than muscle, because fasting has this effect by activating the same processes as a ketogenic diet (reduced carbohydrate intake). To maintain the positive results, it is worth making a health-promoting lifestyle change permanent.”Utrata wagi wiąże się ze spalaniem w głównej mierze tkanki tłuszczowej, a nie mięśni, gdyż taką właściwość ma post – aktywując te same procesy, co dieta ketogeniczna (redukcja węglowodanów). By utrwalić korzystne wyniki warto wprowadzić prozdrowotną zmianę stylu życia już na stałe.

Fasting combined with exercise is said to address excess calories and lack of physical activity, which Ewa Dąbrowska identifies as causes of obesity.
„The fruit-and-vegetable fast, combined with exercise, directly addresses the causes of disease: excess calories and too little physical activity. Obesity is a hormonal disorder. Two hormones play a key role: insulin (produced by the pancreas) and cortisol (the stress hormone produced by the adrenal glands).”Post warzywno-owocowy, połączony z ruchem, działa bezpośrednio na przyczyny chorób: nadmiar kalorii i niedobór ruchu. Otyłość to zaburzenie hormonalne. Kluczową rolę odgrywają dwa hormony: insulina (produkowana przez trzustkę) i kortyzol (hormon stresu wytwarzany przez nadnercza).

During fasting, insulin levels fall, which, according to Ewa Dąbrowska, triggers processes that reduce body weight and reverse metabolic diseases.

W czasie postu poziom insuliny spada, co uruchamia procesy redukcji masy ciała i cofania się chorób metabolicznych.

Fasting helps reduce excess fat tissue and may improve the cells’ sensitivity to insulin.
„Fasting helps reduce excess fat tissue and reverses fatty liver. As a result, cells become more sensitive to insulin. This is crucial because insulin resistance underlies many metabolic diseases: type 2 diabetes, atherosclerosis, high blood pressure, lipid disorders, and gout.”Post wspomaga redukcję nadmiaru tkanki tłuszczowej i cofa stłuszczenie wątroby. W efekcie poprawia się wrażliwość komórek na insulinę, co jest kluczowe, ponieważ insulinooporność leży u podstaw wielu chorób metabolicznych: cukrzycy typu 2, miażdżycy, nadciśnienia, zaburzeń lipidowych czy dny moczanowej.

In the context of PCOS, Ewa Dąbrowska writes that fasting helps with weight loss.
„The fruit-and-vegetable fast effectively reduces insulin resistance, lowers insulin and estrogen levels, and helps with weight loss. This can remove the cause of PCOS and restore normal ovarian function.
Weight loss is a basic non-drug element of PCOS treatment, and its effectiveness has been confirmed by numerous scientific studies.”Post warzywno-owocowy skutecznie redukuje insulinooporność, obniża poziom insuliny i estrogenów oraz wspomaga utratę masy ciała. Dzięki temu możliwe jest usunięcie przyczyny PCOS i przywrócenie prawidłowej funkcji jajników.
Utrata masy ciała stanowi podstawowy, niefarmakologiczny element leczenia PCOS – jej skuteczność potwierdzają liczne badania naukowe.

We selected 2 studies with the best, positive results. This is a selection, not a full review of all research.

A meta-analysis found a small increase in HDL levels following interventions that increased fruit and vegetable intake, but did not assess the effectiveness of obesity treatment.
Aim of the study: Overweight and obesity are associated with low levels of high-density lipoprotein (HDL). The occurrence of cardiovascular disease is strongly predicted by HDL. Increased HDL reduces the risk of cardiovascular disease and stroke. Increased fruit and vegetable consumption (FVC) has been proposed to increase HDL in overweight and obesity; however, research outcomes are inconclusive on the effects of FVC on HDL in this population.
Results: We found a small standardized mean difference of FVC on HDL (d = 0.18; 95% confidence interval, 0.06-0.29; z = 3.04, P < .01), minimal heterogeneity (Q = 6.10, P = .30, I = 18.05%), and possible publication bias. Moderator analyses indicated that masking of data collectors (Z = 3.73, P = .05) and intention-to-treat analysis (Z = 3.73, P = .05) significantly moderated the overall summary effect. Given that only 1 research team reported masking and intention to treat, these results should be interpreted with caution. There was a small increase in HDL across studies (d = 0.18) in overweight and obese individuals. The effect size may be limited because of the small number of studies included in this meta-analysis. Nonetheless, obese and overweight individuals should be encouraged to increase their FVC to improve HDL and lower cardiovascular risk factors.

In a 10-week intervention, people with overweight or obesity were advised to follow a diet rich in fruits and vegetables. Their intake increased, but the reported results do not provide information on changes in body weight.
Aim of the study: Thus far, no studies have examined the relationship between fruit and vegetable (F and V) intake, urinary metabolite quantities, and weight change. Therefore, the aim of the current study was to explore changes in urinary metabolomic profiles during and after a 10-week weight loss intervention where participants were prescribed a high F and V diet (7 servings daily).
Results: Energy intake was significantly lower (p = 0.02) at week 10 compared with baseline. Total F and V intake was significantly higher at week 2 and week 10 (p < 0.05). In total, 123 urinary metabolites were quantified. At week 10, 21 metabolites showed significant changes relative to baseline. Of these, 11 metabolites also significantly changed at week 2. These overlapping metabolites were acetic acid, dimethylamine, choline, fumaric acid, glutamic acid, L-tyrosine, histidine, succinic acid, uracil, histamine, and 2-hydroxyglutarate. Ridge Classifier and Linear Discriminant Analysis provided best prediction accuracy values of 0.96 when metabolite level of baseline was compared to week 10. Urinary metabolites quantified represent potential candidate biomarkers of high F and V intake, associated with a reduction in energy intake. Further studies are needed to validate these findings in larger population studies.

„These "empty" calories then replace other foods such as whole grains, fruits, and vegetables that are the main source of essential nutrients. But added sugar is not limited to soft drinks. Added fructose, as in high-fructose corn syrup or just plain sugar (sucrose, which is 50% glucose and 50% fructose), is found in a wide variety of processed foods such as breakfast cereal, juices, jellies and jams, candy, baked goods, sauces, desserts, and even ready-made dinners and processed meat. Fructose tastes sweet but does not satisfy hunger as well as more nutritious foods.”These "empty" calories then replace other foods such as whole grains, fruits, and vegetables that are the main source of essential nutrients.
