Za mano je drugi, tokrat 3 dnevni post, več pa ni šlo, ker mi je te dni premrzlo :-)

Re: Gromov 7 dnevni post eksperiment

Daljši post za "navadne" ljudi mi je jasen, zakaj mora trajat toliko časa. Prvo mine nekaj dni, da pride človek v ketozo, potem pa nekaj dni, da avtofagija spuca sistem.

Ni pa mi jasno, zakaj bi nekdo, ki je že v ketozi in prekipeva od zdravja, moral tako dolgo furat post? So še druge prednosti od avtofagije?

Re: Gromov 7 dnevni post eksperiment

The cardiovascular, metabolic and hormonal changes accompanying acute starvation in men and women.
Webber J1, Macdonald IA.

Abstract

The effect of fasting for 12, 36 and 72 h was studied in twenty-nine healthy subjects (seventeen women and twelve men). Measurements were made of cardiovascular variables, metabolic rate, respiratory exchange ratio, plasma metabolites, insulin, thyroid hormones and catecholamines. During starvation there were no significant changes in blood pressure, whilst heart rate (beats/min) increased at 36 h and remained elevated after 72 h (12 h 62.5 (SE 1.8), 36 h 68.0 (SE 1.9), 72 h 69.2 (SE 1.8); P < 0.001). Forearm blood flow (FBF) increased progressively from 3.32 (SE 0.20) to 6.21 (SE 0.46) ml/100 ml per min (P < 0.001). Resting metabolic rate (kJ/min) was significantly increased after 36 h of starvation (12 h 4.60 (SE 0.14), 36 h 4.88 (SE 0.13), P < 0.001), but was not significantly different from the 12 h value after 72 h (72 h 4.72 (SE 0.15) P = 0.06). The respiratory exchange ratio fell progressively from 0.80 to 0.76 to 0.72 (P < 0.001). Blood glucose fell, whilst plasma glycerol and beta-hydroxybutyrate rose and plasma lactate did not change. Plasma insulin and free triiodothyronine fell during starvation. Plasma adrenaline and noradrenaline were unchanged at 36 h, but were significantly increased after 72 h. Both sexes showed a similar pattern of response to starvation, although absolute values of blood pressure, forearm blood flow, metabolic rate and plasma catecholamines were higher in men than women. Acute starvation produces profound cardiovascular and metabolic changes which are not explained by the accompanying hormonal changes.

Alternate-day fasting in nonobese subjects: effects on body weight, body composition, and energy metabolism.
Heilbronn LK1, Smith SR, Martin CK, Anton SD, Ravussin E.
Author information
Abstract
BACKGROUND:

Prolonged dietary restriction increases the life span in rodents. Some evidence suggests that alternate-day fasting may also prolong the life span.
OBJECTIVE:

Our goal was to determine whether alternate-day fasting is a feasible method of dietary restriction in nonobese humans and whether it improves known biomarkers of longevity.
DESIGN:

Nonobese subjects (8 men and 8 women) fasted every other day for 22 d. Body weight, body composition, resting metabolic rate (RMR), respiratory quotient (RQ), temperature, fasting serum glucose, insulin, free fatty acids, and ghrelin were assessed at baseline and after 21 d (12-h fast) and 22 d (36-h fast) of alternate-day fasting. Visual analogue scales were used to assess hunger weekly.
RESULTS:

Subjects lost 2.5 +/- 0.5% of their initial body weight (P < 0.001) and 4 +/- 1% of their initial fat mass (P < 0.001). Hunger increased on the first day of fasting and remained elevated (P < 0.001). RMR and RQ did not change significantly from baseline to day 21, but RQ decreased on day 22 (P < 0.001), which resulted in an average daily increase in fat oxidation of > or =15 g. Glucose and ghrelin did not change significantly from baseline with alternate-day fasting, whereas fasting insulin decreased 57 +/- 4% (P < 0.001).
CONCLUSIONS:

Alternate-day fasting was feasible in nonobese subjects, and fat oxidation increased. However, hunger on fasting days did not decrease, perhaps indicating the unlikelihood of continuing this diet for extended periods of time. Adding one small meal on a fasting day may make this approach to dietary restriction more acceptable.

Re: Gromov 7 dnevni post eksperiment

Effects of meal frequency on metabolic profiles and substrate partitioning in lean healthy males.
Munsters MJ1, Saris WH.
Author information
Abstract
INTRODUCTION:

The daily number of meals has an effect on postprandial glucose and insulin responses, which may affect substrate partitioning and thus weight control. This study investigated the effects of meal frequency on 24 h profiles of metabolic markers and substrate partitioning.
METHODS:

Twelve (BMI:21.6 ± 0.6 kg/m(2)) healthy male subjects stayed after 3 days of food intake and physical activity standardization 2 × 36 hours in a respiration chamber to measure substrate partitioning. All subjects randomly received two isoenergetic diets with a Low meal Frequency (3 ×; LFr) or a High meal Frequency (14 ×; HFr) consisting of 15 En% protein, 30 En% fat, and 55 En% carbohydrates. Blood was sampled at fixed time points during the day to measure metabolic markers and satiety hormones.
RESULTS:

Glucose and insulin profiles showed greater fluctuations, but a lower AUC of glucose in the LFr diet compared with the HFr diet. No differences between the frequency diets were observed on fat and carbohydrate oxidation. Though, protein oxidation and RMR (in this case SMR + DIT) were significantly increased in the LFr diet compared with the HFr diet. The LFr diet increased satiety and reduced hunger ratings compared with the HFr diet during the day.
CONCLUSION:

The higher rise and subsequently fall of insulin in the LFr diet did not lead to a higher fat oxidation as hypothesized. The LFr diet decreased glucose levels throughout the day (AUC) indicating glycemic improvements. RMR and appetite control increased in the LFr diet, which can be relevant for body weight control on the long term.
