The study aimed at determining, in lean tissues from nonobese rats, whether physiological hyperleptinemia with leptin-induced reduced caloric intake and/or calorie restriction (CR) per se: 1) enhance mitochondrial-energy metabolism gene transcript levels and oxidative capacity; and 2) reduce triglyceride content. Liver and skeletal muscles were collected from 6-month-old Fischer 344 rats after 1-wk leptin sc infusion (0.4 mg/kg . d: leptin + approximately 3-fold leptinemia vs. ad libitum-fed control) or moderate CR (-26% of those fed ad libitum) in pair-fed animals (CR). After 1 wk: 1) leptin and CR comparably enhanced transcriptional expression of mixed muscle mitochondrial genes (P < 0.05 vs. control); 2) CR independently increased (P < 0.05 vs. leptin-control) hepatic mitochondrial-lipooxidative gene expression and oxidative capacity; 3) hepatic but not muscle mitochondrial effects of CR were associated (P < 0.01) with increased activated insulin signaling at AKT level (P < 0.05 vs. leptin-control); 4) liver and muscle triglyceride content were comparable in all groups. In additional experiments, assessing time course of posttranscriptional CR effects, 3-wk superimposable CR (P < 0.05): 1) increased both liver and muscle mitochondrial oxidative capacity; and 2) selectively reduced muscle triglyceride content. Thus, in nonobese adult rat: 1) moderate CR induces early increments of mitochondrial-lipooxidative gene expression and time-dependent increments of oxidative capacity in liver and mixed muscle; 2) sustained moderate CR alters tissue lipid distribution reducing muscle but not liver triglycerides; 3) mitochondrial-lipid metabolism changes are tissue-specifically associated with hepatic AKT activation; 4) short-term physiological hyperleptinemia has no independent stimulatory effects on muscle and liver mitochondrial-lipooxidative gene expression. Increased lean tissue oxidative capacity could favor substrate oxidation over storage during reduced nutrient availability.

We compared the effects of calorie restriction (CR) and cyclophosphamide (CTX) on the progression of lupus nephritis and immunological changes in NZB/NZW F1 mice. Ad libitum (AL)/CTX and CR delayed onset of proteinuria and significantly decreased serum levels of anti-dsDNA, anti-histone, and circulating immune complex antibodies. CTX and CR prevented the increase in and activation of B cells, the decline in CD8(+) T cells, and maintained a higher proportion of naive CD4(+) and CD8(+) cells. MHC class I antigen and LFA-1 expression on CD8(+) T cells and MHC class II antigen on B cells were also decreased. AL/CTX and CR prevented the increase in production of IL-10 and up-regulated IL-2 production in T cells ex vivo. We concluded that both CR and CTX can delay the onset of autoimmune disease, in part by maintaining higher numbers of naive T cells and the immune responsiveness of T cells and decreasing the proportion of B cells.

OBJECTIVE: The immunologic effects of isocaloric reduced- and low-fat diets and a voluntary calorie-restricted low-fat diet resulting in weight loss were compared to the immunologic effects of an average American diet in hyperlipidemic individuals. METHODS: Ten hyperlipidemic subjects were studied during three six-week weight maintenance phases: baseline (BL) [35% fat [14% saturated fat (SFA), 13% monounsaturated fat (MUFA), 8% polyunsaturated fat (PUFA)] and 147 mg cholesterol (C)/1000 kcal], reduced-fat (RF) [26% fat (4% SFA, 11% MUFA, 11% PUFA) and 45 mg C/1000 kcal], and low-fat (LF) [15% fat (5% SFA, 5% MUFA, 3% PUFA) and 35 mg C/1000 kcal] diets followed by 12-week, low-fat calorie reduced phase (LFCR). RESULTS: During the last phase, the subjects' weight significantly decreased (p = 0.005). Cholesterol levels were significantly reduced during all phases, compared to BL diet (p < 0.05). Delayed-type hypersensitivity (DTH) was assessed using Multi-test CMI. Maximum induration diameters were 22.7, 25.4, 30.5, 34.5 mm for BL, RF, LF and LFCR diets, respectively. Subjects on the LFCR diets had significantly higher DTH compared to the BL diet (p = 0.005). No significant effect of diet was observed on lymphocyte proliferation or interleukin (IL)-1, IL-2 and prostaglandin (PG) E(2) production. CONCLUSIONS: These data suggest that low-fat diets (15% energy), under conditions which result in weight loss, do not compromise and may enhance the immune response of middle-aged and elderly hyperlipidemic subjects. The results of this study provide support for the hypothesis that moderate caloric restriction in humans may have a beneficial effect on cell-mediated immunity such as those reported in calorie-restricted rodents.

FASTING / LOW CALORIE PROGRAMS
on the Adriatic Coast
The Anti-Aging Fasting Program consists of a 7-28 days program (including 3 - 14 fasting days). 7-28-day low-calorie diet program is also available .

  Conclusion: the whole anti-aging program
    9.1 Modifying your personal aging curve
      Average life span increment. Expert evaluation.
     
Periodic fasting and caloric restriction can add 40 - 50 years to your lifespan
Regular intake of anti-aging drugs can add 20-30 years to your lifespan
Good nutrition (well balanced, healthy food, individually tailord diet) can add 15-25 years to your lifespan
High-tech bio-medicine service can add 15-25 years to your lifespan
Quality of life (prosperity, relaxation, regular vocations) can add 15-25 years to your lifespan
Regular exercise and moderate physical activity can add 10-20 years to your lifespan
These approaches taken together can add 60-80 years to your lifespan, if you start young (say at age 20). But even if you only start later (say at 45-50), you can still gain 30-40 years
