“…26,29,34 However, finding no significant relation in the PBF of the subjects in this study might be because of a small amount of abdominal muscle that was involved in the prescribed resistance trainings compared with previous studies that used a general resistance training for their subjects. 32 In some studies, 29,35 an increased LBM after general resistance training is reported; however, in other studies, 26,32 LBM has not been changed by these exercise trainings.…”

“…Of the studies that have investigated changes in bone mass in response to diet-induced weight loss in overweight or obese adults, the results have been highly variable, with increases, (20)(21)(22)(23)(24) decreases, (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) and no change (22,24,26,30,33,(41)(42)(43)(44)(45)(46)(47)(48)(49) in bone mass being reported. Thus, attempting to draw sound conclusions from these mixed results is extremely difficult.…”

Diet-induced weight loss has been suggested to be harmful to bone health. We conducted a systematic review and meta-analysis (using a random-effects model) to quantify the effect of diet-induced weight loss on bone. We included 41 publications involving overweight or obese but otherwise healthy adults who followed a dietary weight-loss intervention. The primary outcomes examined were changes from baseline in total hip, lumbar spine, and total body bone mineral density (BMD), as assessed by dual-energy X-ray absorptiometry (DXA). Secondary outcomes were markers of bone turnover. Diet-induced weight loss was associated with significant decreases of 0.010 to 0.015 g/cm 2 in total hip BMD for interventions of 6, 12, or 24 (but not 3) months' duration (95% confidence intervals [CIs], -0.014 to -0.005, -0.021 to -0.008, and -0.024 to -0.000 g/cm 2 , at 6, 12, and 24 months, respectively). There was, however, no statistically significant effect of diet-induced weight loss on lumbar spine or whole-body BMD for interventions of 3 to 24 months' duration, except for a significant decrease in total body BMD (-0.011 g/cm 2 ; 95% CI, -0.018 to -0.003 g/cm 2 ) after 6 months. Although no statistically significant changes occurred in serum concentrations of N-terminal propeptide of type I procollagen (P1NP), interventions of 2 or 3 months in duration (but not of 6, 12, or 24 months' duration) induced significant increases in serum concentrations of osteocalcin (0.26 nmol/L; 95% CI, 0.13 to 0.39 nmol/L), C-terminal telopeptide of type I collagen (CTX) (4.72 nmol/L; 95% CI, 2.12 to 7.30 nmol/L) or N-terminal telopeptide of type I collagen (NTX) (3.70 nmol/L; 95% CI, 0.90 to 6.50 nmol/L bone collagen equivalents [BCEs]), indicating an early effect of diet-induced weight loss to promote bone breakdown. These data show that in overweight and obese individuals, a single diet-induced weight-loss intervention induces a small decrease in total hip BMD, but not lumbar spine BMD. This decrease is small in comparison to known metabolic benefits of losing excess weight.

“…In the study by Nakata et al (2008) 57) , vital age became significantly younger, by approximately 5 years, following a diet-only intervention, by 8 years following exercise-only, and by 10 years following a combined exercise plus diet intervention. Large changes in coronary risk factors and physical fitness variables during the intervention contributed substantially to the improvement of vital age in the three groups.…”

“…Therefore, a combination of exercise and diet, which includes the recommended daily intakes of calcium, is suggested for the prevention of bone loss during dieting. In our laboratory, the effects of diet-only or diet plus resistance training on weight loss, whole-body and selected regional bone mineral density (BMD) in 42 obese premenopausal Japanese women was investigated 57) . Following a 14 week intervention period, individuals in the diet group lost 6.2 ± 3.5 kg, while those in the diet plus exercise group lost 8.6 ± 3.6 kg.…”

Japan is one of the most rapidly aging countries in the world. "Healthy Japan 21" is a Japanese government initiative promoting lifestyle-related disease prevention, health promotion, and successful aging. Increasing physical activity participation among older Japanese, the least physically active of any age group, is especially important for preventing frailty and chronic disease, and the associated health care expenditure. Informed by the research we have to date, the following evidence-based conclusions can be drawn relative to exercise and physical activity for the obese population. A combination of aerobic exercise, resistance exercise and physical activities, in addition to proper diet (mostly caloric restriction: 1200 kcal for women and 1680 kcal for men for a certain period of time), is more effective than either form of intervention alone for reducing body weight, visceral fat, blood pressure, and many other negative health-related variables. Exercise habituation in conjunction with proper diet is also most effective for improving vital age. Incorporating and adhering to these lifestyle factors, coupled with adherence to other known health modifiers (reduced stress, improved sleep, etc) will help reduce individual and population obesity and improve national health.
