Almost like spot reduction...........

Hmmmmmmmmmmm.

Exercise-Induced Weight Loss Preferentially Reduces Abdominal Fat.

ABSTRACT MAYO, M. J., J. R. GRANTHAM, and G. BALASEKARAN. Exercise-Induced Weight Loss Preferentially Reduces Abdominal Fat., Vol. 35, No. 2, pp. 207-213, 2003.PURPOSE To investigate whether abdominal fat is reduced in response to substantial weight loss induced by exercise in young obese men.METHODS Thirty obese men (mean age 19.8 +/- 0.6 yr) were evaluated before (pretraining) and after (posttraining) 4 months of regimented training in the Singapore Armed Forces. There were 30 obese male subjects (mean age 19.2 +/- 1.3 yr) without training who were monitored as control subjects. Fat free mass (FFM), fat mass, and percent body fat were determined from skinfold measurements. Differences between pre- and posttraining responses were analyzed with a paired -test.RESULTS Subjects lost 12.0 +/- 3.6 kg ( < 0.001) from pre- to posttraining, which was attributable to a reduction in fat mass ( < 0.001), as FFM was unchanged. Both waist circumference (WC) and hip circumference (HC) decreased ( < 0.01), the reduction in WC (13.7%) being greater than the reduction in HC (7.7%) as reflected by the decrease in waist-to-hip ratio (WHR; < 0.001). These data reveal that large exercise-induced weight losses are associated with maintenance of FFM. The significant reduction in WHR indicates a greater mobilization of abdominal fat and a preferential loss of fat from this region.CONCLUSIONS Large exercise-induced weight loss is associated with a preferential reduction in abdominal fat and a corresponding maintenance of FFM. Such an effect on body composition should reduce disease risk and the eventual weight regain that typically follows diet-induced weight losses with obese subjects.

Definitely interesting.

Reminds me of a study I saw which suggested that fat lost through a dietery caloric deficit resulted in a predominantly visceral fat loss, where are as an exercise based caloric deficit resulted in a more predominantly subcutaneous fat loss.

Chim-chim,


Post a link if you can find it. Many be be interested in that study.

Not quite the study I meant but supports your original well, will keep looking for that other one.

Reduction in obesity and related comorbid conditions after diet-induced weight loss or exercise-induced weight loss in men. A randomized, controlled trial.

BACKGROUND: The independent effects of diet- or exercise-induced weight loss on the reduction of obesity and related comorbid conditions are not known. The effects of exercise without weight loss on fat distribution and other risk factors are also unclear. OBJECTIVE: To determine the effects of equivalent diet- or exercise-induced weight loss and exercise without weight loss on subcutaneous fat, visceral fat skeletal muscle mass, and insulin sensitivity in obese men. DESIGN: Randomized, controlled trial. SETTING: University research center. PARTICIPANTS: 52 obese men (mean body mass index [+/-SD], 31.3 +/- 2.0 kg/m2) with a mean waist circumference of 110.1 +/- 5.8 cm. INTERVENTION: Participants were randomly assigned to one of four study groups (diet-induced weight loss, exercise-induced weight loss, exercise without weight loss, and control) and were observed for 3 months. MEASUREMENTS: Change in total, subcutaneous, and visceral fat; skeletal muscle mass; cardiovascular fitness; glucose tolerance and insulin sensitivity. RESULTS: Body weight decreased by 7.5 kg (8%) in both weight loss groups and did not change in the exercise without weight loss and control groups. Compared with controls, cardiovascular fitness (peak oxygen uptake) in the exercise groups improved by approximately 16% (P < 0.01). Although total fat decreased in both weight loss groups (P < 0.001), the average reduction was 1.3 kg (95% CI, 0.3 to 2.3 kg) greater in the exercise-induced weight loss group than in the diet-induced weight loss group (P = 0.03). Similar reductions in abdominal subcutaneous, visceral, and visceral fat-to-subcutaneous fat ratios were observed in the weight loss groups (P < 0.001). Abdominal and visceral fat also decreased in the exercise without weight loss group (P = 0.001). Plasma glucose and insulin values (fasting and oral glucose challenge) did not change in the treatment groups compared with controls (P = 0.10 for all comparisons). Average improvement in glucose disposal was similar in the diet-induced weight loss group (5.6 mg/kg skeletal muscle per minute) and in the exercise-induced weight loss group (7.2 mg/kg skeletal muscle per minute) (P > 0.2). However, these values were significantly greater than those in the control and exercise without weight loss groups (P < 0.001). CONCLUSIONS: Weight loss induced by increased daily physical activity without caloric restriction substantially reduces obesity (particularly abdominal obesity) and insulin resistance in men. Exercise without weight loss reduces abdominal fat and prevents further weight gain.

It sure does.

Good Info Chimponarope.

We need more info like this to be presenting in this and other sections of the forum IMO.

Glad to be able to put some of my research and studying to good use

I can't seem to find that other study, sorry.

Exercise is the primary tool tool make the body healthy. In very initial stage we should use exercise. If some one is not satisfied with the result of the exercise then he/she must use the other ways to lose the weight or fitness.

1) wut?
2) you just replied to a post from 2003. You generally shouldn't do this.

Please check post dates before replying.

The most authentic and basic benefits of the exercise is that it is one of the natural and good way to lose the weight but we should not skip any day to do the exercise.

Hell'uva bump.

I looked at my a$$hole in the mirror today; it blew my fukking mind!

[nhclone]

So what would the definition of excersie be in that study? It appears to me that the real conclusion to be drawn is that training for the Armed Froces causes preferential fat loss....you now know the secret people. LOL

(ye I realize that's an old article)

Any comment?

would you please tell me what are the other ways to loss weight as i have no time for exercise. Thank you!!!

Starving usually works, too.
