CR goal beats exercise goal?

[Guest guest]

Hi All,

The below is pdf-available.

Of possible note, were the excerpts:

" ... dieting rules 'reducing calories' and 'increasing exercise' ...

Interestingly,

dieters who used both rules in combination were less likely to reach their

dieting

goal than those who only used one of them. Follow-up analyses showed

specifically

that dieters who just used caloric reduction as a rule for losing weight were

more

successful in losing weight than dieters who used both rules. "

Self-set dieting rules: Adherence and prediction of weight loss success.

Appetite. 2005 Jun;44(3):283-8.

.... the weight loss goal that dieters set for themselves was associated with

their

BMI (r=0.59, p<0.0001), with a higher BMI being associated with the intention to

lose more weight, BMI was controlled for in all regression analyses.

Type of rule

Multiple regression was used to test which weight loss rules predict dieting

success. For the first model a score was created for each category that

summarizes

how many rules an individual had reported within each category. The interaction

between exercising (Category III) and reduction of calories (Category I) was

also

included in the model to test how well engaging in both type of rules. In this

sample, 79.5% of dieters reported using both type of rules at T1. As can be seen

in

Table 2, the more individuals reported rules relating to exercising or to

reducing

calories the more likely they were to reach their weight loss goal.

Table 2. Results of multiple regression analysis predicting dieting success by

type

of rules used

---------------------

Dieting rule B S.E. t P

-----------------------

Reducing calories 19.59 7.25 2.70 .008

Changing what one eats -4.43 5.06 -0.88 .38

Increasing exercise 26.78 12.39 2.16 .03

Changing attitudes 0.06 4.38 0.01 .99

Changing eating habits 7.06 5.72 1.23 .22

Combination reducing calories/exercise -13.79 5.19 -2.66 .009

Interestingly, dieters who used both rules in combination were less likely to

reach

their dieting goal than those who only used one of them. Follow-up analyses

showed

specifically that dieters who just used caloric reduction as a rule for losing

weight were more successful in losing weight than dieters who used both rules.

They

came more than twice as close to reaching their dieting goal than dieters who

used

both rules (M=39.7%, SD=68.6%, vs. M=14.5%, SD=51.7%). Expressed in absolute

amount

of weight loss, those who just used caloric reduction as a rule lost 1.51 kg

while

those who used both rules lost 0.81 kg. This difference is not statistically

significant (t(115)=1.67, p<0.095, for amount weight loss achieved), but the

difference in mean values warrants further analysis, which will be reported in

the

next paragraph.

Adherence to dieting rules

It was tested how adherence to dieting rules predicts dieting success. Following

the

same structure of analyses as for the type of rules, a score was created for

each

category that summarizes how many rules an individual had reported within each

category at both T1 and T2. The interaction between the consistency of reporting

reduction of calorie rules (Category I) and consistency of reporting exercise

rules

(Category III) was also included in the model. Table 3 reports the results of

this

analysis. As can be seen, the consistency of reporting caloric reduction and the

consistency of reporting exercising predicted weight loss success (with

exercising

approaching significance). The more consistently individuals reported rules

relating

to exercising or to calorie reduction the closer they came to their weight loss

goal.

Table 3. Results of multiple regression analysis predicting dieting success by

degree of adherence to rules

--------------------

Dieting rule B S.E. T P

---------------------

Reducing calories 14.66 6.69 2.19 .03

Changing what one eats -4.57 5.20 -0.88 .38

Increasing exercise 31.27 17.09 1.83 .07

Changing attitudes -1.85 10.23 -0.18 .86

Changing eating habits -1.82 10.85 -0.17 .87

Combination reducing calories/exercise -40.52 15.86 -2.55 .01

Similarly to the prediction of dieting success by type of rule, adhering to both

exercising and reducing calories resulted in lower dieting success than adhering

to

only one of the strategies (see Table 3). One could speculate that dieters who

solely relied on caloric reduction were more successful because they had more

weight

to lose: Specifically, these dieters weighed more at T1 than those who used both

rules (M=68.90 kg, SD=16.30, vs. M=62.52, SD=10.44, t(118)=2.05, p<0.04) and had

a

higher BMI (M=25.04, SD=5.92, vs. M=22.67, SD=3.26, t(117)=2.33, p<02).

Participants

who used just exercising as a weight loss rule did not differ from those who

used

both rules in terms of their dieting success, initial weight, and BMI (all

>0.05).

Hi Al:

Makes perfect sense. Unless the individual is running marathins

(looks like a freudian typo, LOL, so I left it in!) daily exercise

will never be the major contributor to weight loss.

So telling people to exercise as well as reduce caloric intake

dilutes the message they really need to take to heart.

Someone once told me they had a serious weight loss plan and were

walking a mile every evening!

They never lost any weight.

While I don't see what this has to do with CR, regular exercise seems to be

useful for healthy aging.

Interesting news reports about Euro kids with type II diabetes etc. This human

animal will eat itself to death at an early age if allowed to. I doubt

the problem is isolated to the continent. But alas this doesn't

have anything to do with CR either, other than an obvious statement

that it's our nature to eat everything we can.
