Why isn't there like a pinned sticky about the science behind losing weight ?

Should I make one ?


It would curb the amount of "HOw do I lose weight" threads.

losing weight is not big deal, maintain the weight after you losing it is something serious. I am on the process of losing weight now, build up the awareness of healthy lifestyle and selective eating but those delicious are just too tempting. biggrin.gif

5 spoons? how many cups is that? hmm.gif imho, instead of 3 meals. split it into 5-6 meals in order to keep your metabolism rate high. protein intake too less as well. cheers

well, apparently the myth works for me. i dropped my BF% from 24 to 18 in 5 weeks and maintaining my muscle mass with high reps workout program. if you have time and commitment, no harm trying it out right? blush.gif

I dont think one could called it a myth, studies has shown its inconclusive. we should not be concluding anything just based on a one or two studies. A new study would show otherwise.

Regular (consistent) Split meals has its benefits in many ways.

Inconclusive? One or two studies? There has been more than 10 done iirc, and they were all pretty much conclusive, that frequent feedings have no effect on metabolism compared to fewer feedings.. The fact that its been replicated so many times means its very conclusive.

Perhaps there are other benefits, but there is no metabolic advantage to it.

Link to said study please. Does it assert that there is metabolic advantage to frequent feedings? Otherwise, skip it.

honestly i've tried both.....many meals and 3 meals per day, i dont see much changes in my metabolism as well as my weight.....DL do it with only 3 meals and now i'm on 3 meals most of the day as well....still okay with my weight and all....so yea, i'm with darkseifer this time smile.gif

somewhat I agreed with you but not as whole....when looking from a holistic view, it has more benefits to split the meals, hence that practice should not be discarded in a fly.

Eating 3 meals is fine, if you know what you are doing, and have planned your micros/marcos.

sorry, I'm unable to detail my thoughts further....short of time...hence copy and paste reading material below...

<<
Meal frequency was related to BMI and should be considered when developing guidelines to prevent childhood overweight.

http://www.nature.com/ijo/journal/v32/n1/abs/0803654a.html
>>

<<
Eating meals regularly is inversely associated to the metabolic syndrome, insulin resistance and (high) serum concentrations of gamma-glutamyl transferase. These findings suggest that eating meals irregularly may be part of several potential environmental risk factors that are associated with the metabolic syndrome and may have future implications in giving dietary advice to prevent and/or treat the syndrome.

<<
The prevalence of obesity decreased by number of daily meals: three or fewer meals, 4.2% [95% confidence interval (CI), 2.8 to 6.1]; four meals, 2.8% (95% CI, 2.1 to 3.7); and 5 or more meals, 1.7% (95% CI, 1.2 to 2.4). These effects could not be explained by confounding due to a wide range of constitutional, sociodemographic, and lifestyle factors. The adjusted odds ratios for obesity were 0.73 (95% CI, 0.44 to 1.21) for four meals and 0.51 (95% CI, 0.29 to 0.89) for five or more meals. Additional analyses pointed to a higher energy intake in nibblers compared with gorgers.

Results: Omitting a meal was followed by increases in fat mass (360 plusminus 115 grams, p < 0.05), late evening leptin concentration (20.7 plusminus 11.0% , p < 0.05), and respiratory quotient (3.7 plusminus 1.4% , p < 0.05). Increase in the percentage of dietary fat during the habituation period (+4.1 plusminus 2.0% , p < 0.05) was correlated with fat mass (r = 0.66, p < 0.05). Adding a meal had no effect, but, in both groups, the change in energy content at this fourth eating occasion was correlated with the change in adiposity.

Discussion: Our results suggest that adiposity may increase when young lean male subjects switch from a four- to a three-meal pattern by removing their usual afternoon meal. This effect could be partly mediated by a change in the macronutrient composition of the diet.

<<
The irregular meal frequency appears to produce a degree of insulin resistance and higher fasting lipid profiles, which may indicate a deleterious effect on these cardiovascular risk factors.

http://www.ncbi.nlm.nih.gov/pubmed/15220950
>>

<<
The data indicate that increased meal frequency may have a beneficial effect on a reduced BMI. Physical activity and breakfast skipping may be candidate targets for prevention programmes aimed at reducing overweight/obesity among adolescents

http://www.ncbi.nlm.nih.gov/pubmed/18274921
>>


Clearly the above shows that there is a link of meal frequency and metabolism, muscle mass, obesity and fat loss, insulin resistance.

Hence we should not brush aside meal frequency and metabolism or the other body's characteristic changes to the affect.

And clearly I dont want to pick a fight, just matter of discussion, and hope others could throw some factual light as well.

Cheers.

You did not present a cohesive argument. I would advice you not to straw man my position and stay on topic. Nobody said that frequent feedings is useless. Did you not properly read my original response? The previous poster recommended to split meals to keep metabolism high. Frequent feedings to increase metabolism is a myth. I did not say anything else.

The assertion: Does meal frequency increase metabolism?

The answer is no. Its that simple. Controlled trials have demonstrated that clearly.

http://www.ncbi.nlm.nih.gov/pubmed/1905998
QUOTE
A study was conducted to investigate whether there is a diurnal pattern of nutrient utilization in man and how this is affected by meal frequency to explain possible consequences of meal frequency for body weight regulation. When the daily energy intake is consumed in a small number of large meals, there is an increased chance to become overweight, possibly by an elevated lipogenesis (fat synthesis and accumulation) or storage of energy after the meal. Thirteen subjects, two males and eleven females, were fed to energy balance in two meals per day (gorging pattern) and seven meals per day (nibbling pattern) over 2-day intervals. On the second day on each feeding regimen, the diurnal pattern of nutrient utilization was calculated from simultaneous measurements of oxygen consumption, carbon dioxide production and urinary nitrogen excretion over 3 h intervals in a respiration chamber. A gorging pattern of energy intake resulted in a stronger diurnal periodicity of nutrient utilization, compared to a nibbling pattern. However, there were no consequences for the total 24 h energy expenditure (24 h EE) of the two feeding patterns (5.57 +/- 0.16 kJ/min for the gorging pattern; 5.44 +/- 0.18 kJ/min for the nibbling pattern). Concerning the periodicity of nutrient utilization, protein oxidation during the day did not change between the two feeding patterns. In the gorging pattern, carbohydrate oxidation was significantly elevated during the interval following the first meal (ie from 1200 h to 1500 h, P less than 0.01) and the second meal (ie from 1800 h to 2100 h, P less than 0.05). The decreased rate of carbohydrate oxidation observed during the fasting period (from rising in the morning until the first meal at 1200 h), was compensated by an increased fat oxidation from 0900 to 1200 h to cover energy needs. In the nibbling pattern, carbohydrate and fat oxidation remained relatively constant during the active hours of the day.(ABSTRACT TRUNCATED AT 250 WORDS)


http://www.ncbi.nlm.nih.gov/pubmed/9155494
QUOTE
Several epidemiological studies have observed an inverse relationship between people's habitual frequency of eating and body weight, leading to the suggestion that a 'nibbling' meal pattern may help in the avoidance of obesity. A review of all pertinent studies shows that, although many fail to find any significant relationship, the relationship is consistently inverse in those that do observe a relationship. However, this finding is highly vulnerable to the probable confounding effects of post hoc changes in dietary patterns as a consequence of weight gain and to dietary under-reporting which undoubtedly invalidates some of the studies. We conclude that the epidemiological evidence is at best very weak, and almost certainly represents an artefact. A detailed review of the possible mechanistic explanations for a metabolic advantage of nibbling meal patterns failed to reveal significant benefits in respect of energy expenditure. Although some short-term studies suggest that the thermic effect of feeding is higher when an isoenergetic test load is divided into multiple small meals, other studies refute this, and most are neutral. More importantly, studies using whole-body calorimetry and doubly-labelled water to assess total 24 h energy expenditure find no difference between nibbling and gorging. Finally, with the exception of a single study, there is no evidence that weight loss on hypoenergetic regimens is altered by meal frequency. We conclude that any effects of meal pattern on the regulation of body weight are likely to be mediated through effects on the food intake side of the energy balance equation.


Thus adding more meals while keeping total calorie intake the same does nothing to improve metabolism. You posted nothing to refute that. By the way, correlation does not imply causation, keep in mind the next time you decide to draw conclusions from behavioural/statistical studies.

Tried the 5-6 meal method. No difference for me in terms of result. It just felt more irritating. Broscience sux. Lol.
