lowering of metabolism after weight loss

But it's not. It's more about how our bodies are. Just like running.
You'll never be as fast as person with a lot of fast twitch muscle fibres.
Clearly to be a world class athelete requires an immense amount of work
and steroids, but it's difficult to overcome your genetic heritage.

If you are born with fewer dopamine receptors you are much more likely to
be an addict and/or overweight. Plus a dozen other hormone interactions
that are genetic. Plus the instinct to eat in our fat/sugar environment.
Plus we don't need to exercise to survive anymore.

To say it's all about mindset is to not really understand what's going on.


The problem with that mind set is it allows any bad or negative
behavior.....When I explain to my wife that my sleeping around can't be
helped because of the "gifts" I'm blessed with I'm sure I'll find great
comfort living elsewhere.....Try telling your boss that will be chronically
late because your such a heavy sleeper and can't always get
up......discipline and adaptation(several loud alarm clocks) to the problem
is both needed and required for most successful lives...everybody indeed may
have different battles, temptations or desires as we all struggle with
different things.....but everybody is more than capable.....The trick with
food is not particularly in the doing (eat less or eat differently) but in
the wanting to day after day after day......not confusing wishes with wants
helps as well. I may wish I was thinner but if I don't or won't do something
about it I do not actually want it.....One may surmise that wishes and
fairytales come true rarely just like successful diets...however everybody
whom "wants to" will. (except for maybe a few medical oddities).... Rod

Their thyroid glands didn't change. If the only reason they lost weight was
less calories, then they didn't build muscle. You have to exercise to be
healthy and build muscle.

A while ago there was some discussion on if the body adjusts metabolism
after weight loss to maintain the higher weight. Here's an article that
talks about the issue:

Why lost weight returns after dieting
http://www.news-medical.net/?id=2955

The data suggests that weight loss in obese, obesity-prone rats, induced
by caloric restriction, is accompanied by metabolic adaptations that
predispose one to regain the lost weight. In rats that are losing weight,
this is exhibited by a significant reduction in metabolic rate, measured
as both 24-hour energy expenditure and sleeping metabolic rate, both
independent of metabolic mass and energy intake. This adaptation persists
after eight weeks of intake-regulated weight maintenance, but is no longer
present with eight subsequent weeks of feeding at-will where rats are
regaining lost weight. While rats that are regaining weight may have a
shift in appetite that would contribute to their high rate of weight
regain, the drive to increase food intake remains the most critical factor
in the predisposition to regain lost weight. This adjustment clearly
weighs more on the energy balance equation than the metabolic adjustment
on energy expenditure observed in this or any other study.

Additionally, the effect that energy intake, or more particularly,
carbohydrate intake, has on respiratory quotient [dividing the amount of
CO2 produced (VCO2) by the amount of oxygen uptake (VO2)]. RQ is much more
dramatic than the metabolic adjustment observed from weight reduction.
This drive to increase food intake likely involves environmental stimuli
(diet composition, food palatability, physical activity) influencing
motivational and metabolic components of a genetically determined set of
central systems.

While the data suggest that these metabolic adaptations might hinder
successful weight maintenance, it should not imply that successful weight
maintenance is unachievable. Even with the increased intake of
carbohydrates, regular physical exercise may be the key factor that
counteracts these metabolic adaptations to weight loss.

I notice that after everyone of these pronouncements saying how hard
weight is to lose they say something like it's not unachievable. How hard
does something have to be before people stop trying to achieve it?
Not very hard.

for me its the only way to do it.

That's been my perception. I kind of feel like my metabolism is
faster now than it was when I was heavy. Maybe not in absolute terms
-- I eat less now than I did then -- but relative to my bodyweight I
eat more, I think. I attribute this to the fact that I exercise a
fair bit.

So if you want it bad enough you can be a four minute miler? I think
not. Your physical body establishes what is ultimately possible.

Numerous people lose weight
and keep it off, not without difficulties. It is not impossible.

Nor is it easy enough to expect even the majority of people to be able
to do it.

The 2PD-OMER Approach is simple enough.

I believe that is because they have encountered some of the more than
625,550 people who have achieved lasting ( 5 yrs) weight loss using the
2PD-OMER Approach.

Not everyone is able to run a 4-minute mile - it's not physically
possible.

Rubish. It's just mind over matter. Just eat less exercise more. Wait,
that's for weight.

But, it is physically possible for anyone to consume a few less calories
than they burn each day.

And you know this how? As we are just learning about most of these
mechanisms and we are only a generation or two into the world of plenty
without exercise- there's no way for you to know. All evidence is going
the other way. Many yogis can control their breathing so they can stay
in a coffin for days. It's possible. Can the other 99.999956% of
humanity? Unlikely.

So, we should all just give up then? Look for help through drugs and
surgery?

No.

But, it is physically possible for anyone to consume a few less calories
than they burn each day. It can be challenging, because of they availability
of food, and the way it is consumed recreationally and socially.

Is it easy to lose weight? No.

Is it possible? Yes.

Here's how:

Any fat person can lose weight if they are calorie restricted (for
example, confined in a cage with limited food). It is unlike running.

That's not really the point though. What is important is how do you keep
the weight off when you are free in the wild.

Surely, we know that the majority of people cannot lose weight, and
the majority of those who can lose weight does not keep it off. So,
here, I agree with you.

I don't know about cannot, but it's a lot harder than people want to admit.

Not for those learn to watch **how much** they are eating and choose to
befriend the **healthier** appetite that comes from eating less down to
the **right** amount.
