I think that low carb effectiveness will decrease over time because the body builds a tolerance to the approach. Heck, if you’ve been doing low carb for five years then try to go even lower carb, you are not going to get the same effect that you would if you went low carb coming from a diet of cookies, coke and pizza.
I am also beginning to think that hormonal balance has something to do with it, and as we age, some of these hormones decrease (thyroid and testosterone are 2 I’m considering more research on) and this will make low carb less effective over the long run.
I’ve learned a lot from the people posting on the Irvingia Field Reports – even if you are not interested in the supplement, there’s plenty of other interesting stuff surrounding the challenge of weight loss that might be of help.
Younger folks just starting out on low carb have the best chance of dramatic weight loss. This happened to me in my early 40s – it’s my mid-40s where I’m not seeing the same result. I think this means that – if you succeed in losing weight low carb, NEVER LET IT COME BACK! Don’t think that if you let your weight creep up, you’ll be able to lose it as easily next time – it will be incrementally harder the next time.
And you will probably find that as time goes on, even if you don’t let it creep back, and keep the same habits, the weight will begin to increase anyway as you age and your body becomes more finely tuned to low carb. Let’s face it – all of us here are swimming upstream – we’re meant to be fat – it is the state our bodies want to be in. When you disagree with your body, expect it to fight you all the way.
My hypothesis is that, once we’ve trashed our bodies on high-carb crap for 20 years, it is impossible to totally recover from this. Like smokers who quit, you can reverse a lot of the damage, but not all. So you can never be totally like a true paleo – he never ate a bag of Cheeze Doodles while watching Australian Rules Football.
(By the way – I don’t like sports – but I LOVE Australian Rules Football. They used to show it in the US years ago – I was addicted. American football players are wimps compared to these guys.)
So – is it hopeless? Of course not. What it might mean is that you have to change your tactics as time goes on, while you stick to the same strategy.
