STUDY:
Nice. From 1983. Mew, what does it say about changes in estrogen?
Also, a somewhat unrelated question, do you know if T levels, both total and free, can be tested accurately through urine? Because I would suppose this would be cheaper, if this were the case??
Sorry but thats BS.
Desperado.
Interesting to note people feel worse on high carb diet.
I feel the same no matter what i eat.
False.
We could probably list a lot of positive and negative things for both carb and protein rich diets. I generally feel better on higher protein diets and definitely felt worse on too sugary diets even before PFS.
BTW, just to mention a few positive things for protein rich diet:
- Can decrease SHBG that may be good for some around here. (peaktestosterone.com/high_shbg.aspx)
- High protein diet helps you lose weigh and also to build muscle if that is your goal.
I’ve just tried an extremely high protein and low carb diet in the last 2 weeks and it felt really good. The speed of muscle building ability of a high protein diet is wonderful. Some fitness sites suggest that even without serious trainings a high protein diet helps a lot in losing weigh if that is your goal.
Hey guys,
I just want to respectfully explain that this study definitely DOES NOT say that “Carb-rich diet increases Testosterone vs Protein-rich diet.”
Actually what the study says is that on the high protein diet:
- less testosterone was metabolised by the 5ar enzyme in the liver (I think converted into DHT but my molecular biology is not advanced enough to say)
- more estradiol was metabolised by the CYP450 enzymes in the liver
This does not actually suggest anything:
- about total or free testosterone levels on protein rich diets vs carb diets
- about estradiol levels on protein or carb based diets
- about the conversion of testosterone or estradiol in places other than the liver.
It’s a really nitty gritty study about a very specific metabolic pathway, not about total hormonal changes form diets.
I want to advise people that for me, I brought my testosterone up from 450 ng/dL to 932 ng/dL using a diet low in refined carbohydrates among other things.
If anyone has a different perspective or wants more info about the dietary stuff I’ve been researching, let me know.
Interesting. Carbs always seem to make me feel better, which I thought was weird since everyone here is all about avoiding them like they are the plague. However, I can’t say that any change in eating habit has had an effect on this. When I eat carbs though my anxiety decreases substantially.
While my experience doesn’t suggest carbs are a universal good or anything (too many and eating them at the wrong time of day and what not), I can say with confidence that an increase in carb intake has had a positive impact on my mood and muscle mass. Be a heck of a coincidence if there wasn’t a causal link. I recently switched to the SCD (specific carb diet), as I think non-SCD carbs are bad for my gut. Regardless, I’ve been gaining muscle by the day without training for the past 45 days or so and carbs have very likely been playing a big role in that. As an aside, sugar seems to be very bad, whatever the reason. I am eating a zero sugar, high carb, high protein, and very low fat diet.
How can you eat zero sugar on a high carb diet?
Grains are about 70/80% sugar. All Grains Make Your Blood Sugar Spike.
Legumes are high carb, low sugar and a blood sugar friendly food. Yeah it’s not ‘zero’ sugar, I’m not sure why I put that, but it’s very low sugar. Not eating any grains anymore. Diet consists strictly of tilapia, cod, turkey, tons of legumes, and greens, supplementing with calcium/D and E.
Legumes are 40/50% sugar (amids), they also contain phytic acid and many other antinutrients.
40-50% sugar? That’s nonsense. A full serving of lentils contains no sugar. I am not sure what you mean by ‘amids’, however, so I don’t even understand your point to begin with. Maybe I am misunderstanding something. As to your other point, I just don’t buy the paleo perspective, either in general or for my particular case of PFS (each case is different obviously), as it’s clear to me that the noticeable muscle tightening/expansion I’ve experienced lately is attributable to carbs.
