I like my bread, my sides, my potatoes, my noodles, my rice, and etc. These are all things with protein. Just not enough to get to 100+ figure.

These are all great carb sources, most meals contain them for that reason, not for their protein. Their protein is really negligible. Let's take a look,

  • baked potatoes ~ 1.7g protein in 100g (1.7%)
  • Rice ~ 7.5g protein in 100g. (7.5%)
  • Bread, I assume common bread based on wheat flour, so roughly 12g of protein per 100g. (12%) This one is not exactly negligible, but it has almost as high carb content (~75g) as rice (~80g).
  • Noodles, depends on what they are made of. Wheat flour or rice, you can see the previous bullets.

So what you say makes sense. If you try to get all your protein mostly from such sources, you will load a great deal of carbohydrates, almost certainly more than you need, even as a very active athlete. Regardless of what path you choose though, even without chicken breasts, there are foods with great concentrations of protein.

And I think you are overestimating the amount of protein you need. 100+ figure is fine, but really not necessary, anything close to 80 for the weight you mentioned, especially in a fairly inactive person, should be pretty much fine. Especially if you have days every once in a while that you go well above 100g.

Carbs tho, regardless of size or calories, once you load all your glycogen (which is what carbs are converted to if you are not already full) stores in the muscle tissue and liver, if you are inactive, will become triglycerides (fat). And an average person doesn't store too much glycogen either, you can estimate it around 500g to get a sense of how excessive carbs can make us both fat and, eventually, sick. One important reason why complete inactivity (especially in the big muscles groups, take a walk, run, lift, jump, dance -use your legs!), makes us fat fast.

.75-.8g/lb is likely the upper limit for humans in terms of necessity and lower values are likely fine for most individuals. 50g/day is perhaps on the low side, but not unreasonable for a 2000kcal/day person who's not trying to gain muscle. With that being said, having more protein in the diet is almost never a bad thing (it's pretty much impossible to hit a problematic level without seriously supplementing) whereas excessive fat or carbs are much more likely to cause problems.

This was a very nice article, both an enjoyable read and informative. Kept the study about endurance athletes on a deficit for later, since I recently went about losing a few kg in exactly the manner they tested.

50g/day is perhaps on the low side, but not unreasonable for a 2000kcal/day person who’s not trying to gain muscle.

Thanks for pointing that out. Yes, I don't think its unreasonable either, but haven't even actually tested it on myself.
