ilk...and the like, such as over the counter preparations, supplements, etc.
The problem with cutting carbs is that you aren't feeding your brain. Exercise....carbs is what fuels your body to function..like gas in a car.
Now, I'm not meaning chips, chocolate bars, etc. Complex carbs, whole grains, fruit...etc. That's what your body burns. The proteins have a different role, and if you're not getting enough carbs, it'll start consuming fuel from the the protein containing parts. As well, it doesn't really help lower weight because the body goes into a pseudo starvation mode...no food in, no weight loss...conserve energy, etc. That includes thinking.
My take on it...do the research, but you'll have to sift through the buzz stuff first.
Sugar substitutes such as artificial sweeteners, including packaged for coffee/tea, diet drinks, 0-calorie fooRAB, chewing gum, etc....increases your insulin level and with no sugar/carbs to use it up, it's free flowing in your system causing its own problems. Concentration, obesity, mood swings, stress...etc. Since you're only drinking 4 diet pepsies a week, you should consider the regular kind
Your vitamin D levels...most of us are low. My suggestion would be for at least 2000IU D3 daily. I take 4500 IU D3 daily, but mine is low. You should truly get it checked.
Take in enough water...sips regularly are good..that will help preventing you to run to the bathroom often while studying.
A multivitamin with no iron for men is another suggestion.
Read labels....you'll be shocked as to what's in some fooRAB.
I'm not an ingredient zealot by any means...just that there are many choices and the buzz of no carbs/0 calories/artificial sweeteners are making many people unbalanced.
It's great you're enjoying your studies...Biology/chemistry is definitely heavy stuff...
Feel better soon,
