Just out of interest, have you had any tiredness from cutting carbs from your diet? Many people on who restrict carbs, such as on the Atkins diet, experience this from what I've read.
Veggies)
Bad:
-I typically felt kinda "blah", like I was on the verge of getting a cold
-generally low on energy
-injuries took forever to heal
-my joints ached after being on the diet for about 6 months
-I felt hungry almost immediately after eating
-I lost much less weight than on Atkins
Good:
-It's hard to describe, but I felt "clean" all the time. Like I had just taken a shower.
-I also tended to feel light, like moving about took less energy, but I felt like I had less energy overall
Atkins)
Bad:
-I felt kinda "gross" all the time, like oil was oozing from my pores and follicles.
-Expensive
-Most of the foods I wanted to eat were not on the approved list, and I got tired of eating on the diet after about 6 months
-I felt hungry all the time
-Hair and nails grew really fast...like freakishly so. I was cutting my finger nails like every 2 days at one point.
-I felt "heavy"
Good:
-I had super, non-stop, bottomless energy
-no midday loss of energy
-I could exercise for hours
-I lost tons more weight than on the veggie diet (about 3x as much in the same amount of time)
-Injuries healed super fast, maybe twice as fast as normal, and I got injured far less often than on the veggie diet, maybe 1:3 ratio
-I felt stronger, so even if I felt heavier, it was less effort to move about
-I packed on muscle, my bench press (without actually doing any weight lifting as a form of exercise) went from 140 to 210 in 6 months.
As far as my energy levels nowadays...pretty much boundless. I'm ravenously hungry when I don't eat. But I'm told that's how it's supposed to work. When I was fat, I was hungry around the clock, even after eating.
