For me personally - a significant difference. My productivity has increased due to rarely incurring cognitive fatigue due to fluctuating energy levels (i.e that afternoon slump after lunch goes away, skipping a meal has little or no consequence). I can code for 8 straight hours without having to eat where before if I skipped a meal I'd start getting hazy. Additional benefits include weight loss while eating as much as you want, never getting hungry, being able to do a 10km run on an empty stomach and still be full of energy ..
