Thanks for all the responses. After observing my weight for the past 7 months, I'm pretty sure I was in starvation mode since I lost about 15 pounds in the period I was dieting and am currently back at the same weight before the diet.
I developed acid reflux at around the same time. Could malnutrition/not eating enough/eating only fruits cause reflux? Ahhh, I really screwed myself over. I'll try to get one of those Resting Metabolic Rate tests done - thanks for that very helpful piece of information!
