I can't eat enough

What are you eating? And do you do any walking? Other physical activities?

I always said if I kept track, I was not even eating 1000 calories a day! ok, so how did I get so big if I eat below that some days.....laziness. So now that I am up with all the energy I still find I am some days only intaking 600 a day, feeling pretty good, not hungry, energetic, but I know I can't lose any weight at this rate. Any feed back on this

What happens is our bodies adjust to the lower caloric intake - we lose lean body mass, mess up our hormones and slow our metabolism. The result? Weight gain because our caloric needs get so low...so, gradually increase your calories to a reasonable deficit from your TDEE (many threads about this), stay off the scale in between (we have a tendency to gain when we reset our food levels, but it is temporary), and maintain the new caloric amount for 4-6 weeks at least. Also, add weight training to maintain and maybe gain (at first) a little lean body mass to help increase your metabolism. (NROLFW is a great start with lost of info, science to back it up, and workout troutines for 6 months). For example, I am 5'2" tall, 42 years old and moderately active (3 weight training sessions per week) and I eat 2000 calories per day for about a third of a pound loss each week (I only have 8 pounds to go)
