Had the gastric bypass surgery in 2001, starting weight was 282, lost 100 pounds total in the first 11 months. Maintained for years then after my second child gained and maintained at that weight around 205#. Recently started gaining without reason - same eating proportions and healthy choices, little sugars, etc. even starting working out harder. No change. Dr said for me to take in 1200-1400 calories per day. This site says I should take in 2200. Some ppl think I am not eating enough in a day so my body is storing the fat. There's a big difference in what this site says and what my dr said so I guess we will see what happens! It is so frustrating gaining when I am doing everything right!!
