I find it very frustrating when I read tips like "have you tried to lower your calories/increase your exercise?" After weight loss surgery you are WELL below the caloric limit recommended by nutrition specialists. You should be exercising your body in some way as most doctors require an exercise routine pre-op.
The human body does not always work like clockwork and the calories in>calories burned equation does not always work consistently for everyone. There are hormones at work, especially in a female body, that regulate Fluid retention and metabolism. I have found almost 4 months post-surgery that I always, like clockwork, stall as I am leading up to ovulation. I will have a week to 10 days (this time, sadly, it has been 15 days) where, even though I am eating under 1000 calories a day and working out 30 min, 3-times a week, that the scale WILL NOT BUDGE. That gives me only 2 to 3 weeks a month of optimal weight loss. The week I ovulate I am just NOT gonna lose anythingl.
I hate it and I get discouraged and I cut my carbohydrates and up my Protein and drink more Water in a feeble attempt to get the scale to move, but it just won't. Not until my endocrine system is ready to let it go... I am a victim of this hormone cycle. The only thing to do is ride it out and know it happens to everyone.
Even if I never lost another pound, the 61 pounds I have lost since I started this journey have been enough for me to say it was totally worth it, stalls and all.
