Due to the cancer, both my Naturopath and my Oncologist say I can’t do estrogen therapy, but only testosterone. I have been researching the topic from different weight gain is unacceptable to me. My sister had a hysterectomy last year and gained alot of weight in her abdomen, hips, and butt. She was always tiny. My next step is to get bloodwork done to check my thyroid, hormone levels, etc. I will continue to battle this bulge, as I am determined NOT to get fat, but to get my lean abs and small waistline back. Research shows that determination is the one crucial factor in achieving success in life. So just call me “Determined”. ☺
Don’t give up on yourselves.

If you want to gain weight healthily, the quickest method is by changing your eating habits. For a woman trying to lose a pound per week, she should try to eat 500 calories less than burned on a daily basis. When you are trying to gain weight, this process should be reversed. The easiest way this can be achieved is by consuming your normal healthy meal plan along with protein shakes, but with the addition of other meal replacement drinks. Typically, meal replacement drinks are consumed in place of a meal, and they contain a moderate amount of calories, protein, and carbs.
