“Estrogen is formed in fat cells under the influence of cortisol, and this formation is suppressed by progesterone and thyroid. Postmenopausal obesity is associated with increased estrogen and breast cancer. The prevention of weight gain, and supplementation with thyroid and progesterone if necessary, should be protective against many types of cancer, especially breast, kidney, and uterine cancer.” Raymond Peat, PhD
The heavier you are, the more estrogen your body is producing, the more estrogen dominant you become the harder it is to lose fat.
Therefore, you have to decrease anything that is estrogenic in the diet and in your environment. You also need a diet that will rid you of excess estrogen…adequate protein, organic dairy, one raw carrot daily, and avoid PUFA’s.
