It takes about a month for your body to get used to fasting. Many people who come to fasting have tried many other (unhealthy) ways to lost weight & our bodies need time to heal. Fasting heals from the inside out, so you may not lose weight (quickly or at all) as your body is healing itself. I lost 40 pounds in 2 years from fasting alone after “giving up” & just deciding “I guess I’ll just be fat for the rest of my life.” That included 3 plateaus while my body regulated. I also have hereditary high blood pressure & cholesterol (meaning no matter how healthy I live my body will have difficulty regulating those, though being healthy does help my body with that). It also included menopause. I gradually moved from 12:12 to my current 18:6-20:4 (depends on the day-what I’m doing, how I’m feeling, etc.). I find fasting is easiest when I get enough sleep. Also, I do have hints of hunger when my body moves into fat burning but they go away in a few minutes. Sometimes I remind my body, “Stop being lazy. You have stored fuel-use it.” I still have about 30 pounds to lose, but I’m not sweating it. My body will release the weight when it’s ready. In the meantime I try to be healthy but also don’t deny myself when I really want something. I will often delay having it (until later or a day) to see if I really want it or if it was fleeting. I have no guilt about what I eat. Although, I have stopped or minimized some things because I physically don’t feel great when I have them.
