Why Fasting Backfires for Women

What health problems are you trying to solve?Fatigue? Weight gain? Poor sleep? Mood swings? Brain fog?Educational content reviewed by licensed APRN medical staff. Not personal medical advice.In the video, Dr Vikki Petersen explains why fasting results are different between men and women and what is the optimal approach for women.Time restricted eating or fasting is a physiological stressor - not a bad one, but still a stressor and women react differently to it than men.  Women are not “small men” and our metabolism and hormones are different- therefore the “dose” of fasting matters.A fasting window of 12 to 14 hours allows for adequate protein consumption, better quality sleep, and lowers stress load.Long fasting windows make it harder to hit protein targets - this matters for satiety (stops cravings) and lean muscle mass retention.Protein maintains: Muscle and bone Hormones and enzymes Neurotransmitters - brain chemicals Immune system strengthIf protein intake drops the body breaks down muscle. Lower muscle = more fat, and slower metabolism.Men exhibit more predictable improvements like weight loss and insulin sensitivity while women, who mobilize fuel differently, commonly show weight gain, loss of muscle, insulin resistance, adverse hormone and stress responses.Initially you may not notice negative effects - your fatty acids are elevated meaning you're breaking down stored fat - you lose weight, feel more energy and that convinces you to continue longer fasts.It’s what happens long-term that is concerning - long-term elevation of fatty acids leads to: Reduced glucose uptake into muscle and liver, leading to Insulin resistance - type 2 diabetes, and fatty liver, Greater difficulty losing fat Increased visceral fat/belly weight Muscle breakdown so you lose lean muscle Sleep disruption Brain effects:    Fatigue  Lowered stress tolerance  Brain fog Particularly important if you are in the following categories:FertileIrregular or missed periodsPMS or heavy periodsFeel “wired” but tiredHigh training volumeTrouble sleepingMenopause/PerimenopauseTrouble maintaining muscleFat gain despite eating lessPoor sleepBrain fog or stressCold intolerance of thyroid symptomsFatigue and need caffeineTipsFast while you’re sleeping… and a bit more before and after = 12 to 14 hours.Prioritize protein - aim for 1 gram of protein per lean pound of body weight. Book end protein at the beginning and end of the day with a lighter dose mid-day.Aim for 25 grams of fiber daily from whole food - fruit, veggie, nuts, seeds, beans.Healthy fats come along with much of the foods you’re eatingReferences:Soeters MR et al.
