Want to try fasting but not sure where to begin? Fasting can help with weight, focus, and gut health when done right. This guide gives simple methods, quick steps to start, and safety tips — including how to handle prescriptions while fasting.
Time-restricted eating (16:8) — eat during an 8-hour window, fast 16 hours. Most people skip breakfast and eat noon to 8pm. It’s easy to try and fits many schedules.
5:2 — eat normally five days, then eat 500–600 calories on two nonconsecutive days. Good if you want fewer daily rules but still want calorie control.
Alternate-day fasting — fast every other day or eat very little every second day. Faster results for some, but harder to stick with.
24-hour fasts — done weekly or monthly. Shorter-term and more intense; best for experienced fasters.
Pick one method and try it for two weeks. Start with 12:12 (12 hours fasting, 12 hours eating) if you’re new, then move to 16:8 when it feels easy. Keep meals simple and protein-focused during eating windows: lean protein, veggies, whole grains, and healthy fats.
Stay hydrated. Drink water, black coffee, or tea during fasts. If you get headaches or dizzy, add electrolytes or a pinch of salt.
Avoid bingeing when your window opens. Have a balanced meal ready so you don’t overdo sugar or junk food.
Use mindfulness to manage hunger. Slow breathing, a short walk, or chewing sugar-free gum can stop a hunger wave before it escalates.
Track sleep and energy. If sleep suffers or you feel weak, ease up on fasting length or change the timing. Fasting works better when stress is low and sleep is solid.
Medication and medical safety — don’t guess here. If you take insulin, sulfonylureas, blood pressure meds, or psychiatric meds, talk to your provider before starting. Some drugs need food to avoid low blood sugar or stomach upset. Your TRICARE plan and pharmacists can help adjust doses or timing.
Who should avoid fasting: pregnant or breastfeeding people, children, people with active eating disorders, or anyone with unstable diabetes or recent surgery. If you have chronic conditions, check with your provider first.
Common problems and fixes: feeling cold — layer up and move more; bad breath — chew sugar-free gum or rinse; constipation — eat more fiber during eating windows and hydrate. If you faint, stop fasting and seek care.
