Intermittent fasting: what actually works
Intermittent fasting compresses your eating into a window, most commonly 16 hours fasted and 8 hours fed. It works, but mostly for an unglamorous reason: fewer eating hours usually means fewer calories. Understanding that makes you far more likely to succeed with it.
What fasting does and does not do
In controlled studies, fasting produces similar fat loss to regular calorie restriction when calories are matched. Its power is practical: many people find one big rule, do not eat before noon, easier to follow than counting every meal.
Claims beyond weight, like dramatic longevity effects in humans, remain unproven. Blood sugar control often improves, but largely because weight drops and late-night eating stops.
Who tends to do well, and who should skip it
Fasting suits people who naturally skip breakfast, prefer fewer larger meals, and want simple rules. It also pairs well with a busy morning schedule.
It is a poor fit if you train hard early in the day, struggle to eat enough protein in a short window, have a history of disordered eating, or are pregnant. Athletes with two sessions a day usually need the wider window.
How to start without wrecking your protein
Begin with 12 hours and extend gradually toward 16:8. Keep protein high inside the window, roughly 1.6 to 2.2 g per kilogram of body weight, split across two or three meals so muscle is protected.
Calories still decide the outcome, so know your target from the calorie calculator. Equil makes the window practical: scan your meals by photo, watch protein and calories fill up in real time, and see whether your eating window actually delivers what your training needs.
Stop tracking by hand
Equil reads your food, glucose, sleep and training, then adjusts your plan in real time. Not another logger, a coach.
