Intermittent Fasting: Benefits, Risks and Expert Opinions
Intermittent fasting is like having set times to eat and not eat each day.
Some people eat all their meals within a specific window, like 8 or 10 hours, and fast for the rest of the day.
It can help with losing weight by letting your body burn stored fat.
Experts say it can be helpful, but it's not for everyone.
Some people might feel tired or have headaches.
Also, it's essential to eat healthy foods during your eating times.
It is also very important to speak to your doctor before trying it.
Intermittent fasting involves cycling between periods of eating and fasting to manage calorie intake.
Research suggests intermittent fasting can aid weight loss, reduce body fat, and improve health markers.
Time-restricted eating (TRE), a form of intermittent fasting, involves eating within a consistent window daily.
Potential benefits include improved insulin sensitivity, reduced inflammation, and cellular repair.
Experts highlight that individuals should consult healthcare professionals before starting intermittent fasting.
