What is fasting?

Fasting is simply not eating, or eating very little, for a set period.
It can be intermittent (like 16 hours fast / 8 hours eat), alternate-day, or periodic (like 5:2 fasting).
It has a positive impact on health if starting from a slight overweight or simply as detox.

Why try fasting?

Fasting isn’t just about weight loss.
It’s a metabolic reset:

Your body switches from using sugar to burning fat
Autophagy (cell repair) kicks in
Helps regulate blood sugar, insulin and inflammation

What does science say?

Heart and metabolic health:
Fasting improves blood pressure, cholesterol, and insulin resistance. Just like caloric restriction.

Weight loss:
A 4:3 fasting plan (fast 3 days/week) led to an average of 7.6% body weight loss vs 5% in daily calorie restriction. Cognitive benefits:
Memory and focus may improve, and fasting may protect against age-related diseases.

Longevity potential:
Early studies suggest anti-aging benefits, including reduced inflammation & improved metabolism.

Who is fasting for?

Anyone wanting weight loss, fat loss
People managing blood sugar or insulin resistance
Those interested in longevity, brain health, and cell protection

Still, fasting is not for everyone:
Pregnant people, those with eating disorders, type 1 diabetes, or certain medical issues should avoid it.
