What is ketosis?

A metabolic state where your body lacks glucose from carbs and instead burns fat, producing molecules called ketones for energy.

Is the Keto diet safe long-term?

Strict keto is hard to sustain and can lead to nutrient deficiencies and elevated LDL cholesterol, so it is best used under medical supervision.

Can I drink coffee while fasting?

Yes, black coffee (without sugar, milk, or creamer) has zero calories and does not break your intermittent fasting window.

What is the keto flu?

A temporary group of symptoms (headaches, fatigue, nausea) that occurs as the body adjusts to cutting out carbohydrates.

What is autophagy?

A natural process triggered during fasting where your body cleans out damaged cells and regenerates new, healthy ones.

Do diets fail because of slow metabolism?

Rarely. Most diets fail because they are too restrictive, causing people to binge and break their calorie deficit limits.

Is it mandatory to skip breakfast in intermittent fasting?

No. You can choose any 8-hour window, such as 8 AM to 4 PM (eating breakfast and lunch) and skipping late dinner.

Can I build muscle while doing intermittent fasting?
