The natural appetite suppressant properties of black coffee also help curb snacking, especially if consumed in the morning. Black coffee also boosts energy levels, making it a useful pre-workout drink, helping to boost endurance and aid in fat burning.
Dr. Manjusha Agarwal, senior consultant in internal medicine at Gleneagles Hospital, Mumbai (India), said: Since black coffee (without sugar) has no calories, it becomes a weight loss-friendly drink. The low-calorie nature and metabolism-boosting effect of black coffee make it useful in fighting obesity, according to Hindustan Times.

What happens to your body when you drink black coffee in the morning?
Thermogenesis : Black coffee stimulates thermogenesis, increases metabolism, helping the body burn calories and excess fat more effectively.
Fat Oxidation : As coffee generates heat in the body, fat oxidation increases, i.e. fat breakdown takes place.
Appetite suppressant : Caffeine can suppress appetite and boost metabolism.
Burn Fat: What's the Best Time to Drink Coffee?
The best time to drink black coffee to burn fat is 30-45 minutes before exercise, when caffeine maximizes adrenaline and fat mobilization.
For non-workout days, mid-morning is best—between 9 and 11 a.m.—because cortisol levels are typically high early in the morning. Waiting until then, when cortisol levels have dropped, to drink coffee to boost cortisol levels is ideal.
Avoid caffeine after 4 p.m. to ensure quality sleep, notes Dr. Rajiv Kovil, a diabetes and weight loss specialist working in India.
How much black coffee should I drink per day?
The ideal amount of black coffee to consume per day is no more than 1 - 2 cups (maximum 200 - 300 mg caffeine/day) for most adults.
Drinking too much black coffee can increase cortisol, which can cause acidity, disrupt sleep, or increase anxiety, which can slow fat loss. Moderation is key. Most adults can safely drink one to two cups a day, preferably away from medication and not on an empty stomach if you are prone to acid reflux, Dr. Kovil advised, according to Hindustan Times.
