To lose fat effectively, several key strategies are recommended:

1. Strength training to build muscle and increase resting calorie burn.
2. Following a high-protein diet to reduce appetite and preserve muscle.
3. Getting enough quality sleep, around seven hours per night, to support metabolism and hormone balance.
4. Engaging in aerobic exercise (cardio) and high-intensity interval training (HIIT) to burn calories and reduce fat.
5. Reducing intake of sugar, refined carbs, and sugary beverages.
6. Adding probiotics and healthy fats to the diet for metabolic benefits.
7. Avoiding drastic calorie restriction to prevent muscle loss and rebound weight gain.

More specifically, strength training combined with aerobic exercise reduces belly fat more effectively than aerobic exercise alone. Eating protein-rich foods like meat, eggs, and legumes helps control appetite. High-intensity interval training burns more calories in less time and keeps the metabolic rate elevated after exercise. Low-intensity endurance exercise burns fat efficiently when oxygen supply is sufficient. Cutting back on sugary drinks and refined carbohydrates also aids fat loss. Good sleep habits help regulate hunger hormones and support fat loss efforts. Lastly, steady aerobic exercise like brisk walking for 30 minutes most days plus strength training twice a week is advised for sustained fat loss.

In summary, fat loss is best achieved through a combination of regular exercise (both strength and cardio), a high-protein and balanced diet, good sleep, and healthy lifestyle habits, avoiding crash diets and excess sugars.
