Losing belly fat typically takes several weeks to months and depends on various factors including diet, exercise, metabolism, starting weight, and consistency. Here are the key points:

• To lose 1 pound of fat, you need to burn about 3,500 calories. Creating a daily calorie deficit of 500 calories can lead to losing about 1 pound per week, which translates to roughly 4 pounds per month. This gradual fat loss will include belly fat reduction as part of overall body fat loss

• A realistic timeline to achieve a flatter stomach is generally around 6 to 12 weeks with a consistent calorie deficit combined with exercise. Those with more belly fat may require a longer period, while some may start seeing changes as early as 4 weeks

• Spot reduction (losing fat from just the belly) is not effective; overall body fat must be reduced through a combination of diet and exercise

• Aerobic exercise (like walking or running) and resistance training both support fat loss, and more frequent or longer-duration exercise can accelerate results. For example, 300 minutes of aerobic exercise weekly yields more fat loss than 150 minutes

• Other factors such as quality sleep and stress management also influence belly fat loss by regulating hormones and metabolism

• Weight loss is not always linear; some weeks may show more progress than others, but maintaining healthy, sustainable habits is crucial

In summary, expect to spend at least 4 to 12 weeks to see noticeable belly fat loss with a consistent calorie deficit, regular exercise, and healthy lifestyle habits. The exact duration varies individually, but steady and sustainable fat loss is the most effective approach.
