<human>:  What are the best systems of weight-loss that are not overly restrictive?
<bot>: The best systems of weight-loss that are not overly restrictive involve a balanced diet and regular physical activity. A balanced diet typically consists of five to six smaller meals a day, each containing a mix of lean proteins, complex carbohydrates, and healthy fats. Also, regular physical activity like brisk walking, jogging, swimming, or biking for at least 30 minutes a day is highly recommended. Staying mindful of your eating habits and setting realistic goals can be just as effective as any restrictive diet.
