To slim and tone your belly and achieve a more defined waistline, you can incorporate yoga poses, along with a balanced diet and regular exercise, into your daily routine. Here are some yoga tips and remedies that you can practice at home:

1. **Boat Pose (Navasana):** Sit on the floor with your legs extended. Lift your legs and balance on your sit bones, keeping your back straight. Reach your arms forward alongside your legs. Hold the pose, engaging your core muscles, and breathe deeply. This pose strengthens the abdominal muscles.

2. **Plank Pose (Phalakasana):** Start in a push-up position with your arms straight and shoulders directly above your wrists. Keep your body in a straight line from head to heels, engaging your core muscles. Hold the pose for as long as you can, building up strength over time.

3. **Bridge Pose (Setu Bandhasana):** Lie on your back with your knees bent and feet hip-width apart. Lift your hips off the floor, creating a straight line from your shoulders to your knees. Interlace your hands under your back to support the pose. This pose stretches and strengthens the core and back muscles.

4. **Cobra Pose (Bhujangasana):** Lie on your stomach with your palms placed under your shoulders. Lift your upper body off the floor, keeping your pelvis and legs grounded. Arch your back and look up. Cobra pose strengthens the abdominal muscles and improves flexibility in the spine.

5. **Wind-Relieving Pose (Pavanamuktasana):** Lie on your back and bring your knees towards your chest. Hug your knees and gently rock from side to side. This pose helps in relieving bloating and gas, supporting a flatter belly.

6. **Child’s Pose (Balasana):** Kneel on the floor and sit back on your heels. Extend your arms forward and lower your torso between your thighs. Hold the pose, relaxing your belly and back. Child’s pose is a gentle stretch that can help in relieving stress and tension.

7. **Twisting Poses:** Poses like seated or supine spinal twists can help stimulate digestion and aid in detoxification, promoting a healthier belly.

8. **Breathing Exercises (Pranayama):** Incorporate deep breathing exercises like belly breathing or diaphragmatic breathing to relax the abdominal muscles and reduce stress.
