Surya Namaskar is basically yogic exercises comprising of mudras, asanas, pranayamas, visualisation and mantra and therefore also has mental and endocrinal effects in addition to general effects of physiological exercises. You mentioned that you want to practice suryanamaskar to lose weight. I would therefore presume that you are overweight and therefore you must be cautious of your wrists, ankles and knees, they pain much when suryanamaskar is done with weak muscles of these joints (these joints are come under more pressure) or beyond one's capacity. So, I would also suggest you to first practice sukshama vyayam before practising suryanamaskar, or start with 3-4 nos. daily in the morning, slowly repeat by 1-2 of it in the evening after one or two weeks. Then, you dont need to add suryanamaskar in the mid of the day. And do not go beyond your capacity to do in one stretch. Slowly increase your numbers.
In addition to suryanamaskar as a part of your regime to burn out extra calories, you must consult your nutritionist as well to have better results. This will have slightly permanent results as nutritional knowledge/ awareness will change your lifestyle leading to good physique and health.
