Thank you for using Ask a Doctor Service from doctor spring.

Using solar belt doesn't affect brain in any way, however I would advise you to involve yourself in more physical exercise and limit the use of solar belt. Neoprene, an insulating material, increases sweating. A solar belt may increase water weight loss around the waist because it prevents heat loss by insulating the area. As anyone who has attempted to lose weight with saunas or wraps can tell you, sweating doesn't cause lasting weight loss. Because of compression by neoprene and fluid loss, a solar belt can give the brief appearance of weight loss.  Exercising without a belt, unless your doctor or physical therapist advises wearing a weight belt, causes your body to engage more muscle. Wearing a solar belt can actually limit your exercise effectiveness. Increasing your temperature during exercise stresses your body and may reduce your energy and exercise intensity. Exercising in a solar belt without replacing fluids lost by the increased sweating can be harmful

Working your core muscles improves your posture. Good posture and a firm core help you look trimmer as you lose weight. Strong core muscles -- back, upper and lower abdominals and obliques along your sides -- give you a natural girdle. A conditioned core increases your strength and power for sports and daily activities, and reduces your risk of injury. Aerobic exercise and weight training coupled with cutting calories and limiting alcohol consumption will reduce belly fat.

Hope this helps. feel free to ask if you any further questions.

Thank you
