The purpose of the study is To investigate the adding effect of Cryolipolysis to aerobic exercise with low caliorie diet on waist-to-hip ratio , ultrasonography, body mass index and skin fold of subcutaneous fat tissue in abdominal adiposity in obese subjects

Obesity is a serious disease marked by an increase in body weight of at least 20% over the ideal weight due to an accumulation of body fat.

The prevalence of obesity has hit epidemic levels over the past few decades, and numerous obesity-related illnesses, including heart conditions, certain types of cancer, and diabetes, have risen concurrently. Weight loss through lifestyle modification, including a hypocaloric diet and/or increased physical exercise, along with behavioural techniques to support these changes, is the basis for treating or preventing these diseases through therapeutic intervention. Such methods rarely result in an obese person reaching a normal body weight because the typical weight reduction from lifestyle change is between 5 and 10% of baseline weight.

Recently, studies have used numerous devices, including cavitation, radiofrequency, cryolypolysis, and other many devices, according to the World Health Organization, to solve this issue.

The FDA has approved the cryolipolysis device for cutaneous cooling as well as a number of other uses. Cryolipolysis is a novel non-invasive technique for the selective reduction of fat cells with controlled, localised cooling.

Clinicians use the waist measurement and waist-to-hip ratio to assess abdominal obesity. These actions have a clear correlation to many vascular diseases, including atherosclerosis and the risk of developing acute coronary syndromes.

Typically, low-calorie diets are low in fat ( 30% of energy intake), high in carbohydrates (55-60% of total daily energy consumption), and energy-reduced (deficit of 2100-4200 kJ/d: ) minimum of 4200-5040 kJ/d for women and 5040- 5880 kJ/d for men) Due to the acutely high energy cost and ability to increase fat utilization, aerobic exercise is frequently recommended in conjunction with calorie restriction. Numerous studies examined the effects of modest caloric restriction alone or in combination with aerobic exercise.According to studies, a walk/jog programme enhanced body fat reduction compared to a group that only followed a diet.

There is a gap in the literature regarding combining cryolipolysis and aerobic exercise for losing weight, particularly abdominal adiposity, despite the fact that numerous studies have supported the efficacy of each on weight loss. Therefore, the goal of this research is to ascertain whether losing abdominal adiposity would be more successful when cryolipolysis and aerobic exercise were combined.
