If you are over weight, it is indeed recommended to lose that extra from your body. This is must for physical and psychological wellbeing. But wait. Do not jump into weight loss by whatever comes to your mind or whatever crosses your sight. Weight loss is good but unplanned weight loss or weight loss by wrong methods can damage health. Some popular methods only remove water from the body which gives a feeling of weight loss. But this has serious effects on health. Water loss from body is not weight loss. Another serious mistake is to try a drastic weight loss say for example 15 kg in 40 days. This has major side effects as body is not able handle such sudden change and body organs get affected resulting in many chronic diseases. Various nutritional deficiencies can also result if diet is severely restricted without giving consideration to necessary body requirements. This can also result in hormonal and psychological disbalance. Medically recommended weight loss is 0.5 kg – 1 kg per week or 2 – 4 kg a month. Your weight loss program must answer following questions :
- What am I losing – fat or water ?
- How much I need to lose ?
- How am I going to lose this ?
- In what duration I will lose this ?
- Will this program affect my health negatively or positively ?
- How will this avoid nutritional deficiency ?
- Are there some hidden / unexplained products or drugs or methods ?
- How will I maintain what I will lose ?
Causes Of Obesity
- Over eating & unhealthy eating (eating more calories than consumed).
- Insufficient physical activity.
- Poor lifestyle
- Medical condition like hypothyroidism, hypogonadism, cushing syndrome etc
- Prosperity and modernization
- Psychological factors like bulimia, eating linked to emotions (stress, anxiety etc)
Assessment of Obesity
There are several methods to assess over weight and obesity states. Some are :
- Height Weight Range : These are easy to use height weight charts for both males and females. It gives a range of recommended body weight. Some charts gives weight for short, medium and big statures.
- Brocas Index : According to Brocas Index the ideal weight of a person is equal to height of the person in centimeters minus 100. For example if a person’s eight is 170 cm then the ideal weight would be 70 kg. Above that is overweight and above 20 % of ideal weight would be obese.
- Body Mass Index : In BMI method weight in kg is divided by height ² (in meters)
For example if a person is 92 kg in weight and has a height of 169 cm then the BMI would be 92 / 1.69 x 1.69 = 32.21
BMI is graded as follows
Less than 25 – Not Obese
25 – 29.9 – Grade I Obesity
30 – 40 – Grade II Obesity
Above 40 Grade III Obesity
- Skin Fold Test : In this method subcutaneous fat (under the skin) is measured using skin fold calipers. The various sites of measurement are – at triceps, abdomen, above hip, subscapular upper back, bicep mid arm etc. For example anything above than 35 cm (females) and 40 cm (males) at waist is indicator of over weight. Body fat in %age can be calculated as follows :
Skin fold in mm % age of total body fat
15 – 45 mm 8 – 22 %
46 – 75 mm 23 – 30 %
76 – 150 mm 31 – 40 %
151 – 170 mm 41 – 45 %
Normal body fat upto 22 % males, upto 30 % females
Grade I Obesity upto 40 % fat
Grade II Obesity upto 45 % fat
Estimation of weight Loss
Excess fat is deposited in body as adipose tissue. This adipose tissue consists of 75 % fat, 23 % water with small amount of proteins & minerals. Each kg of adipose tissue contains 7700 kcal. This means to lose one kg of this adipose tissue either one need to burn 7700 kcal by exercise or take a diet deficient by 7700 kcal over a period of time. Lowest recommended calories for females is 1200 and for males 1500. Ideal body weight reduction is 0.5 kg – 1 kg per week.
Weight Management Options
- Energy Balance : The basic rule of weight loss is to create a negative energy balance i.e. to take less calories than what will maintain weight and burn some. But this should not be done at the cost of depriving body its basic nutritional requirement.
- Diet : Dieting is not starvation. Weight reducing diet must be carefully planned. A diet with 500 – 1000 calories less than daily calorie recommendation is ideal for safe weight loss. It must provide adequate proteins, vitamins and minerals. Lowest recommended calories for females is 1200 and for males 1500. A simple way to calculate calories is current weight x 24 – 500. If your current weight is 85 kg then a diet of 85 x 24 – 500 = 1540 calories would be good. Diet must contain less fat and more fibres. Food with high glycaemic index must be avoided. One must be consistent in eating habits avoiding erratic patterns. Avoid soft drinks, sweets, cakes, candies, fried food, cream, butter, alcohol, fruits like grapes, dried fruits, refined carbohydrates etc. Take whole grains, leafy vegetables, fruits like apples, salad etc.
- Exercise : Exercises are must for safe and lasting weight loss. These help in burning calories and improve body metabolism. Low intensity sustained exercises like aerobic exercises are most suitable. To be more effective they must be done under trained professional. Brisk walking, jogging, swimming, cycling are also helpful.
- Lifestyle : Develop a healthy lifestyle. Improve your awareness about weight metabolism, food, exercise etc. Having organized life, low stress and positive relationships all help in better weight management. (See Lifestyle Management)
- Medical treatment : Diseases which causes obesity must be thoroughly investigated and treated. Conditions like hypothyroidism, hypogonadism, cushing syndrome causes obesity which will be difficult to manage unless these conditions are well treated. Sub clinical hypothyroidism is the cause of obesity in many people which remains undiagnosed.
- Drugs and Surgery : There are some medical options available for weight management like drugs and surgery. But these must be reserved only for very specific conditions to be decided by appropriate doctors. They have their own complications and side effects so must not be used as ‘easy’ way of weight management.
- Clinical Acupuncture – It is highly effective in weight management by balancing the energy system of the body, by removing the obesity disease producing blocks and by balancing the five basic elements. It also corrects hormonal imbalance.
- Yoga : Yoga is very helpful for weight management. It improves metabolism, corrects hormonal & other medical conditions, removes water retention, keeps skin healthy and maintains vigor & vitality during and after weight loss. It improves will power and self esteem which helps in weight management.
- Homeopathy : Constitutional homeopathy is useful aid in weight management. Homeopathy improves body functions & metabolism. It can help in normalizing appetite, removing food cravings, correcting psychological disorders like bulimia etc.
- Counseling and Psychotherapy : One major barrier in weight management is negative attitude & behavior. Lifestyle, eating habits, exercise and many emotional conditions associated with obesity has attitude and behavior in background. Counseling & psychotherapy helps in assisting at psychological level and developing positive attitude & behavior. Psychological dependence on food, impulsive eating, lack of motivation, stress etc can be corrected by counseling and psychotherapy.
- Hypnotherapy : One of the most potent weapon in fight against obesity. It has capacity to help by changing subconscious mind to reduce big appetite, food craving, compulsive eating and other psychoemotional issues causing obesity. It can improve will, motivation and self image.
