3 main causes of obesity :

The most common cause of obesity is burning fewer calories during daily activity than you consume daily over a long period of time . Over time, these extra calories accumulate and cause weight gain.

But it’s not always just a matter of calorie consumption and lifestyle. There are some reasons which are not in your control. Let us know about them.

  • Genetics, which affect how your body turns food into energy and stores fat
  • Aging, which can lead to lower muscle mass and metabolic rate
  • Not getting enough sleep , which can lead to hormonal changes that lead to overeating
  • Pregnancy
  • Some medicines, along with which you do not make changes in diet and activity, can increase your weight. Examples of such medicines are antidepressants, antiseizure medicines, sugar medicines, antipsychotic medicines, steroids and beta blockers

Some health problems can also lead to weight gain, which can lead to obesity. This includes :

Obesity treatment

The goal of obesity treatment is to reach and stay at a healthy weight. You may need to work with a team of doctors – a dietitian, behavioral counselor or obesity specialist – to understand and make changes to your eating and physical activity habits. 

All weight loss programs require changes to your eating habits and an increase in physical activity. The treatment methods that are right for you depend on your level of obesity, your overall health, and your willingness to participate in a weight loss plan. Other treatment tools include dietary changes, exercise, and physical activity.

Dietary changes

  1. Reducing calories and eating healthy foods are important in overcoming obesity. You might want to lose weight quickly, but it is better for your health to lose weight slowly. By doing this, the chances of gaining weight back are also less.
  2. Avoid unrealistic dietary changes, such as crash diets, as they weaken your immune system and put you at risk of dehydration .
  3. Continue the weight loss program for at least 6 months and the maintenance phase of the program for at least a year for best results.
  4. Choose a diet plan that includes healthy foods that you feel will work for you.
  • Calorie Reduction – You can lose weight by reducing your calorie intake. You and your doctor can keep track of your eating and drinking habits, how many calories you’re usually taking in, and where you can cut back. You and your doctor can decide how many calories you need to consume each day to lose weight. 
  • A typical intake is 1,200 to 1,500 calories for women and 1,500 to 1,800 calories for men.
  • Get fuller with less food – By eating larger portions of low-calorie foods, you can reduce hunger pangs.  
  • Make Healthy Choices – Eat fruits, vegetables and whole grain carbohydrates to make your overall diet healthy . Also emphasize sources of protein such as pulses, soy and meat (lean). If you like fish, try to include fish twice a week. Reduce the amount of salt and sugar. Consume low fat dairy products. Eat fats in moderation and make sure they come from heart-healthy sources, such as olive, canola and walnut oils.
  • Limiting certain foods – Some diets limit the amount of a particular food group, such as high carbohydrate or full fat foods. Ask your doctor what diet plans are effective that may be helpful for you. Drinking sweetened beverages will make you consume more calories, and limiting or eliminating these drinks is a good start.
  • Meal Replacement – Replace one or two of your meals with a low calorie shake or meal bar. Consume less calories and fat.
