what are the physical and mental stages of obesity?

Answer 1

There are many psychological reasons why people over eat. Have never heard of any stages. It's often more complicated than people think.

Answer 2

Did you mean to say 'states' of obesity? Obesity is caused by eating too much to satisfy a warped desire for pleasure. Here's a bunch of information on weight loss. The part about the psychology of overeating is particularly interesting.

Losing weight really is as simple as basic addition and subtraction. If the calories you eat add up to more than what you burn in a given time period, you will gain weight. Conversely, if you eat fewer calories than you burn, you will lose weight. Depending on your size and activity level, the number of calories will vary quite a bit. The secret is finding your “break even” calorie intake level. For most people, the “ball park” figure will be around 1800 to 2000 calories per day. If you are larger than average, this number will be higher, lower if you are smaller than average. Metabolic rate can have an effect on these numbers as well. Exercise plays an important role also, as this can increase the number of calories you burn by quite a bit as well as increasing your metabolic rate.

If you want a generally healthy diet that’s easy to follow and avoids hunger, the one I recommend will do the job very well. You can fill up and still lose weight. Eat lots of fresh vegetables as they contain very few calories yet are full of good nutrition. The less you cook them, the more nutrition they retain. Stick with whole grains, as they tend to be better for you and don’t turn to sugar as readily as processed grains do. For example, whole grain bread is much better for you than plain white bread. Eat a variety of fruit on a daily basis. Avoid empty carbs, fats, and sugars…. Examples: junk food and soda. If you feel you need protein to build muscle, add some chicken or fish to your diet. Avoid beef and dairy products, the cons outweigh the pros.

If you can’t get your mind into the ‘eat to live; don’t live to eat’ mode, you should probably read this short article on the psychology behind overeating:
