I hope people like me wont be forgotten in this new obese world - seriously underweight, and struggling to do anything about it.

The statement that we do not consume more kilojoules than previous generations is often made but is incorrect. Comparisons made between the two National Nutrition Surveys in Australia showed clearly that our total kilojoule intake had increased. The greatest increase occurred in 10-15 year-olds. Boys in this age group increased their kilojoules by 1500 per day while girls in the same age group increased by over 900 kJ/day. These results have been published. See Cook T, Rutishauser I, Seelig M. Comparable data on food, nutrient intake & physical measurements from 1983, 1985, 1995 national nutrition surveys. 2001.

There are other studies showing great increases in intake among 4-8 year olds.

The first thing we need to get right are the causes of obesity.
Causes are not a simplistic calories in- not enough calories- out.
There are many overlooked causes including viruses,(eg Borna Virus) pre-natal environment and nutrition, genetics, dugs -like the very popular Zyprexa & Lyrica -lack of Omega-3, SLIRP gene, high fructose and corn syrup in foods,sleep disorders, missing meals (lifestyle factors),absence of breast-feeding, relative efficiencies of people's metabolism/digestive systems.
There is an excellent article on all this in the NY times archives (Fat Factors)QUOTE “And we documented that fat people do eat too much — our subjects ate an average of 6,700 calories a day. But what was so impressive to me was the fact that not all fat people eat too much.”

The recent International Conference on Obesity in Sydney did not attract ONE news report
We ignore the multi-faceted causes of obesity at our cost and peril.
