Overweight and obesity in the United States among adults and children has increased significantly over the last two decades. Those following typical American eating and activity patterns are likely to be consuming diets in excess of their energy requirements. However, caloric intake is only one side of the energy balance equation. Caloric expenditure needs to be in balance with caloric intake to maintain body weight and must exceed caloric intake to achieve weight loss (see tables 3 and 4). To reverse the trend toward obesity, most Americans need to eat fewer calories, be more active, and make wiser food choices. Prevention of weight gain is critical because while the behaviors required are the same, the extent of the behav iors required to lose weight makes weight loss more challenging than prevention of weight gain. Since many adults gain weight slowly over time, even small decreases in calorie intake can help avoid weight gain, especially if accompanied by increased physical activity. For example, for most adults a reduction of 50 to 100 calories per day may prevent gradual weight gain, whereas a reduction of 500 calories or more per day is a common initial goal in weightloss programs. Similarly, up to 60 minutes of moderate to vigorousintensity physical activity per day may be needed to prevent weight gain, but as much as 60 to 90 minutes of moderateintensity physical activity per day is recommended to sustain weight loss for previously overweight people. It is advisable for men over age 40, women over age 50, and those with a history of chronic diseases such as heart disease or diabetes to consult with a healthcare provider before starting a vigorous exercise program. However, many people can safely increase their physical activity without consulting a healthcare provider. . | NORTHERN SYDNEY CENTRAL COAST NSWQHEALTH Nutritional Care of the Housebound Elderly Notes from the Conference held at the University of Sydney 4 November 2005 May 2006 The University of Sydney The Conference was supported by the Australian Nutrition Trust and Sydney University Nutrition Research Foundation and Gosford Hospital Northern Sydney Central Coast Area Health Service If you have comments or would like to obtain further copies of this booklet contact - Nutrition Department Gosford Hospital PO Box 361 GOSFORD NSW 2250 E-mail rbartl@nsccahs.health.nsw.gov.au Thanks to Rachel Moerman and Marianne Alexander for help with this project. The University of Sydney Committee on Nutrition for Older Australians Sydney University Nutrition Research Foundation Presents NUTRITIONAL CARE OF THE HOUSEBOUND ELDERLY A One-day Conference Friday 4 November 2005 One-day Conference Veterinary Science Conference Centre University of Sydney The Committee on Nutrition for Older Australians CNOA is organising a one-day conference on Nutrition for the Housebound Elderly. This is the first conference on this topic to be held in Australia. Speakers include both experts and practical field workers refer to the list on the next page for details . Field workers and representatives of patients organisations are invited to attend. We expect to hear about the food and nutrition needs and problems of this growing section of the community what different organisations of field workers are achieving what challenges they see for the future and perhaps what research might help. This conference may help to remind the whole community of the importance of helping our housebound older people keep well fed and nourished. Members of the planning committee CNOA have been involved in writing and popularising NH and MRC s Dietary Guidelines for Older Australians 1999 and researching and preparing the Best Practice Food and Nutrition Manual for Aged Care Facilities 2004 .
