Scientific research has proven that obesity is detrimental to health and carries the potential risk of certain diseases; similarly, being underweight also poses a hindrance to health.
Obesity is caused by excessive caloric intake and nutritional surplus. It goes without saying that being underweight is related to insufficient caloric intake and nutrient deficiency. In addition to a thin physique and fatigue, being underweight can lead to a decreased immune system, making one more susceptible to diseases.
Weight loss is common in people over 60 years of age. The reasons may include certain mental disorders in some elderly individuals, loss of appetite, tooth loss, unhealthy eating habits or picky eating, an unbalanced diet, or poor economic conditions that prevent them from consuming an adequate amount of food.
In fact, it is difficult for overweight people to lose weight, and it is by no means easy for underweight people to gain weight. According to observations, to gain 1,000 grams of weight per week, one needs to consume an additional 500-1,000 kilocalories of heat per day. Therefore, to improve weight loss in the elderly and help them gain weight, a high-calorie diet should be adopted, based on the following specific principles.
1. Balanced diet: Nutrition should be reasonable, with a hygienious combination of meat and vegetables, coarse and fine grains, and dry and wet foods. The total daily caloric intake should be over 3,000 kilocalories, with protein accounting for 12% of the total calories, fat 30%, and carbohydrates 58%.
2. Pay attention to cooking methods: Choose cooking methods suitable for the chewing and digestive capabilities of the elderly, such as blanching, stewing, boiling, simmering, and steaming. Food should be varied, and cutting techniques should favor shreds, minces, cubes, and slices. Seasonings that can stimulate gastric juice secretion and increase appetite should also be used.
3. Develop good eating habits: Eat定量 and on time. Chew slowly and savor your food to promote digestion and absorption. Maintain a pleasant mood during meals. Generally, two additional meals should be added in addition to the three main meals.
4. Examples of food composition: The daily menu can provide 300-400 grams of grains, 100-200 grams of coarse grains and tubers, 100-150 grams of poultry and meat, 300-500 grams of milk or soy milk, 1-2 eggs, 100-150 grams of bean products, 500-750 grams of vegetables, 100-200 grams of fruit, 40-50 grams of vegetable oil, 25 grams of sugar, and 6-8 grams of salt. The above dietary principles are for reference only. The specific implementation can be adjusted at any time according to individual circumstances, but it is essential to ensure adequate calories and a balance of various nutrients.
