Dietary therapy for obesity in the elderly and pregnant women: a special focus on scientific weight loss

Weight Loss Diet Requirements for Special Populations:

Dietary Therapy for Elderly Obese Patients:

For mildly obese elderly patients, dietary therapy is generally not necessary. Severely obese patients should pay attention to the following aspects when using dietary therapy for weight loss:

First, eat at regular times each day, chew slowly and thoroughly, and spend 20-30 minutes on each meal. Avoid overeating at each meal. If the elderly feel hungry between meals, they can eat some fruit, such as apples or bananas.

Second, skip staple foods for breakfast, and only eat eggs, milk, or soy milk; if staple foods are consumed, do not exceed 100g. For lunch, focus on vegetables, lean meat, and soy products, reducing the amount of staple foods; the amount of staple foods for lunch should not exceed 150g, and you can choose 2-3 types, such as 50g rice, 100g steamed buns, or only 100g rice, or only 150g steamed buns. Eat plenty of vegetables. For dinner, bean porridge is preferable, or vegetable porridge is also acceptable. Eat until you are 60% full, and avoid meat at dinner. Eat an apple 1-2 hours after dinner and before bedtime.

Third, use primarily vegetable oils when cooking; preferably use coarse salt (not refined salt); eat brown sugar, but avoid white sugar. Drink warm or lightly boiled water daily, drink less weak tea, avoid cold drinks, and avoid snacks.

Fourth, aim for a weight loss of 1kg per month, without feeling hungry or experiencing general weakness.

Fifth, medicinal diet therapy can be used under the guidance of a doctor.

Dietary Treatment for Obese Pregnant Women: During pregnancy, women often overeat to promote fetal development, leading to overnutrition. On the other hand, reduced physical activity due to physical limitations contributes to weight gain. Pregnant women need adequate nutrition, but excessive obesity should be avoided. Obesity is detrimental to both the baby and the mother.

Dietary principles for weight loss during pregnancy: Insufficient maternal nutrition during pregnancy can lead to premature birth or low birth weight infants, and also increase infant mortality or developmental delays. The recommended minimum calorie intake for obese pregnant women is 1500 kcal. This level should not be lowered, otherwise, it will be difficult to meet nutritional needs.

For pregnant women engaged in light physical labor, it is recommended to increase daily calorie intake by 300 kcal in the second half of pregnancy to meet the needs of fetal and placental tissue growth. If the pregnant woman is engaged in general physical labor, the daily calorie increase can be more than 300 kcal.

The pregnant woman's diet should also control carbohydrate and fat intake, but protein intake should be sufficient, as the fetus needs more nutrients, especially vitamins and minerals. Each meal should include plenty of fresh vegetables and fruits. When edema occurs, more rest is needed, and the diet should be low in salt, which is also beneficial in preventing gestational hypertension. Iron and folic acid supplementation is also necessary during pregnancy, and foods containing calcium, phosphorus, and vitamin D should be consumed, as these are necessary for fetal bone growth.
