Fat people are always overweight, but thin people are not necessarily underweight. How can you tell if your weight is normal for you? Use our ideal weight calculator to determine.
If you are 10 or 15kg below your ideal weight, and if your body is bony, with only a thin covering of muscle tissue on your back, buttocks, and thighs, you are very likely underweight.
Let your doctor decide whether your extreme thinness is due to ill health or to your failure to eat enough of the right kinds of food. If she thinks that your diet is inadequate, she will be able to guide you to the calorie-rich foods suitable for your needs.
Concentrate on high-calorie foods such as cream soups, mayonnaise, cereals with milk or cream and cream-rich desserts. But be sure to check first with your doctor about the cholesterol problem because you will probably be eating large quantities of whole-milk food and eggs.
Peas, potatoes, and lima leaves provide more carbohydrates than the leafy vegetable you may have been eating, but don’t give up salads. They help with digestion, and because of all the starches and sugars in your new regimen, you will need to maintain some bulk in your diet.
Try not to eat sweets, they only increase the possibility of tooth decay and give you few nutrients beyond the sugar they contain. Snacks such as fruit, peanut butter and eggnog furnish protein, minerals and vitamins as well as calories.
Be sure to watch your weight. If you find that you are developing a sweet tooth and adding pounds rapidly, slow down—and check with your doctor. He may wish to modify your diet.
If your doctor has determined that your underweight issue isn’t medically related, then you can follow these tips [1] for gaining weight:
