Why is Gaining Weight Important?

Gaining weight is often important for those who are underweight and/or those who have experienced unintended weight loss.

Underweight

Some people are just naturally thin. They’ve always been that weight and that’s OK. Other people lost weight due to illness or some life event and they were never able to get the weight back on.

Those who are underweight often want to gain weight to get to a “healthier weight” for their height and age. Gaining weight and gaining muscle can be very important for staying healthy with aging.

In fact, for older adults, having a slightly higher weight is associated with decreased risk of death. You can learn more in our article on BMI in the Elderly.

How to Gain Weight

Gaining weight may sound simple when you explain it. But anyone who has struggled to gain weight knows it is not simple at all. Successfully gaining weight is based on many different factors.

High Calorie Diet

The best way to gain weight is to follow a high calorie diet. Simply put, if you eat more calories than you burn you will gain weight. The goal is to have a calorie surplus. Consuming more calories than you are currently eating so you can gain weight.

Examples of foods high in calories include whole fat milk, whole fat yogurt, avocado, coconut, nuts, nut butters, seeds, butter, bananas, ice-cream, etc.

You can learn more about high calorie foods at our article, The Best Weight Gain Food List. Or purchase our High Calorie Foods SERIES which features a high calorie foods list, grocery list, and meal planner.

Reading the nutrition label on food containers is a good way to find out how many calories are in the foods you are eating. At the grocery store you can compare the calorie content of the foods you purchase by reading the labels first.

A good tip is to avoid foods labeled with “diet”, “light”, or “reduced.” These foods are typically lower in calories. And they are often marketed towards people trying to lose weight.
