Calories required depends on a person’s height, weight, age, degree of exercise, biological sex, and possibly inherited features Formulas have been created to help people figure out how much they need, but it’s vital to remember that everyone is different and that even the best calculations occasionally miss crucial details.

What are Calories?

Calories are the energy that a food or beverage contains. On food items, calories are typically listed, and wearables like the best fitness trackers let you keep track of how many calories you burn while engaging in various activities. More calories are typically found in certain foods, such as those that are fatty, fried, or processed. 

Fresh fruit and vegetables, for example, have fewer calories on average than other foods. Conversely, low-calorie foods like diet soda have no nutritional value while some nutritious fruits and vegetables can have a high-calorie content.

This amount is sufficient to keep the average person’s body and mind functioning, but if continued for more than a few days, it can still have a detrimental effect on that person’s general health. 

Everyone is unique, of course, and some people require more calories than others to keep their bodies from going into starvation mode. If you spend your days lounging around the house watching Netflix, you might be able to get by on less than 1,200 calories per day. However, you’ll burn a lot more if you’re stranded in the wilderness, fretting about your future, and struggling to survive.

What Foods Are High in Calories?

You will undoubtedly want to eat whatever food is on hand in a true emergency. However, you should keep foods that are high in calories and nutrients on hand. Although leafy greens are high in nutrients, their low-calorie content makes it unlikely that they would keep you full for a long time.

1. Peanuts

For many years, peanut butter has been a mainstay of the diets of hikers. Back up a bit and try some peanuts. They not only contain healthy fat, but salted varieties also help replenish the sodium lost through perspiration.

2. Avocado

Many people in the health sector see avocados as superfoods since they are packed with nutrients, including 42% of the daily required amount of fiber in only one avocado.

It is healthier to choose dark chocolate with 70% cacao or more in it because it offers heart-healthy qualities and much less sugar.

4. Brown Rice

Unlike white rice, which lacks many vitamins and minerals, brown rice also known as wild grain rice contains these nutrients in addition to complex carbs for energy, making it a fantastic survival food. Additionally, brown rice is a food that requires only the addition of water to become edible and is light in weight.

5. Oats

Oatmeal, of course, is made from oats and is quite nutritious, with a higher calorie content than white rice. Both are low-cost foods that may be obtained in quantity. The difference with oatmeal is that you get a lot more nutritional value for your money.
