Women over age 60 generally require even fewer calories and typically need to consume around 1,—2, calories per day to maintain their weight 7.
Keep in mind that the exact number of calories that you need may fall on the high or low end of this range, depending on how active you are, along with your height, weight, and health status. Additionally, note that these estimates do not apply to those who are pregnant or breastfeeding , as these individuals have significantly higher calorie needs. The most recent Dietary Guidelines for Americans estimates that men between the ages of 19—30 should consume approximately 2,—3, calories per day to maintain their weight.
Energy needs decrease as you get older. In fact, men between the ages of 31—59 need about 2,—3, calories per day to maintain their weight 7. Meanwhile, men who are over 60 generally require 2,—2, calories per day to maintain their weight.
Men who are very active or have certain health conditions may require a higher number of calories. The number of calories that you need can also vary within this range based on your height and weight. Energy needs for children and teens vary based on their sex and age. A 3-year-old child might need only 1, calories, but a teenager can require closer to 3, calories 7. Simply put, a calorie is a unit that measures energy. Calories are usually used to measure the energy content of foods and beverages.
To lose weight, you need to eat fewer calories than your body burns each day. Conversely, to gain weight, you need to consume more calories than you expend 1. Developing a healthy diet and lifestyle plan that will help you lose weight and keep it off in the long term requires much more than determining your current calorie needs and then eating fewer calories on a daily basis 9.
Although decreasing the number of calories you consume can be effective for weight loss, cutting calories without considering which foods you eat is not a sustainable way to lose weight. For example, choosing more nutrient-dense foods — think whole grains, nuts, vegetables, and fruits — will benefit your health more than opting for nutrient-poor ones like soda, donuts, and candy.
When it comes to losing weight, protein is incredibly important. Studies show that increasing your intake of protein may help keep you full and curb your appetite 10 , Protein may also help fight cravings.
According to some research, high protein snacks can help enhance feelings of fullness while also decreasing hunger and appetite Plus, in addition to promoting weight loss, some research suggests that maintaining a high protein eating pattern could help prevent or reduce weight regain and help maintain muscle mass 13 , Therefore, if you want to achieve long-lasting, sustainable weight loss, consider increasing your protein intake by adding foods like eggs, meat, poultry, tofu, nuts, seeds, or legumes to your diet.
Increasing your protein intake can help you stay satisfied and consume fewer calories. This may help you lose weight and keep it off. Another relatively easy change you can make is to limit your intake of sugar-sweetened beverages, including sodas, fruit juices , chocolate milk, and other beverages with added sugar. Additionally, studies suggest that consuming sugary drinks is associated with an increased risk of obesity 16 , The harmful effects of sugar also go far beyond weight gain.
In fact, added sugar can contribute to other health issues, including heart disease, liver problems, and type 2 diabetes Sugar-sweetened beverages are high in calories and added sugar. If we take in too little energy, we will lose weight, fat, and eventually muscle mass. The type and amount of food we eat determine how many calories we consume. For many people on a weight-loss diet, the number of calories in a food is a deciding factor in choosing whether or not to eat it.
How and when we eat can also make a difference, as the body uses energy differently throughout the day. According to the Dietary Guidelines for Americans, women are likely to need between 1, and 2, calories a day, and men from 2, to 3, However, this depends on their age, size, height, lifestyle, overall health, and activity level. The Dietary Guidelines for Americans recommend a calorie intake that ranges from 1, calories a day for an infant of 2 years to 3, for an active male aged 16 to 18 years.
This reduces their need for energy. From age 19 to 25 years, the recommended intake for women is 2, calories a day, but after 51 years, this falls to 1, Around 20 percent of the energy we take in is used for brain metabolism. Most of the rest is used in basal metabolism, the energy we need when in a resting state, for functions such as blood circulation, digestion, and breathing. In a cold environment, we need more energy to maintain a constant body temperature, as our metabolism increases to produce more heat.
In a warm environment, we need less energy. Cellular respiration is the metabolic process by which cells get energy by reacting oxygen with glucose to produce carbon dioxide, water, and energy. How efficiently energy from respiration converts into physical—or mechanical— power depends on the type of food eaten, the type of physical energy, and whether muscles are used aerobically or anaerobically. In other words, we need calories to fuel bodily functions, such as breathing and thinking, to maintain our posture, and to move around.
Here are some tips for burning energy and losing weight more effectively. Eat breakfast : A protein and healthy fat breakfast can keep you full for longer and help prevent snacking during the day.
Eat regular meals : This can help you burn calories more effectively and helps prevent mindless snacking. They are high in nutrients and fiber and low in calories and fat. Eat slow-burning calories : High-fiber carbohydrates , such as legumes, and healthy fats, such as avocado, take longer to release energy, so you will not get hungry as quickly.
Exercise : This can help burn off extra calories, and it can make you feel good. A brisk daily walk is easy for most people to do and costs nothing. Challenge yourself with a pedometer. For people who use a wheelchair , there are exercises that can boost heart health and strength. Drink water : It is healthful, has no calories, and can fill you up. Avoid alcohol and sodas as these can easily provide far too many calories. If you crave sweet drinks, choose unsweetened fruit juices, or better still, get a juice maker.
Eat more fiber : Fiber, found in fruits, vegetables, and wholegrains, can help you feel full and encourage healthy digestion. Check the label : Some items have hidden fats or sugars. If you are counting calories, the label will help you keep track.
Use smaller plates : Research indicates that portion sizes have increased over the last 3 decades, and this may contribute to obesity. Using a smaller plate encourages smaller portions. Need help with the basics of weight loss? Read our straight-forward guide. The "Extreme Fat Loss" level is effectively a rock bottom calorie level. Do not attempt to immediately drop your calories to this level hoping for the quick fix. This may ultimately backfire.
The Extreme Fat Loss level shows the lowest calorie amount that can be considered. It should be seen as the exception rather than the rule. It becomes more efficient at using energy lowered metabolism , and therefore burns less fat. This is why most of us reach a weight loss plateau. You often find that the nearer you get to your goal weight or body fat percentage — the harder things get!
The 7 Day zig-zag provides a suggestion for daily calories that will keep your body guessing — and increase your chances of continual weight loss. It is difficult to set absolute bottom calorie levels, because everyone has different body composition and activity levels. Health authorities do set some baselines — these are calories per day for women, and calories per day for men.
Or someone who is tall, muscular, and exercises a lot? Try not to lower your calorie intake by more than calories below maintenance. Doing so may invoke the bodies starvation response, which can lead to the Yo-yo dieting effect. Try to gradually lower calories. A sudden drop such as calories or more can cause your metabolism to slow. Learn to eat slowly — research shows that faster eaters are heavier people 1. You are completely set-up for a regain in fat if you suddenly return to your previous eating patterns.
As your exercise level was already factored into the equation, there is NO NEED to subtract calories burned by exercise. For you this could mean a brisk walk, for others it could be a slow jog. It could be a session of weight-bearing exercises.
