You might decide to count calories on keto to help you reach your weight loss goals. While many people lose weight on keto without tracking calories, others find it useful to stay on the keto track, and it might help prevent you from overeating. Let’s discuss top tips for calorie-counting on keto.

How Can Counting Calories Help with Weight Loss?

Numerous health experts endorse the concept of ‘calories in vs. calories out’ and believe calorie-counting is a key part of the weight loss picture. ‘Calories in vs. calories out’ is a model based on the idea that to be more metabolically healthy and maintain stable body weight, the number of calories you consume needs to match the number you expend in energy.

Calories in refers to the calories you get from your food and calories out are the number of calories you burn as energy. With this model, you should achieve weight loss if there’s a calorie deficit, and you consume fewer calories than you’re burning for energy. On the other hand, if you’re consuming more calories than you’re burning for energy, you might gain weight, according to this model.

Counting calories might not be necessary for the beginning and transitioning to a ketogenic diet could just do the trick. Countless people lose weight just by switching out unhealthy foods for healthier keto-friendly options. If you reach a weight loss plateau, you might experiment with calorie-counting. 


How Many Calories Should You Eat to Lose Weight?

Calories give your body the energy needed to sustain life. Calories are units that measure energy, typically the energy content of beverages and foods. Caloric needs and nutritional requirements vary because each individual’s body, metabolism, and lifestyle are unique. 

2,000 calories are usually considered the standard daily intake. This number is based on the estimated nutritional needs of most adults according to the 2015-2020 dietary guidelines. It’s also often used as a benchmark to create nutrition label recommendations.

Depending on the activity level, adult women require an estimated 1,600-2,400 calories daily compared with 2,000-3,000 calories for adult men. Those in periods of growth and development, such as adolescents and pregnant women, often need more than the standard 2,000 calories.

Generally speaking, larger people, young adults, and men require more calories than smaller people, older adults, and women [1,2,3,4,5].

A 2,000-calorie diet might help some people lose weight, but myriad factors play a role, such as your age, height, weight, gender, activity level, and weight loss goals. 2,000 calories per day would exceed the calorie needs of some people and might result in weight gain.

For example, if you reduce your daily calorie intake from 2,500 to 2,000, you should lose around 1 pound in 1 week. This is because 3,500 calories (500 calories saved over 7 days) is the estimated number of calories in 1 pound of body fat.

Safe weight loss is typically around 1-2 pounds a week, but some health professionals believe that in most cases, losing a little more weight in a week won’t be a problem. To help you figure out how many calories you need to lose weight using these calories in vs. calories out model, you could try a weight loss calculator [6,7,8,9].

Online Calorie Counters and Weight Loss Calculators!

Certain apps and websites, such as My Fitness Pal or Lose It, can help you track your calorie intake and calculate the right number of calories for weight loss. Some experts recommend using a calorie counter for a few days to see how many minerals, vitamins, calories, protein, fat, fiber, and carbs you’re eating.

If you need help calculating your calories and/or macronutrients on keto, make sure to check out our Keto Calculator. Since you apart of Keto Club, you also have access to the Advanced Calculator.

The calculator requires this data because these factors influence your metabolism and the number of calories your body needs to function. It’s important you’re as honest as possible about your exercise and daily habits, so the calculator can give you the most accurate numbers, and you can get the best possible outcome. If you’re not sure how active you are, try keeping an activity journal for a week or looking at data from your fitness tracker.

If you exercise more, you’re burning more calories, and the calculator can adjust your daily calorie intake accordingly. Be careful that you don’t eat more calories than you burn after exercise [10,11].

You should also try to be realistic about your weight loss goals and your ideal body weight. You don’t want to set a goal weight below your healthy body mass index (BMI). Your ideal weight might not match up with your healthy weight. Working with a keto doctor or weight loss professional can help you achieve your weight loss goals safely and improve your general health and wellness.


Top Tips for Counting Calories on Keto

Cutting and monitoring your calories does require change, but it doesn’t have to be overly time-consuming or difficult. Making the following changes can reduce your calories:

  • Skip high-calorie, low-nutrition items (most aren’t keto-friendly anyway!)
  • Swap high-calorie foods for lower-calorie options
  • Reduce your portion sizes [12,13]

Meal-prepping is also useful, so you don’t fall off your calorie-counting keto track.


The Complex Weight Loss Puzzle

Weight loss definitely isn’t as simple as calories in vs. calories out, and different foods have a different metabolic effect in your body.

The same number of calories in a sugary granola bar and a head of broccoli doesn’t have the same metabolic impact in your body. Put simply, weight loss also involves insulin and hormones, the impact on your metabolism and the thermic effect of food, your gut bacteria (microbiome), and several other factors. The quality of your food is also important. A growing number of health and nutrition professionals now point to the quality of food rather than the number of calories when it comes to weight loss and human health [14,15].

Consuming foods with fiber and protein can help you feel more satiated when you’re cutting your calories. You can also try other methods to help you lose weight, such as exercising, reducing your stress, getting plenty of sleep, and drinking more water [16].
