![]() Eating 3,500 fewer calories does not mean your body automatically burns 3,500 calories worth of fat. Unfortunately, the body does not work that way. It takes the simplistic view that the energy content of weight loss is 3,500 calories per pound because fat tissue contains approximately 3,500 calories per pound, so burning the equivalent number of calories will result in a 1-pound weight loss. It says that to lose 1 pound of body weight a week, eat 500 fewer calories daily (3,500 fewer calories weekly). There is a popular but inaccurate rule-of-thumb for weight loss that dates back to when there was limited understanding of fundamental metabolic processes. In that state, your body will compensate for the difference by extracting the extra energy from its energy stores to meet its daily calorie needs, resulting in weight loss from the breakdown of fat and lean body mass tissues. To lose weight, you need to consume fewer calories than your body burns, putting your body in an energy deficit state. The liver and muscles have a limited storage capacity for glycogen, so once the glycogen stores are full, the excess glucose is converted to triglycerides and stored in fat cells. When your body gets more glucose than it needs for energy, the surplus first gets sent to the liver and muscles and stored as glycogen for later use. Glucose (blood sugar) is the body's principal energy source from food. Your body requires energy to power its essential functions to maintain life and perform physical work. ![]() Consult a doctor for guidance and support if you consider consuming a diet of fewer than 1,000 kcal or 4,200 kJ per day. You can change your target date later to increase or decrease your required calorie intake. Nutrition therapists will tell you that, below those levels, you will not meet food group targets and nutrient recommendations. Otherwise, it will automatically modify your target date for a minimum daily intake of 1,200 calories for women and 1,500 for men. Remember, combining exercise with a small calorie deficit is the best intervention to maximize weight loss! Additionally, consuming a high protein diet (or sticking to the higher ranges based on your activity level) will help maintain and preserve muscle mass while losing fat.The calculator will only produce results if it determines the required food energy intake to reach your goal weight by the target date is more than 1,000 calories per day. Therefore, creating a calorie deficit of 500-1,000 calories per day can lead to a max weight loss rate of 2lbs/week. Taking this into consideration, it is more feasible to cut back on food since daily caloric requirements for maintaining weight are much higher. So keeping that in mind, the goal is to lose 1-2lbs per week.įor sedentary individuals, it would be recommended to set a goal of losing 1lb per week, which would equate to a calorie deficit of 500 calories/day.įor more active individuals, daily calorie requirements are higher in order to account for exercise and active lifestyles. More often than not, when weight loss exceeds 2lbs in a week, the majority of that is water loss. That would equate to a calorie deficit of 1,000 calories per day. ![]() See this blog on How Many Carbs Per Day for Weight Loss to learn more.įor healthy, sustainable weight loss, it is generally not advisable to lose more than 2 pounds of fat per week. Step 2: Divide answers in step 1 by 4 since there are 4 calories per 1 gram of carbohydrate Multiply daily calorie requirements by 0.45 & 0.65 to obtain calories from carbohydrates. Step 1: Calculating grams of carbohydrates. The Dietary Guidelines for Americans recommends that carbohydrates should make up 45-65% of one’s daily calories. Third: Calculate Daily Carbohydrate needs See this blog on How Much Fat Per Day for Weight Loss to learn more. Using both of these references you can calculate your daily fat needs: The Dietary Guidelines for Americans also recommends fat should make up 20-35% of one’s total daily calories. To prevent any fatty acid deficiencies it is recommended to consume at minimum 1g/kg of fat per day. Multiply weight in kilograms by range that best fits your activity levels. This is the last step of calculating calories, and it's one that's absolutely essential for getting accurate weight loss results.ĭid you know that protein is a huge catalyst for weight loss and hunger satiation? Let's compare and contrasts sedentary versus moderately active individuals and their protein requirements.įor sedentary/lightly active individuals: 1-1.2g/kg/dayįor moderately active - extremely active: 1.4-2.2g/kg/dayĬonvert body weight in pounds to kg’s (round to the nearest 10th)
