The reality is that when you lose weight, you lose fat along with lean tissue in muscle - not just fat. 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. 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. Enter a time frame for your goal weight (start date and target date). If you are unsure of your physical activity level, start with the default - the worst-case scenario. Physical activity levels can range from 1.4 (little activity) to 2.3 (very active). Click the Physical Activity field to find your physical activity level. Enter your age, sex, height, current weight, and goal weight.
