How long will it take to lose 20 lbs on a 1200 calorie diet?

Can you gain weight on a caloric deficit?
A calorie deficit means that you consume fewer calories from food and drink than your body uses to keep you alive and active. This makes sense because it’s a fundamental law of thermodynamics: If we add more energy than we expend, we gain weight. If we add less energy than we expend, we lose weight.
How much of a calorie deficit Do I need to lose weight?
A good rule of thumb for healthy weight loss is a deficit of about 500 calories per day. That should put you on course to lose about 1 pound per week. This is based on a starting point of at least 1,200 to 1,500 calories a day for women and 1,500 to 1,800 calories a day for men.
What is a calorie deficit and how to achieve it?
To lose weight, you must create an energy deficit (aka calorie deficit). Months or years of consuming more calories than needed to maintain your weight leads to weight gain. To reverse this, you need to eat less, making the body use stored fat as energy which leads to weight loss (2). A calorie deficit can be different.
Do you lose a pound a week with a 500 calorie deficit?
Do you lose a pound a week with a 500 calorie deficit? It is a myth that by eating 500 fewer calories a day, you will slowly lose 1 pound of weight a week. This amounts to 3,500 fewer calories a week (7 days times 500 calories) and is sometimes referred to as the 3,500 calories per pound rule.
What happens if you eat too few calories?
A poor diet too low in calories is one that will cause fatigue and is not sustainable. Thus, calculating an ideal calorie reduction is key in order to sustain and maximize your goals. To work out your ideal and unique calorie deficit, you need to begin working out how many calories you need to burn each day.
What are the effects of restricting calories too severely?
