How many calories should I eat to lose 3 pounds a week?

Losing 3 pounds a week theoretically requires creating a calorie deficit of approximately 10,500 calories (3,500 calories per pound of fat). This translates to a daily deficit of 1,500 calories. The exact number of calories you should eat will depend on your current weight, metabolic rate, and activity level. However, it’s important to ensure that your calorie intake doesn’t drop too low, as this could harm your health. Aiming for 1-2 pounds per week is considered a safer and more sustainable goal. This theoretically requires a daily calorie deficit of 500-1,000, although many experts would suggest you stick closer to a deficit of 500 to avoid nutrient deficiencies and other complications.

Why am I not losing weight on a 1,200-calorie diet?

Not losing weight on a 1,200-calorie diet could be a result of several factors: Underestimating Calorie Intake: It’s common to underestimate how many calories you consume. By using apps and wearable tech, you can accurately track all foods and beverages you consume. Overestimating Calorie Burn: The calories burned during exercise or daily activities can also be overestimated, which leads to a smaller calorie deficit than needed. Metabolic Adaptations: When calories are significantly reduced, your body may adjust by lowering its metabolic rate to conserve energy, particularly if this caloric intake is maintained over a long period.

Will the body go into starvation mode with just 1,200 calories?

What happens when you significantly decrease your calorie intake may be more accurately described as metabolic adaptation. If you consume as little as 1,200 calories daily, especially for an extended period, your body may adapt by reducing its metabolic rate to conserve energy. This adaptation can make further weight loss more challenging. ( 15 ) However, this doesn’t mean that your metabolism stops and it becomes more efficient in using the calories provided. This response underscores the importance of focusing on both calorie quantity and the quality of the food consumed. 1,200 calories is not appropriate for everyone. You should talk to your healthcare provider or a registered dietitian for individualized advice and recommendations.
