Ask AI: If you eat 800 calories a day how long would it take to lose 70 lbs?

I am not a nutritionist, but I can provide you with a general idea of how long it might take to lose 70 lbs based on a daily intake of 800 calories. Please consult a professional before making any changes to your diet. To lose 1 pound, you generally need to create a calorie deficit of 3,500 calories. To lose 70 pounds, you'd need to create a deficit of 245,000 calories (70 lbs x 3,500 calories). First, find out your daily calories needed to maintain your current weight. You can use a basal metabolic rate (BMR) calculator online for this. For example, let's assume that your BMR is 2,000 calories per day. Eating 800 calories a day would create a caloric deficit of 1,200 calories per day (2,000 - 800). Now, divide the total calorie deficit needed (245,000 calories) by the daily calorie deficit (1,200 calories): 245,000 / 1,200 ≈ 204. It would take approximately 204 days of maintaining this daily caloric deficit to lose 70 pounds. However, it's important to mention that consuming only 800 calories a day is not recommended, as it can lead to health problems and nutritional deficiencies. It is always best to consult a healthcare professional or a registered dietitian for personalized, safe, and effective weight loss plans.
