How much is the best calorie intake when doing 16:8 intermittent fasting?

[Anonymous]

I take 500-1000 calories per day, and I do it 5 (sometimes 6) days a week. I've read that this is the recommended amount of calories per day for women doing 16:8 intermittent fasting. Plus, I work out 6 days a week. Is this setup okay?

No matter what kind of dieting you do, you need to get your daily energy (calorie) requirement.
I have a rough rule of thumb of 125 kJ per kg body weight to maintain body weight at moderate daily physical activity. According to this, I'd estimate you to weigh 35-40 kg (based on 1000 kcal), which not many people do.
Even if you're trying to lose weight, I think you're taking in too few calories. Try searching online for a daily energy calculator and find out you approximate requirements. From there just look in the mirror or weigh yourself from time to time and adjust the amount of food you eat based on whether or not you're seeing the results you want.

Thank you, this is helpful. I've seen some comments on the internet that 500-1000 calorie intake might be too few for a day and that it might also wreck someone's metabolism coz of not having enough energy.

I’d do enough to maintain your Basal Metabolic Rate

Take into consideration your weight. Determine your purpose of this. Have you checked your BMi and be cautious if you have health conditions. If you are healthy then by all means but I wouldn't suggest less than 1000 calories as you are working out too. As being underweight and limiting your calories with exercise can make you sick. Get your basal metabolic rate. Always get an expert opinion. So consult your Dr, nutritionist and pt

Calculate your basal metabolic rate. That is the only thing you need to know.

Yes. It sounds good.
