 Why am I not losing weight eating 800 calories a day?

Losing weight can sometimes be a stressful process and even worse if you do not see any difference. If you’ve taken the 800 calories diet plan, you expect to see results, but a few things could be frustrating you:

  • The idea of this strict diet plan is to lose weight by watching your calorie intake. Eating nutritious food is the goal, but that doesn’t allow you to eat unlimited amounts without consequences. This means you have to pay attention to the number of calories in food, adding up to 800 calories and nothing more. Since it’s a numbers game, you cannot afford to compromise.
  • You can also be trying to squeeze in exercises and sometimes go crazy to reach your goal faster. Sometimes, you can be miscalculating the calories you burn during an exercise; that’s why it seems like it’s not working. Furthermore, each person is different, and you might just be burning calories slower than other people might. To get the most accurate reading, wear a monitor to track your calories burned.
  • Also, if you’re eating out, there’s no sure way to know if your meal contains the right amount of calories. Even if the restaurant is keen on nutritional value, you can’t expect the kitchen crew to weigh and measure each ingredient for accuracy. Of course, you can’t avoid eating out altogether, but you can cook at home if you really want good results.
  • If you’re big on snacking, that can be your other problem. This is because the stated number of calories on the packaging isn’t always accurate. Sometimes the brands reduce the number to get you into thinking it’s perfectly okay. That way, you take in more calories than you should, and your weight increases instead of shedding.
  • Also, you could be overlooking the calories in your drinks. For instance, you could be taking a healthy glass of juice with around 165 calories. If not included in your initial numbers, you’ll be having more than 800 calories. If, by any chance, you have a few glasses during the day, well, you’ll be exceeding the 800 calories making it hard to lose weight.

Do you poop less when losing weight?

While you might feel lighter after you poop, you don’t actually lose any weight. Yes, you might poop less since you’re taking in less food. Most likely, you might get constipation that can be alleviated by taking in more vegetables.


Intermittent fasting sounds like a good idea, but you need to think it through carefully. Your body needs essential nutrients, and the dieting plan doesn’t allow work well with everyone. You might want to schedule a meeting with your nutritionist and ask if you can lose weight by eating 800 calories a day. Starving yourself can cause serious health issues, and you need to consider if that’s a risk you’re willing to take.
