600 calories a day is extreme…
Honestly, even 1200 a day is still very low - assuming you’re not a very very tiny person. You need to eat more.
Find a way to add at least one more meal. Extreme calorie defecit like that will lead to an unhealthy amount of weight loss, fatigue, weakened immune system, and a whole host of other health problems if you keep up your current lifestyle.
There’s nothing wrong with eating within a restricted window (intermittent fasting has huge health benefits actually). But, being in a caloric deficit does have consequences over time. You can Google them and find what’s applicable to you.
My suggestion would be consume more food (ideally foods that actually have nutrition value like vegetables, nuts, beans, healthy fats, whole grains, etc) during the time you have to eat. Essentially stuff your face :) just make sure it’s not total junk all the time.
I think it would be very harmful but I haven’t done any research to give you answers on why. But I’m sure a quick google search will help.On the top of my head your daily nutrition markers are not met so I’m sure you’ll end up malnourished and not able to function as well as you could. Next you could lose muscle mass I’m sure.
I think you could consider making smoothies and drinking them periodically.
Also depends how long ‘lately’ is. Is this a few days, or a few weeks? If a few days I wouldn’t worry as much since eating less for a couple days at a time won’t be harmful-just think about getting the flu and not feeling well enough to eat-but if it’s longer I would suggest getting more nutrient-dense calories. The issue here is that lowering food intake in not just decreasing energy intake but you’re also missing all the micronutrients you need.
I completely understand the stomach issues related to stress and would suggest trying to consume calories in liquid form to make it easier. Try a meal replacement like Carnation Breakfast Essentials or Ensure and see if you can sip slowely and get them down in an hour or two (or three or four if that’s what it takes). As a bonus there’s zero to minimal prep and they’re portable so you won’t add to your morning routine.
However, if this becomes a longer term issue and not just something that happens for a couple weeks it would be worth seeing a dietitian.
2200? Is quite a lot no? Unless you’re a dude. For women with average amount of exercise isn’t the recommended 1600? And if it’s short term I wouldn’t worry. Low calorie diets that go on for months is different from a couple of weeks.
If however it’s been well over 6 months then you’ll just gain back weight and put on a little extra when you go back to your normal calorie intake
Depends on activity levels and ultimately your hunger. If you’re truly under-nourishing your body will always ask for food. If you can make it through the day with this one meal, something tells me it’s just enough for you. The only risk will be nutrient deficiencies, and you could dodge that if your one meal includes a variety of plant foods.
