Is eating strictly 800 calories a day bad for you

If you're 4'8", then 800 cal/day is reasonable.
Otherwise, no.

You're probably eating more than you think.
Weigh &/or measure your foods, until you have a good eye for estimating.
Record everything. Make your diary private, but you have to be honest with yourself & have good data.

Include some healthy fats (nuts, avocado, salmon).
Dip your baby carrots in hummus.
You could pretty much have unlimited veggies, close to unlimited fruits, and a serving of whole grain & protein & still lose weight.

Play around with your diary, entering various foods you LIKE & seeing how they come out in calories.
I love peanut butter, but it's got 100 cal/T, so I have some on toast for breakfast instead of 3 thick PBJ sandwiches for dinner.
Make a big pot of vegetable barley soup. Throw in chopped-up leftover pot roast if you feel like it. Or a can of beans. Very healthy, very low-cal.

I'm 4'11 and was just put on an 800 calorie a day diet plus prescribed phentermine today by my endroconolgist. If your short like me 800 is ideal to lose weight and 1200 to maintain after you reach your goal. If your average height id say 1200 is the lowest you should go.

Gee, that's such a good list. I wish I'd thought of it.

You did. It was a quoting error on the posters behalf. I never posted the list or even had anything to do with it, nor did I claim I had anything to do with it @diannethegeek

Michael Mosley says 800 cals per day is doable but only for 8 weeks. It is called (I think) The Fast Beach Diet. I do his 5:2 way of life and have lost 15kgs. I have 500 cals or less twice a week. I have lapsed now and again and sometimes had as much as 800 cals but I still call that a fast and have on occasions only done one fast a week so my weight loss has been slow. I, like most folk, love food, think food, dream food, find comfort in food grrrrr. But Im getting there thanks to the MFP app
