How many calories should I be eating?

Are you using a heart rate monitor?
During Insanity, I would average anywhere from 200-500 calories burned. Even with 30DS, my burns fluctuate daily.

Honestly with the amount of excercise you're doing, 1600+ should be your goal.

You need to log the exercise and eat the calories

I would keep your net intake at over 1000 - that's with exercise calories factored in, so you'll need to eat back some of your exercise calories. Your body needs nutrients to function properly, so don't let your net intake be too low.

I also highly recommend an HRM - I'm so glad I bought mine so I can accurately track my burns and know how much I should eat or how many calories I need to eat back.

Search for the thread titled in place of a roadmap. That explains it all.

Exercising so much and eating so little is hurting your body. When you don't consume enough you lose more muscle mass than you would if you do things properly. Muscle loss lowers your metabolism, hurts your organs and can cause injury.

Find out what your BMR is, find out what your TDEE is. Always net your BMR.

If you can't net more calories due to the amount of exercise you do, lay off the exercise.

Haven't gotten a heart rate monitor yet. Although I really want one especially while doing Insanity.

Thanks for the tip, I am going to try to adjust MFP to see where I should be at.

Givemewings ~ Can you tell me what you mean. Like if I burn off 1000 calories I should eat 1000 more calories?

My main goal is weight loss. I don't want to work my butt off exercising and not lose because of calories.

Oh sweetie, just spotted this - you must be so hungry! You are young and really active and need more fuel. The roadmap link I posted above will set you on the right path.

Hahaha! Thanks so much! Honestly, I am not that hungry! But since I don't have a lot of groceries I can probably use a little bit more each day! So happy it's payday!

I noticed after 3 days of the routine I was a bit more sluggish, so everyone's advice will really help me in reaching my goals.

Just a little back story - I did HCG and lost 50lbs, and basically ALL my muscle. Now I am working that much harder to gain those back plus lose the extra fat!

Out of curiosity why are you doing insanity AND the gym everyday? That is ALOT of exercise. if you like the the gym and insanity you could do 1 every other day (that is what I do 6 days a week) M W F I go to the gym and lift, T T S I do insanity. I am 5'2 158lbs and am eating 1700 a day doing this level of activity, you are doing more activity than me and alot taller so I would think you should be eating alot more than 1700 a day.

I just asked a similar question yesterday and had a LONG and very eye opening reply reg TDEE - I was way undereating and took the time to properly calculate out my TDEE - I now am at a readjusted 1600 a day as my loss stalled and I was way under eating - I suspect you might be the same - go here:

and read all that I learned - seriously I think your total per day has absolutely stalled your metabolism - you need to eat more to get the fat loss to happen...........

That link I attached is the post I put up yesterday and got so much info from it - hardest thing to wrap your head around is allowing yourself to eat and not feel guilty - there is a true science and logic when you undereat how your body stops the metabolism entirely to keep your body alive and working - it knows when it is not getting enough nutrition and is smart enough to essentially say ok, you gave me 1300 calories, I need AT LEAST that to keep your heart pumping and your brain working so I will stop other systems to do that - i.e. metabolism - I really encourage you all to read that post, print it like I did, go and calculate your military BF and then the TDEE - then less out anywhere from 10-30% off that # and THAT is calorie per day - you have to eat to make that metabolism move and burn and psychologically we all fear the higher calorie - don't - a friend on that post said to me seriously, eat and the weight loss will come.................

I switched to all plant based so no meat, no dairy and no oil as there is no nutritional value in any of that and it is loaded with fat and impacts health in so many ways - so I KNOW logically I am eating so amazing - and I need to say to myself it's ok, you are hungry for a snack, have the Wasa crispbread and organic peanut butter on it or have the fruit - it's that pychological bump in my mind that says too many calories but reality is, it is not too many, much of my stall for 2 weeks when you see my diary I was always UNDER 1200 - NOT GOOD!

Another friend of mine decided BRAVELY to do her actual TDEE at 2250 a day - WOW! - for 6-8 weeks to jump start the body and then she will less out a % ...................she noted it is a little scary but the logic behind it holds - and hey, if you go over a 100 no sweat - just eat well, small portions but at a higher calorie - hope this helps some of you as it really helped me yesterday and the amount of detail in the replies was exactly what I needed to read!

Totally agree with dixie! Gotta eat more!

I am doing both everyday. Well, that's was my goal...But I was only able to do gym AND insanity Monday/Wednesday this week and wasn't able to go to gym Tues/Thurs/Fri so it's not REALLY every day. But like last night when I couldn't go I biked 4 miles (20mins), and hula-hooped 20min.

Are you losing weight this way?

Honestly, I want to reach my goal within 2 - 3 months and I am just ready to reach my healthy BMI or feel healthy. I am not sure what exactly my goal is since I haven't been "fit" as an adult (YET). The previous diet I did that I lost a bunch of weight required under 1000 calories so I guess it is difficult to wrap my head around over 1500.

The days I did both I didn't really struggle with fatigue or anything.

1500 and that much exercising is still a drastic deficit, you'd probably have to eat 2500 calories to gain or maintain with your level of activity so if you can lose on 1500, instead of 1000 why not eat more?

I switched to all plant based so no meat, no dairy and no oil as there is no nutritional value in any of that and it is loaded with fat and impacts health in so many ways -

Where on earth have you got the idea that meat, dairy and fats have no nutritional value?
