Is this healthy?

So I really wanted a muffin today. But the muffins my boyfriend buys are blueberry (350 cals) and banana walnut (450). I am not a fan of bluberry muffins so I went with the mm mmm delicious walnut. Since it is full of cals/fat/sugar i decided to break it into quarters and eat it through out the morning. But All I have had (and its 3:30pm now) is that one muffin and an apple. Then I plan on having healthy choice vegetable soup for dinner with a salad. I have in my head that this is perfectly okay since I had an 1800 calorie day yesterday with a sushi dinner with ice cream after (strawberry yogurt haagen dazs in a waffle cone!!!). This is okay to do once in a while right???

Whichever way you cut it, muffins are a cake.... Cakes are not, never were and never will be the last word in health food.   Is it OK to eat a cake every so often?  Yes?  Just not all the time.

Those darn muffins fool me for breakfast foooood! But just today =P

Oatmeal tomorrow. I have been in an eating funk and I need to get back on track of eating healthy small meals throughout the day. Yesterday was an eat breakfast, have one apple, then have a big sushi dinner + haagen dasz! But i rarely eat ice cream as well (twice a month).

It's calories in, calories out so whatever you eat is fine.  Keep it in your limit and you're good to go.  Certain foods just provide what your body needs to make you perform/function better.  

what the fact that you had under 1,ooo calories or the 450 muffin.
i guess either one will not be so bad if its only one day.. it will average out.

I'm pretty sure having 800 calories or something along those lines is not really the best thing to do, especially since your muffin was probably mostly all fat and had very little nutritional vlaue, dont get me wrong, I indulge too but when i do i still manage to get my nutrients in. don't overcompensate by restricting your calories to next to nothing. calories in - calories out, just because you have a muffin doesn't mean you shouldn't eat much for the rest of the day. just my opinion. great job though on eating what you ACTUALLY WANTED and not choosing the lower calorie blueberry muffin that you wouldn't have enjoyed as much, many times people forget to eat what they actually like and choose what they think they should instead. so congrats !! :)

It should be okay to allow oneself a little treat on the occasion, so long as it isn't anything absolutely horrific (like eating an entire cake or something). Just watch out and try to curtail the excessive.

If you reallllly love muffins (I myself am a fan) try making your own with things like oats, and flax, and chopped up whatnot. There are a few good recipes floating out there, and you can add in all sorts of stuff (like sweetening with apple sauce, adding shredded carrot or zucchini, mixing in chopped figs or dates). If you make your own muffins, you can decide the size and the content, which would of course affect the nutritional value. Muffins can actually be made into a nutritional powerhouse.

I hope you plan to also eat a lunch, not just a dinner.
