losing weight is about calories in vs. calories out.... so it can't be good or bad for losing weight, you just have to account for it the calories in the falafel.
That being said, isnt falafel usually fried? oils are fats, more calorie dense, so be aware of that.
This. It's probably good every once in a while but not super often if you're counting calories.
You might not gain weight, but I'd definitely try to eat a baked one if you do eat it.
Falafels are made of 7 beans which are high in fibre. If you buy them frozen and make them yourself either baked or deep fried in a nonsaturated oil such as peanut oil or canola or vegetable oil combined with cabbage/carrot coleslaw filling on whole wheat pita bread they are good for you filling and guaranteed to shed the pounds. Foods rich in fibre such as cabbage, carrots, beans, grapefruit produce the melanin to burn fat cells.
Everything in moderation, will help you lose weight without going overboard (aka binging) :p
I make homemade falafel on a semi0regular basis and I always bake it instead of fry it. Then I take the leftovers (if there are any) and freeze them so I have ready-made falafel available when a random craving hits. Lately, I have been eating a falafel patty on a big salad, dressed with salsa and just a drizzle of tahini, which I find to be very filling and much healthier than fried falafel in a pita with all the sauces.
