Wondering if there is anything I need to know first. So im married to a meat and potatoes kind of guy. I had been steadily losing 2 to 3 pounds a week. Thats started to tapper of. Im curious how not eating meat will do. So starting tomorrow im going to try to go 3 weeks without eating meat. I take a multi vitamin and may have a slimfast shake every day. Is there any other thing I need to introduce to my diet?
I used to be a Pescatarian (google it!). As far as I know cutting out meat isn't a big deal providing you're eating a good diet. You should be able to get all the protein you need from beans, pulses, nuts, eggs, & milk. The main thing to watch out for with the diet you describe is iron deficiency.
Now for a bit of background:
People will tell you that you can get plenty of iron from green leafy vegetables. This is true, but the iron you get from veg is "non-haem iron" and is harder for your body to absorb than haem-iron, which is the iron you get in meat. Thankfully there is something you can do to help your body absorb non-haem iron and that is to ensure that there is vitamin c in you gut at the same time as the non-haem iron. The easiest way to do this is to have a glass of Orange Juice with your meal whenever your eat green leafy veg.
Hope thats useful :)
Like David says, if your diet is good, dropping meat out should be fine. Meatcis protein rich, do replace that as people h a ve suggested. Be sure your multi vitamin gives you iron sbd b-12 (found mostly in meats but also in dairy). The other thing i would suggest is making sure you go beyond salad for veggies - both b/c many salads arent that nutritionaly dense and also because you may get sick of them :).
