Here's an interesting and contentious one for you.
Which is better for healthy weight loss- pursuing a vegetarian diet or pursuing a high meat diet?
The challenges in front of the vegetarian are many- not just in food choice, but in the inevitable increase in calories per gram protein.
Fish, Chicken and other Poultry, have a massive percentage of protein per 100g, but that is not the important value here, it is grams protein per 100g per calorie. This I will go into below.
Staple Protein in a Veg diet (or at least my version of that diet) comes from Mushrooms, Beans, and Tofu.
Having recently switched across to attempt vegetarianism, I thought I should apply a little bit of statistics to see what would be better for me, considering my high level of excercise, and desire to lose weight(fat). I've chosen to ignore fat, as the levels in all these foods is very low.
So Here Goes.
Representing Fish is Cod (raw)
Representing Poultry is Chicken (raw)
Regular Tofu (raw)
White Mushrooms (raw)
Beans and other sprouting seeds are amalgamated and raw.
All data comes from here
So Per 100g of Chicken Breast:
(with Skin)
20.8g of protein and 172 cal- making it
0.12 g protein per 100g per calorie.
(without skin)
16.4g of protein and 78.1 cal-
0.21 g protein per 100g per calorie
Cod:
17.9g of protein and 82 calories-
0.21 g protein per 100g per calorie
Tofu:
8.1g of protein and 76 calories
0.10 g protein per 100g per calorie
Mushrooms:
3.1g of protein and 22 calories!
0.14 g protein per 100g per calorie
Beans(etc):
4.2g protein and 29 calories-
0.14 g protein per 100g per calorie
Tofu, despite undeniably being very healthy and full of other essential oils would require twice as many calories to catch up with the protein equivalent of chicken (without skin) or fish.
Mushrooms and beans show a good showing, and so if you're a vegetarian or a vegan- use them, not tofu, I guess. Also for you meat eaters, turkey is leaner and has a higher level of protein AND is cheaper than chicken in my local Sainsbury's- so is well worth a shout.
It seems therefore that prior to my triathlon I should switch to chicken and fish, or maybe try whey protein, which is unappealing!
Anyway, hope that helps.
