My Wife is on a low calorie diet. I told her that increasing her protein intake would help to boost her metabolism.
I was wondering if ya’ll thought it would be worth ingesting an extra 220 calories a day for 40g/protein more?
Thanks.
Sure, try it and see.
how many calories is she eating now and what.
what is she doing activity wise.
That said yes I think it would help that and veggies and fruit. Many Many women serverly underfeed themselves on diets and would make better and usually faster proigress by upping the intake of GOOD foods.
Many American women do underfeed (and eat poorly) mostly due to a commercially induced need to look like… well the 90% of the images over there on the left. 
That being said…
I eat 1200 to 1300 calories per day.
That is not 1200 to 1300 calories of chicken nuggets and french fries.
I eat a well balanced diet with a lot of vegetables and fruits.
I don’t get as much exercise as I would like to but I also don’t sit on my ass on the couch in front of the TV all day.
Fibro and arthritis make a lot of workouts painful and when I’m up to dealing with it I do.
