I'm going to agree with Synchro based on a small sample. my gf and I, she has stopped eating wheat and dropped several pounds in the last two weeks, I haven't and am about the same, my weight loss is from life without alcohol.
One major aspect of wheat based foods is that they are typically more calorically dense and a metric shitton more palatable than a paleo-style meal.
these two posts are highly related.
sugar and foods that digest like sugar have numerous neurochemical and hormonal repsonses in the body and one of those effects can be appetite stimulating, whereas paleo type foods tend to be appetite neutral. so the quickly digestable foods such as sugar and wheat/refined grains are hard to put down and even though you may be full the brain reponse is eat moar.
so while wheat on it's own is not necessarily bad and can be part of a healthy diet, it may be worthwhile to examine your overall eating patterns and how you are ingesting wheat products. at the end of the day we can still enjoy our fav foods, but watch the quantities you're taking in.
two other tips:
1. if you're going to have that treat, whether it be bread, pasta, cake, etc make sure it's very enjoyable so you make the most of those calories.
2. food timing can make a big difference as well and two of the best times to take in carb calories are in the mornings and after a workout - google the carbohydrate window.
finally , one thing to keep in mind is that while we have good ideas about how our bodies respond to food, food science is still evolving and that we don't all respond the same way to food. in general a diet based on a wide balance of fresh whole foods will serve you well.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
