I'm naturally petite, and that paired with a healthy lifestyle and regular, rather gentle walking and hiking has meant I have never worried about my weight. I was a vegetarian for 12 years before starting to eat meat again. Once I started eating meat I did not notice any change in weight, but I was only eating it occasionally. Since starting to eat mostly Paleo, or rather I should say in cutting out grains (I was gluten free before this and only eating quinoa, brown rice, and mostly "healthy" grains) I have noticed a huge change in how I look (I look thick and heavy) and have gained 5lbs. I am not eating drastically different other than eating meat more frequently and protein more frequently.
Do I need to be exercising more with all this added protein/meat... any ideas how eating mostly Paleo could lead to weight gain?
FYI I am nearly 100% sugar and dairy free and 100% organic and have been prior to Paleo. Only thing that has changed is now low-grain, more meat/eggs/fish and probably a bit more fat from butter/ghee/coconut oil.
NOTE: I'm not concerned with being/looking thin but rather wondering why my shape has literally changed in a months time to one I have never had before. I have had phases of eating tons of raw milk, butter, organic ice cream and other fatty/high calorie foods and then phases of juicing/raw food and have done a 30 day juice fast and I have always retained the same shape and weight regardless. So I wonder if there is something happening hormonally due to the increased meat consumption/decreased grain consumption that is literally shifting my body shape....
