@shaunf Just for any bystanders tuning in, I'll add that the
1 g per lb bodyweight rule is grandly overstated and has been proven such through research. You can definitely eat that much if you want -- maybe you love whatever protein sources you're eating from or utilizing a higher intake for satiety reasons -- but it won't have any benefit as far as building muscle and increasing strength is concerned. Even on a deficit, you only need at most
1.8 g per kg body weight or 0.82 g/lb.
This has also been cited as a very safe value, meaning that it takes all extenuating circumstances into account.

Really, there hasn't been shown to be any value in getting more than
1.7 g/kg or
0.77 g/lb. Science considers this to be a very high-protein diet to the extent that overfeeding (eating in a surplus for bulking, for example) would generally not directly contribute to fat mass.
That said, similar experiments went as high as
2.2 g/kg or otherwise known as the infamous
1g/lb bodyweight rule, and didn't see any additional benefit at all. The same experiment tested 2.4 g/kg out as well, and no dice.

The threshold for making gains starts at
1.6 g/kg or 0.73 g/lb and you can maintain between
1.2-1.4 g/kg or the equivalent
0.54-0.64 g/lb. The first source above actually saw advanced lifters gain both strength and muscle mass on as little as 0.55 g/lb.
So if you're finding it difficult to get protein, you don't need as much as many fitness enthusiasts may tell you. And you'll save a lot of money just hitting your minimums. For carb fanatics like me who want to leave as much room as possible for more euphoria-inducing foods, you'll also have a better time overall.
Not to mention, if gaining muscle or strength is your goal, filling out your diet with carbs after hitting your protein and fat minimums is what most professionals recommend due to the numerous anabolic/anti-catabolic effects of carbohydrates.
Here's a review of some recommendations put together by Andy Galpin, who has a PhD in Muscle Physiology. One of my favorite YouTubers - Mike Isratel of Renaissance Periodization - who is a competitive bodybuilder with a PhD in Sports Physiology is also a big supporter of his work. I generally keep this in my notes for fellow fitness-oriented folk who struggle with the more popular but outdated 1 g/lb rule recommendation.
