Despite what you hear on social media, there’s no one-size-fits-all protein recommendation, because your needs will vary depending on your age, sex, activity level, and health status. For most people, a good starting minimum ranges from 0.8 to 1.0 grams of protein per kg of body weight. For someone trying to lose weight, a good guideline is at least 1 gram of protein per kg of body weight.
You’ve likely also heard the WeightWatchers advice to get as much of your protein from whole foods as possible — which is great whenever you can! But you’re probably not tossing high-protein foods like a hardboiled egg into your tote bag for a long day on the go. That’s where protein bars enter the chat as a solid backup plan.
We sampled lots and lots of bars to find the right balance of protein, texture, and taste. Our chief nutrition officer Michelle Cardel, M.S., RD, Ph.D., who finds many protein bars gritty and unappealing, loved the flavor of the Rx Bar in Chocolate Sea Salt. So did our head of program and food Laura Weissbart, who kept reaching for them long after the evaluation period ended thanks to their rich, chocolatey taste and 12 grams of protein per bar.
Let's just say you shouldn't leave one of these unattended in the WW office fridge.
