I hit my protein target without tracking food using my simple ‘4/5’ rule. It has helped me maintain my 35-pound weight loss for 6 years and build muscle.

My “rule” is flexible in practice.

For example, if I’ve had a simple vegetable pasta dish for dinner, I might have a high-protein yogurt rather than some chocolate for dessert. If I know I’m going to have a dessert that’s tasty but lacking in protein, I aim to have a high-protein afternoon snack.

“Ensuring that at least four out of your five meals include protein is a simple but effective strategy,” Ludlam-Raine said.

It’s not a hard and fast rule and I certainly don’t stress if some days fewer meals are high-protein, but generally, it works for me. Some days my protein intake will be higher, some days lower, but it evens out.

As someone who’s always been interested in nutrition and has tracked my protein intake in the past, I know what foods are a good source of protein. I try to eat meals and snacks containing at least 20 to 30 grams of protein: if I consume four of those most days, I’ll consume a decent amount overall.

Elite nutrition coach Mike Molloy previously told BI that he recommends consuming 0.75 grams of protein per pound of total body mass, or 1.6 grams per kilogram, for optimal health and performance. That means I’m aiming for around 110 grams of protein per day: three 30-gram meals plus one 20-gram snack hit that perfectly.

Flexibility means sustainability

Ludlam-Raine said that eating protein throughout the day helps with satiety, muscle maintenance, and overall health.

The 4/5 rule, she said, “allows flexibility and enjoyment, which is essential for maintaining a sustainable and healthy relationship with food.”

It’s important to be adaptable and not to stress about protein intake fluctuating, Ludlam-Raine said.

“Overall, it’s a sensible, relaxed approach that prioritizes protein without making it an overwhelming focus, which is something I often recommend to my clients,” she said.
