How much protein did you have before lunch yesterday? If you started with coffee and toast, grabbed something light at midday and had most of your protein at dinner, you’re in good company. In a study of more than 10,000 adults, dinner was typically the most protein-rich meal, and breakfast often provided considerably less.
When I talk to women about eating to stay strong, breakfast is often where we start. Getting enough protein across the day comes first. Giving breakfast and lunch a meaningful share is a practical way to get there.
Why spreading out your protein can help
After you eat protein, your body breaks it down into amino acids. Your muscles use those amino acids to make new proteins, a process called muscle protein synthesis. Resistance training gives your muscles a reason to adapt, and eating protein at several meals gives them repeated opportunities to use those building blocks.
In one small controlled study, eight adults ate the same total amount of protein on two different schedules. On one schedule, they had roughly 30 g at each main meal. On the other, they had around 11 g at breakfast, 16 g at lunch and 63 g at dinner.

Even: about 30 g at each meal
Breakfast30 g
Lunch30 g
Dinner30 g
Skewed: most at dinner
~25%
Muscle protein synthesis rate was about 25% higher when protein was spread more evenly across the day – starting in the morning.
That measured how quickly muscle made new protein over a day. How much muscle someone gains over months is a separate question.
What researchers found in women
192 women, aged 18–79
In a study of 192 women aged 18–79, eating at least 25 g of protein in one or more periods of the day was associated with greater lean mass and better upper- and lower-body strength, even after researchers accounted for total protein intake and physical activity.
60 women, aged 65+
A separate study of 60 women aged 65 and over found that those who tended to eat a greater share of their protein at breakfast had higher skeletal muscle index and grip strength than those who favoured dinner.

There’s also early evidence that timing might matter beyond muscle. In the large US study, higher breakfast protein intake was associated with slightly lower blood pressure and higher HDL cholesterol. For everyday purposes, the clearest reason to start earlier is that it gives you another meal to work towards your protein goal.
What protein across the day can look like
If 90 g a day suits your needs, one way to get there is around 25 g at each main meal and 15 g in a snack. You can move those amounts around. Start with the meal that usually gives you the least protein. For many women I speak with, that’s breakfast.
= 90 g across the day
Two easy ways to make your usual breakfast more substantial:
1
Vanilla berry smoothie. Blend a 30 g serve of Gut + Protein with frozen strawberries, a handful of baby spinach and your usual milk. Gut + Protein contributes 22 g of protein before you count the other ingredients.
2
Vanilla yoghurt bowl. Stir Gut + Protein into plain Greek or lactose-free Greek yoghurt, add a splash of milk to loosen it, then top with strawberries. The yoghurt also contributes its own protein.

What Gut + Protein brings to breakfast
I formulated Vanilla Gut + Protein to bring together two things I wanted in my own morning routine: plant protein and prebiotic fibre. A 30 g serve delivers 22 g of pea and brown rice protein and over 2 g of leucine, an essential amino acid that helps signal muscle protein synthesis. The finished blend is Monash University Low FODMAP Certified, giving you a tested option if you look for low FODMAP products.

The prebiotic fibre is clinically studied Solnul® resistant potato starch. It reaches the large intestine, where gut microbes can use it. In a four-week placebo-controlled trial in healthy adults, researchers tested Solnul® daily and reproduced two earlier ingredient findings: a greater increase in the relative abundance of beneficial Bifidobacterium and more stools in the typical range for consistency.
If you already make a smoothie or reach for yoghurt in the morning, start there. A serve of Vanilla Gut + Protein adds 22 g of plant protein and prebiotic fibre to a breakfast you already enjoy.
