The question

Does eating protein at your first meal keep you full?

Short answer

Try starting your first meal with protein; many people feel fuller that way. Alan Aragon says what matters most is how much protein you eat by the end of the day, and that timing and spread rarely matter.

Does protein at your first meal keep you full?

Try starting your first meal with protein; many people feel fuller that way.

Benjamin Bikman says to focus on protein, and not to fear the fat that comes with it, because protein and fat together help you feel full.

Jessie Inchauspé says that if breakfast has little protein, your body keeps you hungry until it gets enough, so you are hungry again by mid-morning. She calls this a theory, the protein leverage hypothesis.

Treat these as ideas to try, not rules.

Do you need protein at every meal?

Get enough protein across the day, and a bit more as you get older. The daily total matters most; how you spread it rarely does, so do what's easy to keep up.

If you have kidney disease, ask your doctor before eating more protein.

Alan Aragon says what matters is how much protein you eat by the end of the day. Timing and spread rarely matter, so do what is easy to keep up.

These two sets of advice answer different questions: what to try at your first meal, and what counts over the whole day.

Who should ask a doctor first?

Ask your doctor first about protein if you have a kidney condition.

Alan Aragon says that for most people harm from a high-protein diet is rare. Existing chronic kidney disease is the exception, where he says it is not a good idea to push protein high. Even then, he calls it a trade-off.

If you take insulin or another diabetes medicine, are pregnant, or have had an eating disorder, don't set food rules without your doctor.

Where does Midline fit?

Midline's first level has a habit for it: try starting your first meal with protein. A later level has another: get enough protein across the day, and a bit more as you get older.
