Bulk protein shakes went on sale and my trend line shrugged

I weigh every morning, but I only make decisions from the 7-day average. Yesterday the warehouse had a giant pack of 30g shakes on sale, so I grabbed two.

Had one after a short lift and another around 4pm when my brain wanted something crunchy. This morning the scale was up 1.6 lb, which is exactly the kind of blip I used to spiral over.

My trend line is still down 0.2 for the week, so I’m calling it sodium, extra volume, and a later dinner. The sale was a win; the number was just weather. For folks who also stock up when protein is cheap, how do you keep a good deal from becoming a daily obligation?

Ha, I had almost the same thing last month: two shakes on a lifting day, scale +1.4 the next morning, then back down by day 3. What helped me stop caring was comparing this week’s 7-day average to last week’s instead of today to yesterday. Also worth checking: were the shakes noticeably salty or carby? For me, a

I track cost per 30g protein and shipping speed, so I get the two-pack instinct. But every time I swap in pre-made shakes, my scale bumps 1–2 lb for a few days — they’re usually way more sodium/carbs than my powder, and liquid sits differently.

The 7-day average is the right filter. What are the sodium and carb numbers on these vs your usual?

Also check the label: I’ve grabbed a “30g” pack before and it was actually two servings, which explained the 4pm crunchy-craving math for me. I’d give it three mornings before touching anything.

Honestly, I’d push back a little on the 7-day average being your only decision-maker. When I add a new packaged food, I switch to watching a 14-day trend plus waist measurement, because sodium/carb shifts can keep a 7-day flopping around for a bit.

Two 30g shakes are ~60g protein; if they were stacked on top of your usual day, that’s also extra volume, and the 1.6 lb is likely noise. My

Not the shakes themselves, probably the liquid + sodium + extra carbs hitting around that second one. When I swap a solid meal for a shake, my 7-day line hangs 1–2 lb higher for a few days even at the same calories, while my waist doesn’t move.

I track weekly average waist and gym log alongside weight; if lifts are progressing and waist is flat, I ignore the blip. Question: did the 4pm shake replace a crunchy snack or stack on top?

That changes my read more than the sale did.

Do you log the shakes as “snack” or “protein” separately? I’d tag them for a week and compare the weekly median, not just the 7-day average—my scale gets dramatic whenever I add a new packaged food even if calories are similar.

Concrete check: are you replacing a crunchy snack or adding them on top of lift days? As a dorm budget person, I’ve learned “cheap protein” and “same eating pattern” are two different experiments.
