0.25–0.5% a week
A small, steady surplus
Eat a few hundred calories over what you burn and gain about a quarter to half a percent of your body weight a week. That pace keeps more of the gain as muscle.
Iraki et al., Sports, 2019
You eat a lot.
Still not gaining?
Surplus counts what you really eat from a photo, texts you before you fall behind, and finds the big meal near you.

The method
No magic. The method that works, done for you.
Gaining comes down to three numbers. Surplus sets them for you and keeps you on them.
1.6 g per kg
Enough protein
About 1.6 g of protein per kg of body weight a day. In a 49-study analysis, more protein than that stopped adding muscle.
Morton et al., British Journal of Sports Medicine, 2018
7-day trend
The trend, not the scale
Your weight swings with water and food from day to day. Surplus reads the weekly trend and adjusts your target from that.

Built in public
You’re not buying an app. You’re joining the build.
Surplus is early, and I’m building it in the open. Every Believer gets a direct line to me over iMessage, sees what ships each week, and votes on what comes next.
The goal is simple: help you finally put on the weight you’ve been trying to gain. If Surplus isn’t doing that, I want to hear it first.
