Three signals for controlled muscle gain
Building mass is not about eating as much as possible. A gradual surplus, enough protein and consistent training help you understand what works for you.
Consistent protein
Spread protein sources throughout the day to support recovery and muscle development.
A measurable trend
Track several weeks rather than one weigh-in, then adjust intake if progress moves away from your goal.

Frequently asked questions
What to know before a muscle-gain phase
Simple answers about calorie surplus, protein, tracking and physical activity.
There is no universal surplus. Start with an estimate of your maintenance calories, increase gradually, then observe your weight and performance for several weeks before adjusting.
The pace depends on your experience, body and training. Gradual progress generally makes changes easier to control. A professional can help define an appropriate pace.
Needs vary with body weight, activity and goals. The important part is meeting a consistent intake and spreading it across the day. Ask a registered dietitian if you are unsure.
No. Occasionally weighing certain foods can help you understand portions. Ember also lets you photograph or describe meals for a quick estimate and consistent tracking.
Yes. Ember is free to start and includes up to two AI analyses per day. Premium unlocks unlimited analyses and other features.
A calorie surplus alone does not automatically direct energy towards muscle. Progressive resistance training provides the stimulus needed for muscle development.
Speak to a healthcare professional or registered dietitian if you struggle to gain weight, have a chronic condition, take medication, experience digestive issues or have a history of eating disorders.
