What it is
Body weight tends to increase when energy intake remains above expenditure. Gaining weight and gaining muscle are not the same outcome.
Why it matters
Simply adding calories does not guarantee where weight is gained. Food quality and the broader routine still matter.
Practical guidelines
- Begin with regular meals and review whether portions meet your needs.
- Add foods that contribute nutrients as well as energy, such as yogurt, beans, nuts or grains.
- Review changes gradually instead of trying to force rapid progress.
Common mistakes
- Expecting all additional weight to be muscle.
- Ignoring persistent appetite changes or unexplained weight loss.
Keep it simple
Use small, practical food additions. Unintentional weight loss deserves a conversation with a healthcare professional.
