Energy balance is based upon dietary/caloric intake and metabolism. Healthy weight can be based on values based on height and weight, such as the body mass index (BMI).

No. Intake balanced with needs means to me that you are putting into your body the same amount of energy that you burn each day. There would be no storing of fat and no burning of fat. If you were exercising and gaining muscle you would actually gain weight. The only way I could see weight loss occurring while caloric needs were balanced with caloric intake would be if you became less active and had muscle atrophy while simultaneously realizing your reduced needs, thus reducing caloric intake accordingly. You would lose the muscle weight.
You gain weight because the excess calories get stored as fat deposits
Consuming excess calories from any source, including protein, can contribute to weight gain. Protein itself does not directly cause weight gain, but overeating protein-rich foods without accounting for caloric intake can lead to fat accumulation.
