I am a little confused because both of these actions should make you gain weight, not lose it. I don't know how much you weight, but either eating a healthy diet or eating less should help with losing weight.
However, I would still suggest exercising which is almost always healthy. Although it will gain you muscle mass it will burn unhealthy mass and fats.
You need to read some books about nutrition so you know how to eat right. Protein shakes are made of powdered milk, soy flour, sugar, and flavor. They cost about $1.25 for the amount of protein you get in a quarter's worth of milk. Your body needs 4/10 gram of complete protein per pound of weight, about 65 grams for a female and 90 grams for a male. You do not need more because you exercise or less because you loaf. For convenience you only count 6 grams per egg, 12 grams per glass of milk, and 24 grams per quarter pound of meat. If you eat more than the body needs, the excess is burned as ordinary but expensive calories. If you really think you need more protein, get powdered milk and mix it into your food. Eat veggies with every meal, or whole grain bread every day, to keep your bowel movements regular.
Fat is made of carbon and hydrogen. The only way it comes out of the body is if it is turned into carbon dioxide and water and then it comes out through the lungs. So that involves a lot of heavy breathing, and that means jogging or aerobic dancing. Figure on losing one pound per week when you are doing things right.
