I think this is a great cookbook for both fitness enthusiasts and bodybuilders! The recipes tend to focus on fresh ingredients, healthy fats, high-quality proteins, and are full of flavour. In general, the ingredient lists aren't too long, and are often things you might have on hand in a decently stocked kitchen (not including less 'mainstream' protein sources such as elk and ostrich).
If you are concerned about sugar in your diet, in general you could use a sugar substitute or decrease the amount you include in the recipe.
Each recipe has the nutritional information per serving. Some recipes seem to be calorically dense, but I find serving sizes to be pretty generous and you can also pick and choose your recipes accordingly.
There's also some great tips on what to stock your kitchen with, from kitchenware to seasonings and sauces.
Overall, I would definitely recommend this cookbook for those serious about good food and nutrition. Just remember that it is not meant to be a low-cal cookbook.
