One of the misconception about the Paleo diet is that it's all about protein and fat. What many don't realize is that by eliminating nutrient-void processed carbs I call them fillers we supplement with loads of vegetables, healthy fats, nuts, seeds, berries and fruit, all of which are full of minerals and vitamins.
Combine that with the improved gut health and increased nutrient absorption which happens through avoidance of irritating grains and legumes, and you get a very balanced diet. You'd be surprised that we can get pretty much all required nutrients from animal, seafood and plant based foods.
Most people experience weight loss and muscle growth while eating a paleo diet and keeping an active lifestyle. Improved metabolic processes and gut health, better sleep, stress management, sufficient Vitamin D and a healthy ratio of Omega-3/6 fatty acids all aid in burning off stored body fat.
