Full Answer:
Trying an all protein diet may help to jumpstart weight loss or be a good short-term solution to get a high amount of protein; however, it may not be a sustainable diet for the long-term. Sticking to a high protein diet will be a better option. By eating only protein, you are missing out on other macronutrients including fats and carbohydrates.
Protein helps to increase the feeling of being full and increases the metabolism during digestion. By eating an all protein diet you will be more likely to decrease gut fat that is a result of excess carbohydrates. The protein will also help to rebuild muscle that has broken down from exercise.
The best high protein foods include: lean meats, seafood, beans, soy, low-fat dairy, eggs, nuts and seeds. The best way to eat a high protein diet is to rotate the different high protein foods that you eat. By getting a variety of lean red meat, fish, beans, etc you will ensure that you are getting the extra benefits of each food.
Alternatives to and all protein diet
Instead of eating an all protein diet, it is recommended to use a low glycemic diet for weight loss. Aim for 25% of your daily calories to be from protein and 25%-30% of your daily calories to be from fat. A low glycemic food refers to a food that does not raise the blood sugar levels after consumption.
Pairing a high protein diet with exercise is imperative for losing weight. By increasing the protein in your diet with at least 5 days of cardio in a week with 2 days of resistance training, saw greater body composition development than those who only increased the amount of protein in their diet. If you are not planning on adding exercise, eating a high protein diet is better than not. If you incorporate a high protein diet you must increase your water intake to at least 8 glasses of water a day to help with digestion.
