Pre and Post Workout Nutrition
Over the years in my experience of coaching clients as a personal trainer it is clear there is much confusion or lack of understanding around what people should eat pre and post work out. From working with many male and female clients of all age ranges with different fitness goals this is my best advice for maximising the efficiency of a training session from your pre-workout meals and boosting recovery from a workout in your post-workout meals.
By following these guidelines you can expect to experience
Increased fat burning
Inhibition of fat gain
Decreased inflammation
Increased ability to build muscle
Improve immune function
Improve bone mass
These benefits seem to work for everyone, regardless of gender or age.
Pre workout nutrition
If your goal for training is based around fat loss then the optimal time to train is first thing in the morning. This is due to an overnight fasted state where blood glucose levels will be low. This state optimises the body’s effectiveness at utilising fat for energy.
If you are unable to train at this time then a perfect pre workout meal should be eaten 2-3 hours prior to the planned exercise session and should mostly consist of protein and fat. A good example of a meal here would be grilled chicken breast and avocado salad seasoned with Himalayan rock salt and fresh lemon and olive oil.
Studies have shown that consuming caffeine 30minutes prior to a workout can boost energy and also improve the fat burning effect during exercise. Other foods to consider prior to a fat burning session are cacao and green tea again both linked to improving the body’s ability to utilize fat stores for energy.
Other popular training goals include performance training and muscle building.
Pre workout nutrition for these training goals is very different. The idea with the pre work out meal here is to prime the body to maximize effectiveness of the session. This is linked to the effect it has on important hormones most notably testosterone and growth hormone. A meal with low GI carbs and a good protein source about 2 hours prior to training is optimal. The list below shows a few examples of some good pre workout meals when your goals are performance or muscle building based.
Pre-workout meal ideas
Oats with protein powder. Probably the perfect pre-workout meal, oatmeal with protein powder will give you both short and long-term energy to power through your workout.
Protein of your choice, sweet potato and broccoli. Perfect combination and ratio of low GI carbohydrates and good protein – primes the body for an effective workout.
Post-workout nutrition
By consuming particular nutrients after your workouts (aka post workout nutrition), you improve your body composition, performance, and overall recovery.
Generally, post-workout nutrition has three specific purposes:
replenish energy stores
increase muscle size and/or muscle quality
repair any damage caused by the workout
What to eat
Post-workout nutrition requires two things:
Protein to aid in protein synthesis
Carbohydrates to help replace muscle glycogen
You can either make your own post-workout drink or find a pre-formulated drink that contains rapidly digesting carbohydrates (e.g., maltodextrin, dextrose, glucose, etc) and proteins (e.g., protein hydrolysates or isolates).
