Sawatdee Khrup!
I am not a nutritional it's but did qualify at diploma in nutrition and have been supplementing my diet for 38 years so I hope I can add to this:
First we are all different (height, frame, weight etc) in addition our aims may be different, losing weight, gaining weight, lean muscle, stamina etc, so bear this in mind when taking protein and energy drinks, they are still food and therefore calories.
For me, what works ideally is keeping my carbohydrate meals in small portions several times through the day and a protein meal (no carbs) at night. I also keep my protein- carb ratio at about 80/20 (protein being the highest).
This diet allows regular glycogen (blood sugar) in my blood stream and keeps me energised throughout my training. Regarding protein and energy drinks; I supplement 1 x protein drink with breakfast I then take Relflex nutrition 'The Edge' which is a blend of protein, simple & complex carbs and electrolytes (an all in one if you like) I take this pre, during and after my workout. It is important to take carbs and protein within 45 mins of your training to ensure correct anabolism (growth and repair) and to avoid catabolism. I take 1x protein drink prior to bed to assist in recovery and repair.
As I said we are all different and nothing replaces quality food
Hope that helps airtime
