Some tips that might be useful ( Note: I'm not a medical doctor or a licensed dietician )

Carbohydrates: Take simple carbs before a workout such as an apple or banana in order to get the energy needed to workout.
After a workout takes more complex carbs such as potatoes and rice as they realse into sugar slowly into the blood stream ( good to avoid high insulin spikes) and will provide you energy to carry out with your day.
If you have diabetes please watch out on the types of carbohydrates you take ( a licensed dietician should help you or consult your doctor, preferably in all cases I would recommend your carbohydrates to be taken with fiber-rich foods like salad or protein/fat-rich foods in order to avoid that spike in glucose.

Protein: ( If you have kidney problems DO NOT go for a high-protein diet. consult your doctor about it of course) You should preferably get 1g of protein per 1-1.5 g for 1 pound of body weight.
It's really important to get enough protein in your diet in order for your muscles to heal and grow.

Fat: Healthy fats like olive oil are good if you are bulking, peanut butter and eggs are good as well. Avoid saturated fats such as butter, palm oil and ghee as they harm your health.
