In my opinion, your diet is possibly one of the most important things in your life and if it isn't, it should be. It's something that is entirely down to you and one thing you can have complete control over. You are what you eat after all and what you put into your body affects what you get out of it in your training and in your life.
A lot of people who want to get fit and healthy will find a plan, start exercising and then try to eat healthy by making drastic cuts to their diet. Although there is some sense in cutting back on certain foods, it can actually work against you, especially when starting an intensive exercise programme.
Your body needs a little bit of everything to function at its optimum level. Protein, carbohydrates and fats are all key components that make up a healthy diet. The solution is to get the balance right.
If you cut out carbs and fats and then start exercising five times per week, odds are you won't have enough energy to do the work and you're more likely to quit after a week or so.
The best thing to do when starting any kind of exercise programme is to make sure you eat well. Your body needs fat, it needs carbohydrates and as long as you're getting them from the right sources, it's fine. For example, pasta is a well known source of carbohydrate but so is broccoli, which is better for you and counts as 1 of your 5 a day.
Bacon is ok as long as you don't have 12 stacks of it, natural sugar can be found in most fruits and a pinch of salt and pepper never hurt anybody.
I hope this helps to disperse any myths about nutrition and what you can and can't eat. Eat well and train hard.
