"This is the worst week ever, I'm not normally this bad" - we heard this a lot!
What we found to be the most common deficiency was a lack of VEGETABLES and too many simple carbs and unhealthy fats. By religiously keeping your food diary (written down) you can keep track of what you are putting into your stomach and work towards adding as many coloured vegetables as you possibly can into your day, and putting PROTEIN (the muscle building block) into every snack & meal you take.
Look at including only primo fats into your engine, ie olive oil, flaxseed oil, avocado (1 quarter of an avo, is a far healthier option to smear on your toast in place of butter, which is a saturated fat & not condusive to a healthy heart.
WATER WATER WATER !!!!! Those of you who are still meeting the barre, train yourself to sip water continuously throughout your day, you need to get to the 2 LITRE mark urgently!
