The science of nutrition might be pretty complicated, but eating food is not.
Just eat real food.
Eat protein – at least 1g per kilo of your bodyweight every day.
Eat veggies – pretty much as many as you can cram in, of as many different types as you can manage.
Eat a portion of carbohydrates every day, especially if you’re active.
Allow most of your fat intake to come from whole food sources which also fit into another category.
Drink plenty of water.
Keep foods which don’t fall into any of the above categories (like processed food or alcohol) as a small part of your diet.
That’s it.
We don’t need to subscribe to diet ‘religions’. Optimum health and uncomplicated eating is found somewhere in the middle.
Of course there are some people this won’t be the right approach for, but for the vast majority of people trying to lose weight, this will get you off to a flying start.
