This is THE MOST IMPORTANT summary of THE MOST IMPORTANT issue regarding how we lose fat.
I believe this to be the absolute definitive answer of the most intense debate amongst the zealots of the health industry. In the weight loss industry there tends to be 2 types of people; those who count calories and those who promote quality of food and life. A line in sand has been drawn and an epic war of monumental proportion has evolved.
It is so easy to take sides. The reality is that both are important. Each of us has individual fuel efficiencies- Our metabolisms operate at different speeds dictated by genetics and hormones. People often forget that everyone is completely different. A deficit of calories for one person may be a surplus of food for another person. You MUST be in your own calorie deficit in order to lose weight.
Our calorie zealots fail to acknowledge that our own individual conditions of energy efficiencies can be changed. Now, we don’t know by how much, and we can’t exactly point a finger at exactly how. We can make assumptions that regular exercise and eating patterns, a low stress lifestyle, and consumption of nutritious foods can make a difference.
Hormonal ranges such as cortisol levels and thyroid output directly influence your metabolism. Over exercising, under-eating and not getting adequate sleep can down-regulate hormone levels (measured by lab ranges). In extreme circumstances hormones can down-regulate enough to result in diseases such as hypothyroidism.
Down-regulation of hormone levels means that your individual efficiencies- your metabolism can slow making it much harder to lose weight.
Next time you come across the battlefield of calories in/out vs food quality and lifestyle understand that they both have relevance.
