Bah, why do people write such painfully long posts without an executive summary at the top?
Here's the executive summary:
1. Do not eat more calories than you need. 2. Exercise 3 times a week (or more if you have time and enjoy it), with moderate intensity 3. Ensure that most of your meals follow a good macro nutrient profile (but if you have to cut something, do it in carbs --> fat --> protein order)
Not sure why people have such difficulty grasping those concepts and will come up with statistically irrelevant anecdotes in futile attempts to prove the main concepts wrong.
