You cannot out train a bad diet, and Larry Wasserman says it as somebody who tried. He is a personal trainer who used to believe he could eat whatever he wanted as long as he was working out, and the post explaining why that stopped being true is the honest centre of the blog.
His practical writing is about sugar. A simple way to convert carbohydrates into the sugar figure that actually matters. What sucralose is and why the marketing language around it is designed to confuse. A month long challenge to go without sugar entirely.
The piece on hiring a fat loss coach is the one to read before you pay anybody, because it lists what to ask rather than what to look for.
His business posts are shorter and mostly about attention, including a straight refusal of every shiny new thing that appears.
Read the diet post first if you train hard and nothing is changing.
