Low Fat or Low Carb: How to Really Lose Weight : Health : Latinos Post. Here is another study about the relative benefits of low fat diets and low carb diets. The author posits that you can lose more weight on a low fat diet. However, in my experience, you lose more weight on the diet you can live with; and, for me, that has been low carb. A photo of myself in the ABA Journal article on Pets in the Law Office a couple of years ago got me started seriously, and, two years later, I am 100 pounds lighter; although, I am still heavier than I would like to be. I know, at our age, we should just be glad to be alive. But, I can speak from experience when I say that high fat foods tend to taste better, and I can't stand being on a diet that prohibits me from eating eggs, butter, red meat, and other things that I love. So, by all means, try both diets. Keep the one that works. But, don't read medical studies and be swayed by someone who isn't living your life. By the way, if you don't want a completely carb restricted diet, try the Paleo diet. Jeb Bush has lost 40 pounds on it, and looks great.
