The reasons why obesity is such an epidemic is... 1) people don't exercise 2) our carb heavy diet 3) excess sugar and salt. Intermittent Fasting helps because it increases HGH while decreasing insulin. Also, for men you can naturally increase testosterone thru IF. A study was recently done that showed that many men under 30 have low testosterone. This is because of our diets are heavy in carbs. Put away the bread. Eat more steak, whole eggs and butter.
Meh, I used to think sugar was the devil, but I've changed my tune over time. I eat a LOT of junk food, but I also tend to balance it out with (1) healthy meals, and (2) healthier versions of treats. Even if it's just making desserts at home (like peanut butter cookies - PB, sugar, vanilla, egg). I make a lot of treats with protein powder too:

And of course, energy bites are awesome:

I also eat a truckload of salt & I'm not currently super-active. But that's not really the point...the point is energy balance - under-eating for your body, eating at the right level to maintain, or over-eating. If you haven't seen it, check out the documentary Fathead...it's one of the things that really cemented that it all boils down to eating too many calories for your body as the root cause of obesity, not specific food or ingredients:

As long as you keep your calories at or below your body's daily requirements, you will maintain or lose weight (unless you have some kind of underlying health issue that needs to be addressed otherwise!). Check out this article on a dude who did the Twinkie diet for a month:

TL;DR - find out your TDEE (your body's specific daily calorie requirement) using a TDEE calculator & start tracking your calorie intake. You can live off Snickers bars & lose weight if you really want to. When I first started, I ate a lot of bland tuna, chicken, and plain frozen veggies. Now, half my diet is homemade cookies :biggrin:
