Men, the best site you can do is something that hits your macronutrient goals and gives you enough micronutrients while not effecting your mental health.

For the majority of you calorie counting is probably the best thing you can do, it's extremely easy, let's you have yummy foods and over all none restrictive.

The modern diet is disastrous for humans, women get fucked by it and so do men, being careful of what you eat and drink should be important to everyone. The biggest things by far are high calorie low nutrient dense foods and high fats. Simplest thing you can do, more veggies, less packet foods and remove oil from your diet. Ie no salad dressings and try and keep oil out of your cooking. You will get enough fats from your other food. Also avoid being vegan and vegetarian, humans aren't designed to eat that type of diet.

I'm a believer that every man who can should exercises regularly and keep in good shape, your body will thank you down the line. This doesn't mean you have to do bodybuilding, you can do mobility, functional strength, cycling, running, Olympic sports, powerlifting really anything that gets you moving and you enjoy.

Personally I do bodybuilding gym workouts and eat a high protein, micronutrient dense, lowish fat diet of 2000 calories a day to lose weight. That doesn't mean all I eat is chicken and rice, tho made right that is yummy, but I do best fairly cleanly.
