You can't say it's more trouble than it's worth because it's a sweeping generalisation, and different diets work better for different people.

Calorie restricted diet I have failed at many times before. Keto was difficult for the first month but now it's a doddle.

There's nothing wrong with carbohydrates either. Never said that. Carbs in moderation is a diet that most people I know seem to exist healthily and happily off. However elimination of carbohydrates is a tactic that's giving me awesome results, making me happy and more energetic. You do not need to consume carbohydrates to stay alive of be healthy.

Absolutely this. Everybody's body is different and respond in different ways. You have to work out what works for you.

I'll chime in with the former posters in favor of ketogenic diets. YMMV, but I personally find it much easier to stay on a ketogenic diet.

Check out the Applebee's menu (fairly typical): http://www.applebees.com/~/media/docs/applebees_nutritional_...

A 12 oz NY Strip + seasonal veggies will run you about 520-540 calories. That's under half as many calories as any of the fajitas, pasta dishes, and most of the salads. It's also half as many calories as any of the sandwiches.

It's bread and pasta that isn't worth it (unless you're poor and need lots of calories per dollar). The food pyramid makes people think bread is good for you, so people dramatically underestimate how many calories they take in from bread. A typical American diet might have two slices of toast at breakfast, two pieces of sandwich bread or a bagel at lunch, and a baked potato for dinner. These are simple accompaniments, not the stars of the meal, yet they add up to a staggering 700 calories daily. You could replace that with two slices of bacon at each meal and still cut your calorie intake substantially.
