I could recommend to you some of the hottest diets in the markets today, endorse some gym chain, or some home self-improvement product, but I would be a hypocrite. There is no such thing as a perfect diet. The reasons are simple and obvious.
Remember back when you were a kid in kinder garden to 3rd grade. Did anyone care about what body type you were back then? People made friends with you for who you were not what you were carrying or not carrying. Not what you looked like, but the type of person you were. That was the time when you developed real friendships but broke them because of choice, moving away, or changing schools. So obviously you can't go back to the past become that kid again. After all you are mature and wiser now.
What you can do is become even wiser and more mature to realize that what ever is making you feel fat, or thin or just plain bad inside is all in your head. It is true every one needs moderate exercise and a well portioned diet to stay healthy and live long, but now-a-days people are taking it to the extreme. Steroids, diet pills, exercise gimmicks make you feel that you can achieve what you assume to be the perfect body. But the fact is people of all sizes, shapes and weights are beautiful!
So why are we stupid enough to fall for these hazardous or money grubbing self improvement tricks? It is for the opposite sex. We feel that if we buy those diet pills, or that exercising machine, use steroids, we will make our self more attractive. But if there is no “self”, who will we be making more attractive?
That is what some of the diet pills do to us. They give us a momentary boost of confidence, or momentary self satisfaction. And when all this stuff stops working, we are more miserable than when we started out. The result, we buy even more or work harder. No one has it in them to return the equipment, because we will seem like losers. The people on TV got the results, how come, we can't? As for the question of sex appeal, there wouldn't be any sex appeal without the sex. Let me tell you that people of all body types have sex. They are all appealing. Maybe some shallow people only find the people with perfect abs or ripped chest sexually appealing. Next time some one tells you getting six pack abs and chiseled biceps will make you more attractive, you look them right in the eye and tell them that they are self pitying, narcissistic, unrealistic losers.
So we have established that there is no one body type that is the best. Now on to the issue of dieting, typically you should be able to eat what ever you want since there is no perfect body type. And you can, but in moderation. Not because you want to lose weight or gain weight, but because you want to live as long as you can. Excessively fatty foods do cause excess fat and heart problems. So eating a well proportioned meal will make you healthy.
As for exercising, it should also in moderation. You don't have to join expensive gyms or buy expensive home gym equipment. All it takes is parking your car a little farther, and walking to work that extra bit, or taking the stairs once in a while. When you find your self in a sedentary position for a long time, you can just get up and move around a bit. While watching TV, you don't have to sit, you can choose to do sit ups or push ups in moderation. Instead of eating out, cook your own food. Cooking burns calories and you know exactly what goes in your food. Instead of paying some one to mow your lawn or trim those hedges, do it your self. You will save money! Activities like cleaning out the garage or your own room and even sitting up instead of lying down while watching TV burns excess calories. So, exercise doesn't have to be a workout. It can be anything you want to do.
In conclusion, live, eat and exercise in moderation. Remember there is no perfect body type. All body types are beautiful. Also you can choose your own diet and exercise plan. It doesn't have to be expensive; it can be as simple as doing household chores.
