This type of advice usually ends up with the person failing, not getting the results they want, then they get upset and things progress in the wrong direction. I feel it is better to have a understanding and outline of things rather then to do guess work and just think they are having balanced meal. Better to know exactly what you're eating then assume you know. Most people who want to lose fat didn't get there by on purposely bulking.
.
I may take it for granted that because I got a better then average knowledge on nutrtion that I can eat this way and it works. So someone whos new to dieting and nutrition may need a more regimented method.
On the contrary though I have seen people fail using calorie counting and succeed with a far more basic approach.
Fat loss is using more calories then you consume (though there have been studys that have shown certain types of calories(sugars)to have a drug like effect on the body)
So if one can figure out how to eat without overeating and eat a balanced diet doing that can bring great results
For example
take a person who whats to loose fat
this is there current diet
breakfast
2rashers of bacon, 2 sauages, 2 eggs, 2 slices of butterd white toast and a large coffee
lunch
cheese and ham baggette with a pack of crisps,jam donut and a sprite
snack:crisps and jellybabies
dinner:fried chicken with buttered mash potatoes, coldslaw, and a choclate mouse for dessert
night time movie snack: choc cookie and full milk
Now if that person was to then eat balnced meals without overeating
E,g
breakfast - 2 slices of eziekal/burgan bread toast, 3 scrambled eggs made with low fat cheese, 1 pint of water and some fruit
lunch - pasta with chicken and Pomodoro sauce and some blueberries for dessert
snack - mixed nuts and rasins
Dinner - salmon, sweet potato and a salad
night -snack - 1slice of bugen/ezekial toast with a organic peanut butter with no sugar and a glass of semi skimmed milk
Now with the 2nd meal plan all they have done is eat more balanced meals/snacks and controlled there portion size (e.g not eat masses of pasta for lunch or loads of rasins as there snack) and by doing that they have reduced calories, eating more balanced and will loose weight without having to worry about calorie counting.
