More than Just Calorie Restriction



I am most certainly not an advocate of counting calories, or diets that revolve around creating caloric deficits through either eating less or exercising more to achieve weight loss.
A few points on calorie restriction:
It is not entirely wrong, the principle that if you consume less than you expend and create a deficit then you can lose weight, however there is a threshold on what that deficit should be, too much of a deficit will lead to low Leptin (the starvation hormone) levels and put the body in to a starvation mode, use muscle mass for energy, slow down metabolic rate and store whatever food one does eat as fat to produce more Leptin in the fat cells. So to simply not eat much, be hungry and try to expend energy through exercising (eat less, move more approach) is in fact an unhealthy weight loss, not necessarily fat that is lost but more bone and muscle, and can ultimately result in further weight gain as it teaches the body to react to famine by not expending as much energy and storing energy when it can.
But what makes one believe that for every man, no matter how tall they are, or heavy they are, or muscular or skinny… that all adult males require a daily intake of 2,500 calories. Why is 2.500 calories the mark for everyone? Surely the amount of food we need per day in order to function properly would vary from person to person based on a lot more variables rather than just age and gender and activity level, and that we have moved beyond this view that one size fits all.
It DOES matter entirely, where those calories come from. If it were only a question of excess calories, then people could live on 2-3 mars bars a day and lose fat.
Studies have shown that people who go on diets such as Atkins or Paleo, diets that don’t ask you to count calories, but to avoid carbohydrates, all processed foods and do not allow any sweets and focus on eating only the right things and as much as you like, were found to in fact not be consuming excessive amounts of calories even though they feel like they are eating lots of food and are not hungry. [i]
If 100 grams of Rump steak contains 125 calories, you could in theory eat 10 a day and only have consumed 1,250 calories. Or a 100-gram skinless chicken breast at 116 calories, you could theoretically eat 10 chicken breasts a day and only have consumed 116 calories.
If you ate the above then you would not only be full, the protein would be used for growth and repair and any excess would be used for energy, but you wouldn’t eat that much without eating vegetables too, dark green ones, the ones that are very low calorie but extremely high in micro nutrients, like spinach or broccoli for example, which contain practically no calories at all, 100-grams of spinach contains 24 calories. You could consume more than half a kilo in spinach a day and it would only have added 120 calories.
If you ate in a similar manner to what I’ve described above then you would find that you would be constantly full, due to the fact that protein suppresses hunger too, and you would probably not even get through 10 fillets of chicken or steak for that matter, probably only 4-5 would do.
The point is that you are feeding your body things that it needs, which will contribute towards developing lean mass, which will also speed up metabolism, your carbohydrates are restricted so you are keeping insulin levels low, and therefore allowing for triglycerides to move in and out from the adipose tissue (allowing fat stores to be mobilized for energy) through the pancreas’s secretion of the hormone Glucagon which converts fat into energy.
So the way that many people who go on calorie restricted diets do it, is to go to the supermarket and buy processed foods and read on the back of the packet how many calories are in it. When you should really be eating foods that do not have labels at all, and get things from over the counter at the butchers, fishmongers and the vegetable aisle, you can pretty much forget the rest of the supermarket.
Which concludes essentially with the point that if you eat the right things, there is no need to count calories, as I have shown above, it is very difficult to exceed 2,500 calories per day when you are eating these foods alone. If you then start adding in products such as a baguette, that’s 240 calories roughly in itself, or a can of coke contains 142 calories, or 100-grams of penne pasta contains 352 calories, these are the foods that not only have little nutritional value but are filling us up with empty calories, if our diets include these things, which they do for most people it is not very difficult to consume excess calories. With these foods present as staples of ones diet another needed measure is introduced which one on such a diet is constantly in need of monitoring called ‘portion control.’
It is not that I disagree with the principles of calorie restriction, but I am more concerned with my clients eating the right things, as opposed to them reporting to me that they ate a go ahead cereal bar, a piece of fruit, a weight watchers biscuit, a chicken salad sandwich on brown bread, a small low fat yogurt and some whole grain toast.
Which sounds politically correct and healthy, however in reality it’s not, there is not enough protein or vegetables and is full of refined starch and sugars, but to the public it sounds healthy, because it includes words like ‘Go ahead’, ‘Fruit’, ‘Weight watchers’, ‘Salad’, ‘Brown bread’, ‘low fat’ and ‘whole grain’.
The above is in fact a disaster diet, promoting insulin resistance, loss of lean mass, hunger throughout the day and promoting weight gain when one comes off the diet, referred to as yo-yo dieting.
Calories are certainly not all created equally, carbohydrates are not equal to protein calories or fat calories for that matter. They are not all just energy, carbohydrates alone are only used for energy, whereas protein and fats serve other essential bodily functions first and only then in excess can be used for energy when needed, fats and proteins are essential, hence why we have essential fatty acids and amino acids which we must obtain from food, there are no essential carbohydrates.
A diet must address macronutrient and micro nutrient needs, and this must be achieved through choosing high quality foods that have a high nutrient content, low glycemic load and low calorie content.
So for example, to argue that oranges contain a high amount of vitamin C, does not justify eating oranges every day, oranges also have a high fructose content and are not the best source of Vitamin C available, a kiwi however would be a better choice than an orange. In fact Vitamin C need not be obtained from fruit at all, an even better choice would be from vegetables such as broccoli, kale, bell peppers or brussels sprouts.

This just proves that what I have been saying the whole time, eat right and get results, eat processed junk and look like you do.  TRAIN WITH WAYNE
