GENETICS AND BODY FATS
Genetics can also influence how the fats are stored and burned in our body.
One recently conducted research tested several pairs of twins for 84 days, where one of the twins consumed 1.000 calories more than the normally required intake, making up for an excess of 84.000 calories for the same period. All the subjects had averagely passive lifestyle, without many physical activities.
Although the resulting average increase of bodyweight was 7.5 kilograms, the individual increase of bodyweight varied from 4.5 kilograms to 13 kilograms in different subjects. Although all the subjects had been eating exactly the same food, in exactly the same period of the day, and had the exact same lifestyle, the genetically doomed individuals showed an increase of their body weight 3 times higher, than the genetically blessed ones.
Not only that they stored 100% of the excess weight compared to the 40% stored by the blessed, but also experienced an increase of their waist fat deposits by 200%, unlike the “genetically blessed”, who experienced no increase whatsoever.
However, this should not be a cause for panic and despair. Although the facts presented here may seem frightening, the situation is not as black as it appears to be at first sight.
First of all, everyone of us has some genetic fault that calls for some attention. Some of us are predestined to have excess fats, others are fairly thin but have patches of stubborn fats, some have problem in gaining muscles, others are muscular enough but with weaknesses in some body parts. Some of us a combination of all. No one has perfect genes.
The list of genetic “curses” goes without end….
- Some individuals respond great to variations, some to training with high volume, some to high intensity, others to frequent training. It’s your job to find out what works the best for your body.
- Some individuals are able to gain muscle in no time without applying, while others fail to make any progress even though they are following some fantastic training program tailored for their needs.
If you find any difficulty in putting on muscle mass, and don’t respond well to certain training, try experimenting. With consistency and determination you’re bound to see results in the end.
