Role of Genetics and Heredity Obesity


I have some friends who tell me that their obesity is simply due to their genetics. Is this true?

Because each person is born with a unique genetic composition, losing bodyfat and keeping it off can be more challenging for some people than others.

Your genes can influence how quickly you feel full when eating, how physically active you are prone to be, and your metabolic rate, for example. As a result, some people may be genetically more vulnerable to gaining weight and certain environmental triggers can make these people more susceptible to becoming obese.

So what percentage of the population is obese because of genetics? Some scientists claim that most obesity cases are influenced by genetics, some claim that the influence is negligible, and many believe that the right explanation rests between the two views.

Some scientists believe that certain inherited genes don’t necessarily make individuals obese, they merely give them a predisposition for becoming obese, but it is the learned or acquired behaviours of overeating and inactivity that cause the weight gain.

While science shows that heredity is linked to obesity, it is impossible to pinpoint the degree of correlation. There is little debate, however, over the genetic determination of body shape. Some people are more likely to put weight on their hips and thighs, and this is harder to lose than belly fat.

‘Obesity runs in my family, and it is impossible for me to lose weight’ is a classic excuse for not trying to lose weight, and it can be a convenient way of blaming others for an individual’s state.

Obesity tends to run in some families, suggesting a genetic link. But families also share diet and lifestyle habits that contribute to obesity. There seems to be a greater chance that people are heavy because of conditioned behaviours they learned from their family, than because of genetics.

People can still succeed with fat loss despite a genetic predisposition to gain weight, although it may take more work and patience, and perhaps medical intervention.

When You Are Sick, Is It A Good Idea To Workout?


Dedication is great, but training while you are sick does not help anybody. You should stay away from any training or other activity if you are not well. You are better off getting some rest and then coming back to the gym when you are healthy. Keep in mind that every time you go to the gym you need to give 100% to achieve your desired results. If your training intensity is compromised because you are sick you will not reach your goals. Unless your goal is to make other people sick, and you do not want to do that, you will be just wasting your time. Therefore, stay at home, get better, and come back ready to train hard.

Lift Away The Pain


Researchers at the University of Alberta studied the effects of weight training and cardio on backaches. Unless you have severely injured your back and the doctor has ordered bed rest, staying active, particularly lifting weights, will help you in recovery. Study participants who weight-trained three times per week decreased their pain by 63% compared to participants who did cardio only and reduced their pain by 6%. Resistance training targets both upper and lower body muscles, whereas cardio targets mainly lower-body muscles. You should continue with some cardio to avoid putting on unwanted bodyfat during recovery from injury, and do whatever strength training exercises you can handle with poundage that will not make your injury worse. You do not want to overdo it to find yourself sidelined and out of the gym indefinitely.

Powerful Cancer Protection


Exercise and caffeine both have anti-cancer properties. Scientists at Rutgers University conducted research on animals exposed to UVB radiation and found caffeine and exercise combined increased the animals’ ability to destroy skin-cancer cells by up to four times. Researchers suspect caffeine inhibits the genetic pathway ATR-1, preventing damaged cells from self-destructing. Caffeine and exercise both decrease tissue fat, helping cells deconstruct. Monique Ryan, author of Sports Nutrition for Endurance Athletes, recommends drinking a cup of strong coffee an hour before training. The caffeine will also help delay fatigue and increase endurance for a better workout.
