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.

Glutamine Basics


What Is It?
A free-form amino acid that is abundant in the body, especially in skeletal muscle, and in most protein-rich foods. The body’s glutamine level is depleted with exercise and dietary stress.

What Does It Do?
When ingested as a free-form amino acid, glutamine supports the immune system stops muscle wasting and increases protein synthesis. It also acts a potent inhibitor of myostatin hyperactivity.

When Should It Be Taken?
30 minutes to 1 hour before and immediately after weight training.

How Much?
Take 5-10 grams per dose, starting with the lowest dose and working your way up according to individual tolerance.

Increasing Weight Lifted and Stuggling With Chest Growth?


My chest growth has stalled. I’m puzzled because I always add weight from workout to workout. Isn’t consistently adding weight the key to new size?

Gains in size usually accompany gains in strength, but not always. You have to consider the amount of stress placed on the muscle. Powerlifters are incredibly strong, but they do not have the muscle size of a bodybuilder. This is because a powerlifter’s goal is to move weight from point A to B, while a bodybuilder’s goal should be to place a significant amount of stress on the muscle to make it grow in size. Perhaps the problem is not how much weight your lift, but how you lift it. Are you really connecting your mind to the muscle and feeling it through a range of motion? The difficulty could also be a matter of volume or stagnation in your current exercise selection. Sometime changing the tempo of the reps, the angle of the exercises, or the overall volume of the workout can aid growth better than simply moving more weight.

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.

Ice Cold For Blasting Fat


Drinking Ice Cold Water

British researchers found that drinking refrigerated water increased exercisers’ energy levels, especially in hot-weather workouts. Athletes who drank chilled water during exercise worked out 25% longer than people drinking the same amount of room-temperature water. Those participants also claimed their workouts felt easier. Fill your water bottles with cold water right before training in the gym ready for sipping before and during your training session. It will help keep your core body temperature down and your energy up so that you can perform your best and maximise your calorie burn.
