Weight, Genetics and Health: Understanding What You Can Control

If you have spent years struggling with your weight, it is highly possible you have fallen into an exhausting cycle of self-blame. You may have rigidly counted calories, cut out entire food groups, or exercised intensely, only to find it is still a struggle or just to see the weight return the moment you stop. Many people mistakenly believe that weight gain is simply a personal failure, a direct result of eating too much or moving too little.

At Dr Bazire’s medical clinic, we view weight management through a compassionate, medically informed lens. Obesity is not a character flaw or a lack of willpower; it is a complex medical condition determined by the interaction between ourselves and our environment. Our genes establish the ways our body can respond, but there is an overriding mechanism that determines which of those ways is actually used. This is called epigenetics.

Genetics vs Epigenetics

Our genes are the unalterable blueprint we are born with, whereas epigenetics refers to the ability to switch those genes on or off. As most processes in the body are influenced by several genes, each one with a slightly different impact, it is the epigenetic balance that determines the final outcome, by switching different genes on or off. It is often said that the genes are the engine and epigenetics the steering wheel; while we cannot change our genes, through our decisions and actions we can alter our epigenetic profile, changing the way our bodies respond to a given situation or stimulus.

Appetite and Satiety Regulation:

Your genes partially determine how strongly your body senses and responds to hunger, fullness and satiety signals. For some people, this means they may feel hungry more often, feel less satisfied after eating, or find it harder to manage cravings, even when they are trying to make healthy choices.

Basal Metabolic Rate (BMR)

Your genes influence the number of calories your body burns at rest, which directly affects how much of the energy you eat will be stored as fat.

Nutrient Responsiveness:

Biological wiring controls how efficiently your body processes macronutrients, particularly carbohydrates, altering your susceptibility to insulin resistance.

The Defended Set-Point:

Your genetics influence how aggressively your body triggers survival mechanisms, such as slowing metabolism and increasing hunger signals, to rapidly regain weight after a diet.

Why Standard Dietary Advice Continually Fails

The conventional advice to "eat less and move more" is fundamentally flawed because it treats weight loss purely as a mathematical equation of calories in versus calories out. When genetics is a core driver of obesity, severe calorie restriction can backfire by triggering survival responses and boosting appetite, especially for high-energy foods. This can block weight loss and increase the risk of a loss of lean muscle mass rather than fat tissue, which will lower your metabolic rate and set the stage for rapid weight rebound.

Furthermore, biological hunger dysregulation means that unsupported dieting is a constant psychological and physiological battle. Understanding that the interaction between your environment and your biology is working against you is not a reason to give up; rather, it can be incredibly liberating. It proves that past failures were not a lack of discipline, but the lack of an appropriate medical intervention.

To overcome genetic barriers, we utilise advanced medical strategies to stabilise your internal biochemistry. When appropriate, this includes the use of medical nutrition programmes and GLP-1 receptor agonist medications (such as Mounjaro, Wegovy, or Saxenda), which replicate natural satiety hormones to correct underlying appetite dysregulation and thus level the physiological playing field.
