A patient reported that the more strictly they dieted, the stronger their cravings became.

This is not a failure of discipline. It is a biological response.

When calorie intake drops and weight begins to decrease, the body activates compensatory mechanisms to restore energy balance.

Ghrelin, the hunger hormone, increases. This amplifies appetite and makes food more rewarding.

At the same time, leptin levels fall. Since leptin signals fullness and energy sufficiency, its reduction removes the “stop eating” signal.

The combined effect:
– Stronger cravings
– Increased hunger frequency
– Reduced satiety after meals

In parallel, the brain becomes more responsive to high-calorie foods, increasing the likelihood of overeating.

This is why stricter dieting often leads to stronger cravings, not less.

The body is not trying to help you lose weight.
It is trying to restore what was lost.

Effective fat loss strategies account for these hormonal shifts instead of ignoring them.

A patient reported intense, uncontrollable hunger soon after losing weight.

This is not a discipline issue. It is a predictable biological response.

When the body detects weight loss, it does not interpret it as success. It interprets it as a threat to survival and activates mechanisms to restore the lost weight.

The first change is a rise in ghrelin, the hunger hormone. This increases appetite, often making you feel hungry even after eating.

At the same time, leptin levels drop. Leptin signals the brain that energy stores are sufficient. When leptin decreases, the brain continues to drive hunger and food-seeking behavior.

The combined effect:
– Increased hunger
– Reduced satiety
– Stronger cravings

In parallel, the body reduces energy expenditure. Metabolism slows down to conserve energy, making fat loss harder and regain easier.

This is why many people regain weight after dieting.

It is not failure. It is physiology.

Long-term fat loss requires working with these hormonal responses, not against them.

A patient came in after losing 4 kg in 10 days and assumed the fat was gone.

What actually dropped that fast was not pure fat.

Rapid weight loss is largely driven by depletion of glycogen and water. Along with this, aggressive calorie restriction often leads to muscle breakdown.

Muscle loss is not a minor side effect. It directly lowers metabolic rate, reducing the body’s ability to burn calories at rest.

This creates a misleading phase:
the scale goes down quickly, but fat loss is limited, and metabolic capacity declines.

When normal eating resumes, the slower metabolism increases the likelihood of rapid weight regain.

Sustainable fat loss follows a different pattern:
– Slower rate of weight reduction
– Preservation of muscle mass
– Stable metabolic function

The goal is not fast weight loss.
The goal is maintaining fat loss without damaging the system that sustains it.

BariatricsByRajat is the brainchild of Dr. Rajat Gusani.

An alumnus of Pramukhswami Medical College, Karamsad, he has always had a keen interest in obesity surgery. Following his stint in Karamsad, as an Assistant Professor, he did his fellowship in bariatric surgery from Asia’s highest volume center. Throughout his stint of one year, he gained in-depth knowledge in the field of obesity surgery. Being academically inclined, he has several publications to his name:
