Can You Keep Weight Off Forever? Experts Say It Takes More Than Dieting

Can You Really Keep Weight Off for Life? Experts Say Lasting Success Starts With Sustainable Habits

Losing weight may be difficult, but keeping it off is often an even bigger challenge. While crash diets and viral weight-loss hacks promise quick results, health experts say lasting success has little to do with temporary restrictions and everything to do with building habits that support long-term metabolic health.

According to Dr Himika Chawla, Senior Consultant, PSRI Hospital (MD, General Medicine; DM, Endocrinology), one of the biggest misconceptions is viewing weight loss as a short-term goal.

“Weight management is not a 30-day challenge; it is a lifelong health strategy,” she says.

Why Weight Often Comes Back

Many people regain weight after initially shedding kilos, but experts stress that this isn’t simply due to a lack of willpower.

Dr Chawla explains that after weight loss, the body activates natural defence mechanisms by increasing hunger hormones while slowing metabolism, making it harder to maintain the new weight. This biological response is one reason why long-term weight maintenance is often more challenging than losing weight itself.

She warns against crash diets, saying they may deliver rapid results but are rarely sustainable. They can also trigger muscle loss, nutritional deficiencies and intense food cravings, increasing the risk of regaining weight.

Sustainable Eating Wins Over Restrictive Diets

Sneha, Clinical Dietitian at Maccure Hospital, believes overly restrictive diets often do more harm than good.

“Most people do not fail diets; diets fail people,” she says.

Instead of chasing perfection, she recommends an eating pattern that includes adequate protein, fibre, essential vitamins and minerals while maintaining a healthy calorie deficit. The goal, she adds, is to create a routine that remains practical during busy schedules, celebrations and stressful periods.

• Weight Loss Is More Than Diet Alone
• Experts agree that food is only one part of the equation.

Dr Chawla says regular physical activity, quality sleep, stress management and periodic medical follow-ups all play vital roles in maintaining a healthy weight. She also highlights that obesity is a chronic metabolic condition linked to diabetes, hypertension, fatty liver disease, heart disease, polycystic ovary syndrome (PCOS), infertility and joint problems.

Even losing just 5-10% of body weight, she notes, can significantly improve blood sugar, cholesterol, blood pressure and overall energy levels.

Everyday Habits Matter

Sneha points out that daily eating patterns often have a bigger impact than occasional indulgences.

She says many Indian meals tend to be heavy in refined carbohydrates while lacking sufficient protein and fibre. Frequent consumption of fried snacks and sugary drinks can also contribute to gradual weight gain.

Protein- and fibre-rich foods, she explains, help increase satiety, reduce unnecessary snacking and make it easier to stick to healthy habits without feeling constantly hungry.

• Medical Conditions Can Affect Weight
• Weight gain isn’t always caused by lifestyle alone.

Dr Chawla says conditions such as hypothyroidism, insulin resistance, menopause and PCOS, along with certain medications, can make weight loss more difficult. She advises people struggling to lose weight to undergo proper medical evaluation instead of relying solely on diet and exercise.

She adds that weight-loss medications can benefit carefully selected patients, but only under medical supervision and alongside healthy lifestyle changes.

• The Real Challenge Begins After Weight Loss
• Experts emphasise that reaching a target weight is only the beginning.

Sneha advises people not to return to old eating habits after achieving their goals. Instead, healthy eating patterns should evolve to support long-term weight maintenance.

Dr Chawla also recommends regular exercise, mindful eating, routine health check-ups and addressing small weight gains early before they become difficult to reverse.

Consistency Over Perfection

Both experts agree there is no one-size-fits-all solution to weight management.

The most effective plan is one that fits an individual’s age, medical history, lifestyle, food preferences, cultural habits, sleep, stress levels and budget. Rather than chasing quick fixes, focusing on sustainable habits and consistency offers the best chance of losing weight—and keeping it off for the long run.
