“I am eating less than before, but nothing is changing.” If you have felt this, you are not alone, and you are not weak. The body has strong systems that guard against weight loss.

The body fights back

When you lose weight, your body thinks it is being starved. Hormones like leptin (which tells you that you are full) drop, and ghrelin (which makes you hungry) rises. At the same time, the body burns slightly fewer calories than before. This is why the last few kilos are the hardest.

Why crash diets backfire

Starving yourself loses muscle and water as well as fat, slows metabolism, and ends in strong cravings. Most people regain the weight, often more. Long-term studies show that regain is common, which is why we plan for keeping weight off, not only losing it.

What works better

  • A small calorie gap that you can live with, rather than extreme cuts.
  • Protein at each meal to keep you full and protect muscle.
  • Fibre from vegetables, dal and whole grains.
  • Regular walking and strength training to keep the muscle that burns energy.
  • Good sleep: short sleep raises hunger hormones.
  • Managing stress, which triggers emotional eating.

Medical reasons to check

Thyroid problems, PCOS, high insulin, some medicines (like steroids, some antidepressants and some diabetes medicines), and sleep apnoea can make weight loss harder. If you have tried hard without results, ask your doctor for a check.

Aim for progress, not perfection

Losing 5 to 10 percent of your weight already brings real health benefits: better sugar, BP and sleep. Celebrate smaller wins, like walking 5,000 more steps or a smaller waist.
