It can happen for a variety of reasons, and often you eat very little but don't lose weight. Hence the feeling of wasting time and effort (i.e., the difficult effort of reducing meals and food intake).
In reality, disappointment can arise from some mistakes:
- We eat little during regular meals (lunch and dinner) but during the day we nibble on drinks, snacks, tastings throughout the day or portions perceived as small can add more calories than you think.
- Stress, menstrual cycle, high salt intake, certain medications, or hormonal changes they can cause fluid retention and mask fat loss.
- If you eat very little for a prolonged period, the body can adapt by partially reducing energy expenditure: one moves less spontaneously, one may feel more tired and some metabolic functions become more efficient.
- Body weight may fluctuate by 1–3 kg or more within a few days For reasons unrelated to body fat, it's more useful to look at the average over several weeks to assess trends.
While eating less is still crucial to losing weight, two factors still play a role in achieving your goals: calories, which are more important than the amount of food you eat; and physical activity, which should always be combined with your diet.
