It is difficult to give a definite answer to this question, because the effect of orchid seeds as a meal replacement will vary from person to person and is also affected by many other factors, such as diet, exercise, living habits, etc.

Generally speaking, meal replacement products have lower calories than traditional diets. If you use orchid seeds to replace one meal and reduce the caloric intake of one meal a day, how much weight can you lose in a month?

Reducing 500 calories a day can reduce 15,000 calories a month.

Assume that the daily caloric requirement is 2,000 calories and the caloric requirement for a month is 60,000 calories.

So, how much weight can you lose in a month?

According to the formula: weight change (kg) = calorie change (calories) / 3500, the possible weight loss in one month can be calculated as:

15000 / 3500 = 4.285714285714286 kg

So, if you use orchid seeds to replace one meal, you may lose 4.285714285714286 kilograms in a month. However, please note that this is only a rough estimate and the specific weight loss effect will vary from person to person. In addition, over-reliance on meal replacement products may lead to nutritional imbalances and affect physical health. It is recommended to lose weight reasonably based on diet and exercise.
