Indulge meal (or cheat meal) usually means that at a special moment in the diet plan, you can relax your diet restrictions and enjoy some foods that you don't usually eat. Whether to enjoy an indulgent meal before or after meals is a matter of personal preference, and there are no fixed rules.

Some people like to enjoy an indulgent dinner before dinner, so they may feel more satisfied and eat less at dinner. This method can give you more control at dinner and avoid overeating.

Others like to enjoy an indulgent dinner after dinner, so that they can better control their dinner intake. Indulgence after dinner will provide them with a reward and satisfaction.

Most importantly, you should be moderate when enjoying a big meal. Try to choose high-quality food and pay attention to controlling the overall intake. If you have a specific diet plan or a special health condition, please consult a professional for more specific advice.
