How long does Kuro Shuga take to work? What happens from the first meal to week 8

Short answer: In week 1 of ZENSO Kuro Shuga, most people first notice fewer sweet cravings, and they feel less heavy and less sleepy after meals. In weeks 2–4 (1 jar), the scale starts to shift and the waistband feels looser. In month 2 (2 jars), your waist is trimmer, with rice still on your plate. In a study of the lead ingredient, CQR-300®, at 300 mg a day, waist size was down 9% at week 8 (placebo 2%). Everyone starts from a different place, so take it for at least 30 days before you judge.

The timeline at a glance

The week-8 figures come from the CQR-300® ingredient study (67 people, placebo-controlled; Nash et al., 2019), not a study of Kuro Shuga. Results vary from person to person. You'll get more from it with balanced meals and exercise.

Why do some people see changes sooner than others?

• Different starting points: everyone eats different amounts of rice, noodles and sweet drinks.
• Whether you take it every day: taking it before both lunch and dinner means both meals are covered every day.
• Timing: chew it 30 minutes before the meal, so it's there before the enzymes get to work. After the meal is one step too late.
• How much you move: eat lunch out and sit all afternoon, and the carbs never get used. More movement gives better results.

Why do we recommend 2 jars?

The CQR-300® ingredient study ran for 8 weeks. One jar is 30 days; two jars are 60 days, so you cover the same 8 weeks as the study with nothing to re-order at day 30. Your advisor checks in on days 1, 7, 30, 45 and 60.

If you just want to try it, 1 jar (30 days) is enough to tell whether it suits you.

No change after a week. Is that normal?

Everyone is different. Check three things first:

1. Do you take it before both lunch and dinner?
2. Do you chew it 30 minutes before the meal?
3. Are you still drinking a lot of sweet drinks?

If you still don't feel a genuine difference within 30 days, message your advisor for a full refund.

Frequently asked questions

Does Kuro Shuga work from the first meal?

It's in place before the meal, so that meal's rice, noodles and sweet drinks have their checkpoint from that point. Changes in cravings usually come in week 1; weight and waistline are something to judge week by week.

How many kilos will I lose?

We don't give kilo numbers, because everyone starts from a different place. What we can share is the ingredient study: CQR-300® at 300 mg a day for 8 weeks, waist -9% and body weight -8% (placebo -2% and -0.6%). That is a study of the ingredient, not of Kuro Shuga.

Do I still need to watch my diet and exercise?

You don't have to give up rice, but balanced meals and more movement give better results.

Do I have to buy 2 jars?

No. To try it, 1 jar is enough to judge. To cover the full 8 weeks, like the CQR-300® study, choose 2 jars.
