Want to lose weight by summer—comparing GLP-1 and fat-dissolving injections
The right choice for your goal and situation
"Do you want to lose weight generally, or are you only concerned about your stomach?"—This single question largely determines whether you should choose GLP-1 or fat-dissolving injections.
As demand for "getting in shape" for summer rapidly increases, our clinic offers both online prescriptions for GLP-1 drugs (Ozempic/Mounjaro) and in-person treatments for fat-dissolving injections (Cabelline). This article honestly compares the two and suggests the best choice for your goals.
- GLP-1 (Ozempic/Mounjaro) online prescription available nationwide
- Fat-dissolving injections (Cabelline) available for in-person treatment (Tokyo, Aoyama)
- If you're unsure which to choose, please consult us online

| Best for | Overall obesity, difficulty controlling appetite | Concerned about specific areas like abdomen, face, upper arms |
If "whole-body fat reduction" is your goal, GLP-1
If you have a generally high body weight or a high BMI, GLP-1 for systemic weight management is suitable. Since calorie intake naturally decreases due to appetite suppression, body fat is reduced not just in specific areas but throughout the entire body.
- Those with a BMI of 25 or higher who want to lose overall weight
- Those who struggle with appetite control and overeating
- Those who find clinic visits difficult or want to complete treatment online
- Those who want to manage their diet long-term
If "localized fat reduction" is your goal, fat-dissolving injections
If your body weight isn't particularly high but you're concerned about specific areas like your abdomen, jawline, upper arms, or thighs, fat-dissolving injections are suitable.
- Those with a standard weight but concerned about localized fat
- Those who want pinpoint results on the abdomen, under the chin, or upper arms
- Those who want to improve their silhouette for swimwear or lighter clothing
- Those seeking treatments with short downtime
Is combining them the best approach?
If you want to lose weight generally while also targeting specific areas, the most effective combination is to reduce overall weight with GLP-1 and add fat-dissolving injections to areas of concern. Our clinic can guide you through combination plans, offering GLP-1 prescriptions online and in-person fat-dissolving injections.
💡 "Will I make it by summer?" GLP-1 takes 1-3 months to show effects. With fat-dissolving injections, downtime subsides in 1-2 weeks, and changes are noticeable in 1-2 months. If you're aiming for the peak of summer (July-August), we recommend starting now.
Frequently Asked Questions
Yes. It is possible to combine GLP-1 for overall weight management with fat-dissolving injections for specific areas. Our clinic offers both, so please consult us about combination plans.
It varies depending on the area and amount of fat, but typically 2-4 sessions every 2-4 weeks. Some people feel a difference after one session, but multiple sessions are recommended for more reliable results.
On the day of the injection, please avoid strenuous exercise, bathing, and alcohol. Normal activities can be resumed the next day. Swelling and hardness may persist for several days but will subside over time.
