Medical Note

"Any pre-surgical dietary protocol should be reviewed with your surgical team and primary care physician. Rapid weight loss before surgery affects medication dosing, anaesthetic risk, and liver size — your surgical team needs to be informed and involved."

Why Pre-Surgical Weight Loss Matters

Surgeons require weight loss before bariatric and other procedures for clear clinical reasons:

Reduces liver size (hepatomegaly from fat infiltration). A smaller liver creates more surgical access and reduces operative risk significantly
Reduces overall surgical risk from obesity-related complications (DVT, wound healing, anaesthesia)
Demonstrates behavioural readiness for post-surgical dietary compliance
Some surgeons require 5–10% weight loss; others specify a maximum BMI for their technique

BMI above 40 is often an absolute contraindication; above 35 is frequently a conditional barrier
Reduced weight improves implant longevity and reduces complication rates

Reduced abdominal adiposity improves surgical access and wound healing

Why the Sprint Is Appropriate for Pre-Surgical Use

The Fat Loss Sprint is specifically suited to pre-surgical weight loss because:

1. Speed. Most surgical deadlines are 4–12 weeks. The sprint achieves 5–15 kg of fat loss in 14–28 days — faster than any gradual approach 2. Liver fat reduction. Lim et al. (2011) demonstrated liver fat normalisation within 7 days of beginning structured caloric restriction — directly relevant to bariatric pre-operative liver reduction requirements 3. Defined protocol. Surgical teams respond well to structured, documented dietary interventions. The FLS has a defined protocol with daily tracking 4. Safety profile. Built on 50+ years of PSMF clinical evidence. Endorsed by NICE, EASO, and AHA/ACC. Mandatory supplementation and 800 kcal floor

Liver Fat Reduction — The Key Pre-Bariatric Benefit

Lim et al. (2011): Liver fat normalised within 7 days of 600 kcal/day dietary restriction — independent of weight loss magnitude. This is the mechanism behind pre-bariatric liquid diet protocols. The FLS achieves the same hepatic response through its very low calorie design with the 800 kcal safety floor rather than a purely liquid replacement.

This is clinically significant: a smaller, less fatty liver is the primary goal of most pre-bariatric dietary interventions. The sprint achieves it within 1–2 weeks.

Your surgical team set the target. The sprint is the structured path to it.

Individual results vary based on body composition, adherence, sex, age, and other factors.

Lipoly is not suitable for: pregnancy, breastfeeding, type 1 diabetes, active eating disorders, severe kidney or liver disease, or body fat below 12% (male) / 18% (female). See full eligibility criteria and contraindications in the app.

If you are currently taking prescription medication — including GLP-1 agonists, insulin, sulfonylureas, SGLT-2 inhibitors, or any other weight-related or metabolic medication — do not stop, reduce, or substitute your medication without guidance from your prescribing doctor. Rapid metabolic changes during a structured dietary protocol may require medication dose adjustment and must be managed under medical supervision.
