BURNBOX 3 Day Fasting Kit is a timed drink supplement kit for intermittent or water fasting, with 48 packs for four 3-day fasts and a printed fasting guide.
Fasting schedules can be difficult to organize when drinks and supplements are being used at different times of day. BURNBOX combines its drink sachets with a printed schedule, making it easier to follow a planned routine for intermittent or water fasting. The kit is designed to support weight management and appetite control; its fiber shakes may help promote fullness.
The box contains 48 packs arranged as four complete 3-day fasts, or 12 fasting days in total. Each fast uses 12 packs: the kit includes 24 grapefruit Anti-Hunger Fiber Shakes, 12 lime Electrolyte Boosters, and 12 chicken Bone Broth sachets.
The included accessories and instructions make this a coordinated set rather than sachets alone. The printed 3-Day Fasting Guide is made for women and men.
The guide sets out four drinks across the day: a Fiber Shake at 8–10 AM, an Electrolyte Booster at 2–4 PM, Bone Broth at 6–8 PM, and a second Fiber Shake at 9–10 PM. Each packet is assigned a time in the included guide, for use with an intermittent or water-fasting schedule.
This timed plan is intended to support appetite control and weight management while following the fasting routine. The schedule gives each of the kit’s drink types a place in the day.
Each grapefruit Fiber Shake has 25 calories, 4g psyllium husk, and 4g dietary fiber, including 2g soluble fiber. Two shakes provide about 95 calories per fasting day across the kit’s drink plan; the shakes may help promote fullness and curb cravings while keeping you within a fasting window.
Each lime Electrolyte Booster provides 960mg potassium, 640mg sodium, 600mg chloride, 380mg phosphorus, 300mg calcium, and 140mg magnesium. The savory chicken Bone Broth adds 5g broth and 4g protein. Per fasting day, the kit provides about 1,400mg sodium and 1,030mg potassium.
No. The Fiber Shake and Electrolyte Booster are plant-based, but the Bone Broth contains real chicken bone broth, so the complete kit is not vegan. The drinks are sweetened with stevia and have no added sugar.
Take each Fiber Shake with at least a full glass of water. Taking it without enough liquid may cause choking, so having sufficient water with the shake is an important part of using the kit.
BURNBOX 3 Day Fasting Kit is suited to adults who want a scheduled set of drinks and supplements for four 3-day fasting periods, with a guide and preparation accessories included. Because its Bone Broth contains chicken, the complete kit is not intended for vegan use.
