When it comes to health, diet is only part of the picture. If your gut, bowel, and intestinal system are sluggish or overloaded, even the healthiest food won’t deliver its full benefit. That’s why Flush GBI was created — to reset your digestive system so your body can better absorb and use the nutrients you consume.
There are two types of nutrients:
Essential nutrients — ones the body can’t make in sufficient amounts, so they must come from diet.
Conditionally essential nutrients — normally produced in the body, but not always in adequate amounts during illness or stress.
These nutrients fall into two main groups:
Macronutrients — carbohydrates, proteins, fats (and fibre).
Micronutrients — vitamins and minerals.
Food is fuel. The body’s main requirement is energy, measured in kilojoules (kJ) or, more commonly, kilocalories (kcal).
Two key measures determine your needs:
BMR/RMR (Basal/Resting Metabolic Rate): energy used at rest.
TDEE (Total Daily Energy Expenditure): your daily energy requirement based on activity.
The balance between intake and expenditure dictates whether you lose, gain, or maintain weight.
Flush GBI tip: When your gut is cleared and balanced, calorie intake is more accurately reflected in your energy levels — instead of being disrupted by bloating or poor digestion.
Often misunderstood, fat is vital for growth, cell function, and absorption of vitamins A, D, E, and K. The key is balance: avoid trans fats, keep saturated fats moderate, and focus on unsaturated fats (olive oil, avocados, oily fish, nuts, flaxseed).
The body’s primary energy source. Simple carbs (sugars) digest quickly and spike blood glucose. Complex carbs (whole grains, potatoes, oats, quinoa) digest more slowly, providing steady energy.
A carbohydrate the body cannot digest — but gut bacteria can. Fibre supports healthy digestion, satiety, and bowel regularity. High-fibre foods include whole grains, pulses, fruits, and vegetables.
Flush GBI advantage: By cleansing the bowel, fibre’s full benefits are restored — reducing constipation, balancing gut bacteria, and improving regularity.
Essential for immune function, transport, and DNA repair. Made up of amino acids (AAs), nine of which are essential.
Complete proteins: contain all nine (e.g., meat, eggs, soy, quinoa).
Incomplete proteins: low in one or more (e.g., wheat, beans, rice) but can be paired (rice + beans).
Vitamins and minerals support everything from vision and bone health to immunity and metabolism. Requirements are small but vital. Examples include:
Vitamin C (80 mg): antioxidant, wound healing.
Vitamin D (5 µg): bone and reproductive health.
Iron (14 mg): oxygen transport.
Magnesium (375 mg): nerve and muscle function.
Ensuring adequate intake means eating a variety of foods — especially fruit, vegetables, nuts, seeds, and whole grains.
Flush GBI reminder: Even if your diet is packed with micronutrients, poor gut health can block their absorption. Resetting the digestive system is key.
Maintain weight: eat at TDEE.
Gain weight: TDEE + 500 kcal daily.
Lose weight: TDEE – 500 kcal daily (approx. 1 lb/week).
However, weight management is not only about calories. Food quality matters. Diets low in nutrients but within calorie targets can still harm long-term health.
Flush GBI works alongside weight goals by clearing the gut, reducing sluggishness, and allowing nutrients to work more efficiently.
Calories drive energy balance, but nutrient quality drives health.
Macronutrients (carbs, fat, protein, fibre) and micronutrients (vitamins and minerals) are all vital.
A varied, balanced diet is the best way to meet nutritional needs.
Gut health underpins nutrient absorption — and this is where Flush GBI plays a critical role.
Optimal health = good food + proper absorption + lifestyle balance (sleep, hydration, movement, stress control).
