Eating well during GLP-1 treatment
How to organize food, protein, fiber, hydration and tolerance during GLP-1 treatment.
The essentials in less than a minute
- Eating much less does not always mean eating better; With less appetite the importance of choosing nutritious foods increases.
- Sufficient protein, plant foods, fiber, hydration, and tolerable portions help sustain the plan.
- Very large or fatty meals can worsen nausea in some people.
- The regimen should be adapted if there is diabetes, kidney disease, pregnancy, eating disorder or other clinical need.
The medicine does not design the diet
GLP-1-related treatments can reduce appetite and intake, but do not guarantee sufficient protein, vitamins, fiber, or hydration. When total volume decreases, each choice counts more.
AESAN’s NAOS strategy promotes a varied, balanced and moderate diet along with physical activity. During treatment, this principle is maintained, with adjustments according to tolerance and needs.
Build a useful plate
| Component | Examples | Objective |
|---|---|---|
| Vegetables and vegetables | Cooked or raw according to tolerance | Fiber, micronutrients and volume |
| Protein | Fish, eggs, legumes, dairy products, lean meats | Help preserve tissue and satiety |
| Quality hydrate | Potato, rice, oatmeal, whole wheat bread | Energy and adhesion |
| Fats | Olive oil, nuts | Nutritional quality in tolerable quantities |
It is not necessary to turn each dish into an exact formula. The employer must be able to maintain and respect culture, budget, schedules and preferences.
If there is nausea, reflux or fullness
Very fatty, large or fast meals may be worse tolerated. If there is repeated vomiting, inability to hydrate, severe pain or signs of dehydration, you should consult.
Preserve health, not just lower a number
Stall speed should not become a competition. An adequate plan looks at energy, strength, digestion, sleep, blood tests when appropriate, and relationship with food. Excessively rapid weight loss may be a signal to review intake and dosage.
Individual attention
People with kidney disease, treated diabetes, pregnancy, a history of eating disorders or special nutritional needs should receive adapted guidance.
