How to train and eat healthily without overloading your budget. The cheapest protein sources, purchasing strategies, use of seasonal products.

One of the biggest myths is that sports nutrition is expensive. The truth is that a balanced athlete's diet can cost the same or even less than a regular diet if you know what and where to buy. Chicken, eggs, oats, rice, seasonal vegetables — these are products that are both cheap and nutritious.
Sports supplements often make up the largest share of expenses, but they are not necessary. A properly composed diet from regular food products can fully meet all an athlete's needs. Supplements are a convenience, not a necessity.

Large packages (5 kg of rice, 2 kg of oats) cost 30–50% less than small ones. Buy chicken in 2–3 kg quantities and freeze in portions. An investment in a freezer pays off within 2–3 months.
Seasonal vegetables and fruits cost 40–60% less. In summer — tomatoes, cucumbers, zucchini. In winter — cabbage, carrots, beetroot, frozen vegetables. Frozen vegetables are just as nutritious.
Saturday market — 20–30% cheaper than supermarkets. Online sports supplement stores with promotions. Wholesale outlets (Promo, Selver, Maxima large quantities) for meat and grains.
Homemade food costs 3–5 times less than in restaurants or when ordering. You can make a protein bar for 0.50€ (2–3€ in a store). A protein shake at home — 0.80€ (3–4€ in a store).
