The excuse
“Eating well is too expensive”
Using cost as the reason not to eat in a way that supports getting lean.
Eating well does cost more per calorie, but the total cost of eating poorly is far higher.
What the evidence shows
- 1
Real but small price gap
Healthier diet patterns cost about $1.48 more per day on average, which is a real barrier for the lowest-income households, but a manageable one for most people who cite cost as a reason to avoid eating well.
- 2
Cheap strategies exist
Tactics like delaying breakfast to improve blood sugar control, prioritizing staple proteins over premium cuts, and using subsidized produce programs carry little to no extra cost and still meaningfully improve body composition outcomes.
- 3
Poor eating is medically expensive
A digital nutrition intervention cut direct medical costs by nearly 520 euros per person and reduced type 2 diabetes prevalence by 1.6 percentage points, meaning the downstream healthcare bill from eating poorly routinely dwarfs any grocery savings.

Income shapes access, not just choice
At the lowest income level, the share of people eating the highest quality carbohydrates fell from 26.9% to 20.6% over time, confirming that food insecurity is a structural problem, but food pricing interventions like taxes on junk and subsidies on produce have shown the strongest dietary improvements in exactly these lower-income groups.
The cost complaint is not entirely wrong. Healthier meats, proteins, and calorie-dense whole foods do cost more per serving, and for households spending close to half their income on food, that gap is genuinely constraining. The excuse collapses, though, when you account for what poor eating ultimately costs in medical bills, lost productivity, and quality of life.
Start with the free and cheap levers first, such as meal timing, cutting ultra-processed snacks, and shifting toward beans and eggs, then redirect the money you stop spending on junk toward higher-quality whole foods.

Evidence that answers it56
Both groups experienced a decrease in per member per month (PMPM) expenses, with a 38% decrease in the experimental group.
Energy balance · ev 5/5Delaying breakfast to 0930 or 1200 h is a low-cost strategy to improve glycaemic management in people with type 2 diabetes.
Metabolic adaptation · ev 5/5There are two primary types of interventions tested for obesity among individuals with food insecurity: behavioral weight loss counseling and subsidies for food.
Energy balance · ev 5/5Cost sharing was associated with significantly greater initial engagement compared to total subsidy (OR 3.73, P < 0.001).
Energy balance · ev 5/5Mass media + total subsidy group had significantly greater calls and weight loss at 12 months compared to mixed campaign + total subsidy (-2.6% vs -1.8%, P = 0.04).
Energy balance · ev 5/5Cost sharing does not contribute to better participation or weight loss relative to total subsidy.

Where the concern is fair51
Healthier food-based diet patterns cost significantly more than less healthy options, with an average increase of $1.48 per day and $1.54 per 2000 kcal.
Mixed · ev 5/5Healthier meats and protein options cost significantly more per serving and per calorie than less healthy options.
Mixed · ev 5/5Healthier nutrient-based diet patterns do not cost significantly more per day than less healthy options, but cost more per 2000 kcal.
Mixed · ev 5/5Perceived cost remains a barrier to adherence to the gluten-free diet.
Energy balance · ev 5/5Food insecurity is associated with reduced dietary quality and excess weight gain.
Energy balance · ev 5/5At the lowest income level, the proportions of individuals in the best carbohydrate quality category reduced from 26.9% to 20.6%.
