The Atkins diet will have you saying bye-bye to bread, and we’re not just talking about carbs. Finder.com analyzed seven popular diets to find that Atkins is the most expensive way to lose weight, requiring an estimated annual cost of $4,319.66 for an adult.
A normal diet recommended by the USDA costs the average adult $3,685.50 annually, putting the annual cost of Atkins at 17% more than your standard diet. Must be all those bacon strips and bacon strips and bacon strips.
The popular low-glycemic South Beach Diet comes in at second most costly. At an average cost of $4,074.54 a year, it’s 11% higher than the USDA’s recommended diet.
Trailing well behind both Atkins and South Beach, a vegan diet takes third place as most expensive. But it’s some 15% cheaper than the USDA recommended diet, with its diet of plant-based meals costing roughly $3,144.27 a year.
Of the diets we analyzed, a ketogenic — or keto — diet is the cheapest. At $2,444.22 a year, it’s roughly 43% less than what the Atkins diet will cost you and 34% less than the USDA recommended diet. Switching from the USDA diet to the keto diet could mean depositing an extra $1,241.28 into your savings this year.
To compute annual costs for each diet, we analyzed ingredients from weekly recipes for each diet and translated them to result in expenses for a year. We accounted for the fact that select ingredients are likely to last more than a week.

We weren’t able to find a research study published for Whole 30; therefore, we excluded it from our analysis. Weight loss for Paleo was reported over a three-week study, while the Mediterranean diet was reported over a two-year study. Because weight loss for keto was provided in intervals, we used the lower end reported — or 8.8 pounds. We converted weight loss reported in kilograms to pounds for our analysis.
