Low-Carb & Micronutrient Trackers
Wise Eating vs Carb Manager: Complete Vitamin & Electrolyte Balance vs Keto-Only Tracking
TL;DR — Direct Answer
Carb Manager is purpose-built for ketogenic and net-carb counting, gating full micronutrient panels, meal planners, and fasting tools behind its Premium tier. Wise Eating tracks carbohydrates, dietary fibre, and sugars alongside all 22 vitamins and 11 minerals (including potassium, magnesium, calcium, and folate) for free across 12,601 offline USDA foods on iPhone and iPad.
Carbohydrates, Electrolytes & Micronutrient Visibility
Cutting carbohydrates alters fluid balance and cuts out fortified grains and fruit, making magnesium, potassium, folate, and fibre critical to watch.

The hidden micronutrient risk of strict carbohydrate restriction
Eliminating legumes, whole grains, starchy tubers, and higher-sugar fruits removes several of the easiest dietary sources of magnesium, potassium, folate, thiamin, and soluble fibre. Watching only net carbs tells you why ketosis continues, not why your calves cramp or your digestion slows down.
Because Wise Eating surfaces all 39 USDA nutrient fields on the free tier, you can verify daily magnesium, potassium, and fibre right alongside carbohydrates and sugars.
Scratch cooking without separate recipe and grocery apps
Anyone eating low-carb cooks more meals at home. Wise Eating prices your personal recipes into exact USDA nutrient totals, tracks meat and produce expiry dates in your fridge and freezer, and builds grocery lists from what you actually ran out of.
