What is keto and how does net carb tracking work?
Keto is a low-carb eating approach that shifts the body toward using fat for fuel. Keeping carbs low enough triggers ketosis. In ketosis, fat becomes the main energy source.
The idea is simple. But it does take attention to what you eat. Net carb tracking is the foundation.
What are net carbs?
Net carbs are the carbs your body digests and absorbs. The count removes fiber and most sugar alcohols from the total. These don't raise blood sugar much for most people.
The formula:
- Net carbs = Total carbs - Fiber - Sugar alcohols
On a strict keto plan, most people aim for 20-50 grams of net carbs per day. Everyone's limit is different. It depends on how active you are, your body, and your goals. Your provider or dietitian can help you set the right target.
What are the two main keto tiers at Nashua Nutrition?
Strict keto
Made for people in the early or active loss phase. Products here have 3 grams of net carbs or fewer per serving. The lower ceiling makes it easier to stay in ketosis.
Standard keto
Made for people in active loss or a more open phase. Products here have up to 6 grams of net carbs per serving. Good for people with more room in their daily carb budget.
How is keto different from IPA?
Both are low-carb. But they differ on fat.
Keto is high-fat. Healthy fats are a key fuel source. Ideal Protein Alternatives (IPA) is low-carb and low-fat. Products that work for keto may not fit IPA, and vice versa. If you follow IPA, visit the IPA page for products that fit that plan.
What about electrolytes?
In the first few days of keto, the body releases water. Electrolytes go with it - sodium, potassium, and magnesium. Some people feel tired, get headaches, or have muscle cramps in this period.
Keeping electrolyte intake up can help. Many people on keto use products made for this phase.

What macros matter most on keto?
A typical keto macro split looks like this:
- Fat: 60-75% of daily calories
- Protein: 20-30% of daily calories
- Carbs: 5-10% of daily calories
Exact ratios depend on your goals, activity level, and how your body responds. Your provider or dietitian can help you set the right targets.

Frequently Asked Questions
Keto Friendly Nutrition
Strict Keto limits you to 3g or fewer net carbs per serving — this is the level most people use during induction (the first 2–4 weeks) to enter ketosis quickly. Standard Keto allows up to 5–6g net carbs per serving, giving you more product variety while still supporting ketosis. Most people start strict and shift to standard once they're fat-adapted.
Net carbs = total carbohydrates minus fiber and certain sugar alcohols (like erythritol and allulose). This is the number that affects blood sugar and ketosis — not total carbs. Every product on this page displays net carbs per serving so you can track against your daily limit. Most keto programs target under 20g net carbs per day during induction.
Keto flu refers to headaches, fatigue, brain fog, and nausea some people experience during the first 1–2 weeks as your body switches from burning carbs to burning fat. It's primarily caused by electrolyte shifts — your body excretes more sodium, potassium, and magnesium in early ketosis. Supplementing electrolytes is the most effective way to reduce symptoms. Browse our Supplements & Electrolytes section for options.
Electrolytes are essential, especially during the first few weeks — sodium, potassium, and magnesium all drop when you cut carbs. Beyond that, many keto dieters benefit from MCT oil (which supports ketone production), fiber supplements (since grain-based fiber sources are eliminated), and a sugar-free multivitamin to cover gaps from restricted food groups. Browse our Supplements & Electrolytes section for keto-compatible options.
ost programs introduce soft-texture protein bars toward the end of Stage 4 (soft foods), typically around weeks 6–8. Bars with a softer, chewier texture are usually tolerated first. Crunchy or dense bars are better suited for Stage 5 and beyond. Start slow, chew thoroughly, and check with your bariatric team before adding them.
Not necessarily. Keto products are high-fat, which conflicts with Ideal Protein's low-fat requirement. Bariatric products have strict texture and portion requirements that keto products don't account for. Some products do overlap across protocols, but always check the specific protocol page to confirm compatibility. We label every product by protocol.
