If you're new to structured eating for weight management, the options can feel like a lot. You don't need to have it all figured out before you begin.
This page explains the most common approaches so you can find what fits your situation.
What are the most common structured nutrition approaches?
Most people at Nashua Nutrition follow one of four plans - or a mix of them.
GLP-1 supportive nutrition
For people using GLP-1 medications like semaglutide or tirzepatide. The focus is on high-protein, easy-to-eat products. The goal is to meet your protein needs even when appetite is very low.

Bariatric nutrition
For people who have had or are preparing for bariatric surgery. The focus is on texture-safe, protein-forward foods that fit each stage of recovery. Your bariatric team leads the plan.

Ideal Protein Alternatives (IPA)
For people following a high-protein, low-carb, low-fat plan similar to the Ideal Protein protocol. Products are classed as unrestricted (up to 2 per day) or restricted (up to 1 per day). The split is based on carb and calorie levels.
Keto
For people following a low-carb, high-fat eating plan. The focus is on net carb tracking. Products are sorted into strict and standard tiers.
What if I'm not following a specific plan?
Many people use high-protein meal products without following a named protocol. Your goal might be more protein, fewer calories, or easy prepared foods. Our best sellers are a great place to start.
You can also browse by food type - shakes, soups, bars, breakfast, and more - to find what fits your routine.
What should I look for in a product?
A few things are worth checking no matter which approach you follow:
- Protein per serving: higher is generally better when calories are limited
- Net carbs: matters if you follow a low-carb or keto plan
- Texture: key if you're post-op bariatric or on GLP-1
- Ingredients: check for allergens and protein sources that fit your plan
Every product page has full nutrition info to help you compare before you buy.
Where do I go if I'm still not sure?
The best source of guidance is your healthcare provider, dietitian, or bariatric team. They can match your nutrition needs to your health history, goals, and medications.
If you want help finding products on our site, our team is available by phone at 1-800-649-1374 or via the contact page.
Key takeaway
You don't have to know your exact protocol to get started. Understanding the basics - protein, carbs, texture, and structure - is enough to begin. We've sorted our products to make that as simple as possible.

Frequently Asked Questions
Ideal Protein Alternatives
It depends on your situation. If you're on GLP-1 medication like Ozempic or Wegovy, start with our GLP-1 page. If you've had or are preparing for bariatric surgery, our Bariatric page organizes products by surgical stage. If you're following the Ideal Protein protocol through a clinic, check our IPA page. If you're committed to a ketogenic diet, our Keto page has you covered. If none of those apply - or you're just looking for high-protein, low-carb options without a specific program - you're in the right place.
Protein helps preserve muscle mass while you lose fat, keeps you feeling full longer, and requires more energy to digest than carbs or fat. Most weight loss programs recommend 60-80 grams of protein per day as a starting point - some go higher depending on your body weight and activity level. Protein shakes, bars, and high-protein meals make it easier to hit that target without excessive calories.
Yes - when used as part of a structured approach. Research across multiple programs shows that meal replacements help with portion control, calorie consistency, and convenience. They work best when they replace 1-3 meals per day during active weight loss, then taper down as you transition to more whole foods. They're not meant to replace real food forever - they're tools to simplify the hardest part of getting started.
Keto is a specific protocol that requires very low carb intake (under 20g net carbs per day) to put your body into ketosis - a state where you burn fat for fuel. It also requires high fat intake. Low-carb is a broader, more flexible approach - generally under 100g net carbs per day - that doesn't require ketosis or high fat. If you want structure and strict macros, keto might be your fit. If you want a simpler approach without tracking ketones, low-carb is a good starting point.
Most weight loss programs recommend 5-6 smaller eating occasions per day - roughly every 2-3 hours. This keeps blood sugar stable, reduces cravings, and prevents the extreme hunger that leads to overeating. A typical structure might be 3 meal replacements or high-protein meals plus 2 snacks, with a self-prepared dinner built around lean protein and vegetables.
We're not a diet program - we're a product store that supports whatever plan you're on. The difference is having convenient, pre-portioned, high-protein foods ready when willpower runs low. Most diets fail because they require too much daily effort around meal planning and prep. Having the right products on hand removes that friction. Start small, find a few products you like, and build from there.
