Herbalife Formula 1 shakes are classified as total diet replacement (TDR) meal replacements that meet strict EU and UK nutritional guidelines, meaning they’re specifically designed to replace full meals safely, day after day.

What Long Term Means

What Does “Long Term” Actually Mean?

For most people, long term means using Herbalife shakes as a daily meal replacement — typically replacing one or two meals per day — for months or years. This is exactly what the products are formulated for. Unlike crash diets or very low calorie diets (VLCDs) that are only recommended for short periods under medical supervision, Herbalife Formula 1 is designed for sustained, everyday use.

EU & UK Guidelines

EU & UK Meal Replacement Guidelines — What They Actually Say

Herbalife Formula 1 shakes comply with EU Regulation No 609/2013 and the associated delegated regulations covering food for specific groups, including meal replacements for weight control.

Formula 1 meets all of these requirements. Each serving (two scoops with semi-skimmed milk) delivers a nutritionally complete meal in a glass — not a protein shake or a snack. See our full nutrition science breakdown for more detail.

Daily Safety

Is It Safe to Replace a Meal Every Day Long Term?

Yes. Because Formula 1 is a nutritionally complete meal replacement — not a supplement or a partial food — replacing one or two meals per day long term is safe for healthy adults. You’re not cutting out nutrition; you’re replacing it with a controlled, balanced alternative. Many of our customers have been using Formula 1 as their daily breakfast for years. See how Formula 1 is designed to support everyday nutrition.

⚠️

Medical note: If you have a medical condition, are pregnant, or are breastfeeding, always check with your GP first — this applies to any significant dietary change, not just Herbalife.

Nutritional Variety

What About Nutritional Variety?

One concern people raise is whether using the same shake every day leads to nutritional gaps. With Formula 1, this isn’t an issue — the vitamin and mineral profile is built into every serving. However, we always recommend that your remaining meals are balanced and varied.

🗓️ What a balanced long-term day looks like:

🌅

Breakfast

Formula 1 shake + PDM

🥗

Lunch

Balanced meal or Formula 1

🍽️

Dinner

Varied, nutritious meal

🍎

Snacks

Protein bar or fruit

💡 Pro tip:
Add Protein Drink Mix (PDM) to your shake to boost protein intake — especially useful if you’re active or trying to preserve muscle while losing weight. Read our guide on why protein helps fat loss.
