How to Lose Weight Fast: 3 Simple Steps, Based on Science

There are many ways to lose a lot of weight fast.

However, most of them will make you hungry and unsatisfied.

If you don't have iron willpower, then hunger will cause you to give up on these plans quickly.

The plan outlined here will:

1. Reduce your appetite significantly.
2. Make you lose weight quickly, without hunger.
3. Improve your metabolic health at the same time.

Here is a simple 3-step plan to lose weight fast.

1. Cut Back on Sugars and Starches

The most important part is to cut back on sugars and starches (carbs).

When you do that, your hunger levels go down and you end up eating much fewer calories

Now instead of burning carbs for energy, your body starts feeding off of stored fat.

Another benefit of cutting carbs is that it lowers insulin levels, causing your kidneys to shed excess sodium and water out of your body. This reduces bloat and unnecessary water weight 

It is not uncommon to lose up to 10 pounds (sometimes more) in the first week of eating this way, both body fat and water weight.

2. Eat Protein, Fat and Vegetables

Each one of your meals should include a protein source, a fat source and low-carb vegetables.
Constructing your meals in this way will automatically bring your carb intake into the recommended range of 20–50 grams per day.

Protein Sources

• Meat: Beef, chicken, pork, lamb, etc.
• Fish and Seafood: Salmon, trout, shrimp, etc.
• Eggs: Whole eggs with the yolk are best.

The importance of eating plenty of protein cannot be overstated.
This has been shown to boost metabolism by 80 to 100 calories per day
High-protein diets can also reduce cravings and obsessive thoughts about food by 60%, reduce the desire for late-night snacking by half, and make you so full that you automatically eat 441 fewer calories per day — just by adding protein to your diet
When it comes to losing weight, protein is the king of nutrients. Period.

Low-Carb Vegetables

• Broccoli
• Cauliflower
• Spinach
• Tomatoes
• Kale
• Brussels sprouts
• Cabbage
• Swiss chard
• Lettuce
• Cucumber
• Full list here.

Don’t be afraid to load your plate with these low-carb vegetables. You can eat massive amounts of them without going over 20–50 net carbs per day.
A diet based mostly on meat and vegetables contains all the fiber, vitamins and minerals you need to be healthy.

Fat Sources

• Olive oil
• Coconut oil
• Avocado oil
• Butter

3. Lift Weights 3 Times Per Week

You don't need to exercise to lose weight on this plan, but it is recommended.

The best option is to go to the gym 3–4 times a week. Do a warm-up and lift some weights.

If you're new to the gym, ask a trainer for some advice.

By lifting weights, you will burn lots of calories and prevent your metabolism from slowing down, which is a common side effect of losing weight 

Studies on low-carb diets show that you can even gain a bit of muscle while losing significant amounts of body fat

If lifting weights is not an option for you, then doing some cardio workouts like walking, jogging, running, cycling or swimming will suffice.
