5 best diets for weight loss
1. Intermittent fasting
Intermittent fasting is a dietary strategy that involves periods of eating and fasting spread throughout the day or week. The most popular methods include the 16/8 method and the 5:2 method:
- 16/8 method: Involves fasting for 16 hours and restricting your eating window to 8 hours a day.
- 5:2 method: Allows you to have only 500-600 calories 2 days a week.
While intermittent fasting can help with weight loss, it’s important to avoid eating too much during the eating periods when you are allowed to eat.
If you are sensitive to fluctuations in your blood sugar levels (for example, if you have diabetes or an eating disorder), talk to your doctor before starting an intermittent fasting diet plan.
2. Mediterranean diet
For several consecutive years, the Mediterranean diet has won the top honor as the best diet in annual rankings.
This diet emphasizes eating plenty of fresh fruits, vegetables, nuts, whole grains, fish, olive oil, and a small amount of meat, dairy, and wine.
In addition to weight loss, health benefits include:
- Combats inflammation and oxidative stress
- Lowers blood pressure and cholesterol
- Regulates blood sugar levels
- May help with Alzheimer's disease
3. DASH diet
The DASH diet was developed specifically to help people with hypertension.
Food options available on the DASH diet focus on whole foods such as fruits and veggies, fat-free or low-fat dairy, whole grains, and lean meat, fish, and poultry. You need to cut back on processed foods such as sugary drinks and packaged snacks and limit red meat.
4. Low-carb diet
The Atkins diet and keto diet are examples of low-carb diets that restrict carb intake in favor of healthy fats and protein. This type of diet suggests that 30%-50% of your daily calories should be from proteins.
Carbs are your body’s main source of fuel. When you are on a low-carb diet, however, your body burns fat for energy instead, a state called ketosis. Ketosis occurs when fats are broken down into ketones, which are byproducts of fat metabolism.
Starting a low-carb diet can cause side effects, especially in the initial stages. Side effects may include:
- Headache
- Giddiness
- Tiredness
- Constipation
Ketosis can also cause side effects such as:
Before starting a low-carb diet, consult your doctor. Diets like the Atkins diet may not be suitable for you if you are on medications such as water pills (diuretics) or insulin or have health issues such as chronic kidney disease.
5. Paleo diet
The paleo diet is based on the theory that we should be eating the same foods as our ancestors during the Paleolithic era. This diet is also called:
- Paleolithic diet
- Stone age diet
- Hunter-gatherer diet
- Caveman diet
The paleo diet plan includes meat, fish, fruits, vegetables, nuts, seeds, and oils such as olive oil or walnut oil.
Some studies suggest that the paleo diet has health benefits including:
- Weight loss
- Improvement in glucose tolerance
- Regulation of blood pressure
- Better appetite management
However, there are no long-term clinical trials providing evidence about the benefits and risks of the paleo diet. And it’s important to remember that there is no one “true” paleo diet because it varies depending on the region.
