The Happy Tum Plan: Lose 10 lb in 21 days


Feeling bloated and lacklustre? Waist size increasing for no reason? The latest research says it’s all about your gut…

Lose 10lb in 21 days

The G Plan diet, created by nutritionist Amanda Hamilton, helps you eat meals that boost your gut health and lose weight. The promise is that it’s not a diet of restriction but one of abundance and diversity. It has particular benefits if you feel bloated, are low in energy, or experience indigestion and heartburn.


The science bit

Your gut contains trillions of microbes, which help you digest food. They also provide enzymes and vitamins, and control the calories you absorb. Most of the bacteria in your body is found in your gut. Bacteria is known as your microbiota and collectively they form your microbiome. Everyone’s microbiome is unique – if it’s out of balance, your overall health is affected. Gut microbes affect your metabolism, altering the way you store your fat, so the wrong mix of microbes doesn’t bode well for your waistline. By introducing foods that are friendly to your microbiome, you’re likely to lose weight, have more energy and clearer skin.

Did you know?
The bacteria that live in the lower part of your gut weigh 3lb.

The Rules

The G Plan diet is divided into three phases.

» Try to stick to three meals a day.
»Vegetables should make up at least half of your plate at every meal.
» Your protein intake should be palm-sized.
» If you do need a snack, don’t have more than two a day. The aim is to eliminate grazing. If you’re hungry between meals, try drinking a glass of water or a herbal tea.
» If weight loss is your main goal, take a photo of yourself before you start, note your weight and waist, hip, arm and thigh measurements.

Phase 1:


Rest (5 days)

Start each day with a mug of hot water, a slice of lemon and a few thin slices of ginger, followed by a smoothie. Lunch and dinner are lightly cooked, not raw.

Off The Menu: Processed foods, added sugar, alcohol, gluten, dairy, carbonated drinks and certain vegetables (potatoes, tomatoes, aubergines, peppers).

Limited Foods: Grains, caffeine (two cups of green tea a day max), beans and pulses.

The Aim: To temporarily swap common gut irritants for gut-soothing foods.

The Bonus: Your weight loss will get a kick-start – and no more bloating.

Phase 2:

Re-Wild (9 dAys)

The purpose of the second phase is to reintroduce friendly prebiotics and probiotics to support the friendly bacteria in your gut.

On The Menu: Fermented foods and drinks to increase the healthy microbes in your gut – think kefir, kombucha, pickles.

Limited Foods: Beans and pulses, with eggs gradually reintroduced.

The Aim: Continue with gut-soothing foods, but add in gut-boosting prebiotic and probiotic foods.

The Bonus: Diversity. That’s the G Plan Diet’s buzzword!


Rebalance (7 days)

This is the week where you become the decision maker. As gut-irritant foods are gradually reintroduced, you have to determine how or whether it affects you. It’s also all about maintenance of the diet for the future.

On The Menu: The full repertoire of theG Plan diet recipes.

The Aim: Reintroducing possible gutirritants – dairy, gluten and chilli – that were eliminated in Phase 1.

The Bonus: A small glass of red wine every few days! Don’t forget to weigh and measure yourself at the end of the 21 days.


All the smoothies are based on bananas, which are packed with gut-friendly prebiotic fibre.

Berry banana

Phase One breakfast

Berry banana


» 2tbsp mixed berries, fresh or frozen
» ½ banana

» 1tbsp gluten-free oats

Phase 2: Replace some or all of the liquid with probiotic-rich, dairy or coconut kefir.
